  1. There are some RoIP boxes out there that allow radios to be connected to IP networks for remote control. But I don't know of any that have a phone app that are reasonably priced. That being said. And mind you, this will require some Linux and Asterisk knowledge, but there is the apt-rpt add on for Asterisk that will allow a radio to be connected to an Asterisk server as an extension and then you can use Zoiper or another soft phone app on your mobile to connect to the radio. Cost is no more than the interface to the radio which can be built with a few parts and a CM108 USB sound card dongle. I think they are about 10 bucks all in if you build it. But you are going to need to load and install all this (Linux, Asterisk, apt-rpt, and Zopier) and configure it. If you are computer savvy, and know how to solder, then it's not a huge deal.
  2. Something to keep in mind. Ham radio satellites are running 1 to 4 watts. Ham radio satellites orbit over 100 miles from the earths surface. So it has a LOT to do with line of site and less to do with lots of power.
  3. One option is Zello or one of the similar applications that link a radio to the internet for remote operation. You would need to run an app on your phone that would connect to your radio directly and allow you to operate it from the phone. The cost for this sort of thing can be reasonable or expensive depending on how you interface it and what service you use. I will not go into the specifics of it here but it's worth researching if you are wanting a solution that basically works anywhere you have phone or wifi service.
  4. Hold on for a minute.... before we start looking at more power, lets look at something else. Namely your receive signal level. Is the signal coming from the repeater full quieting and strong or is there noise with it? Do you have a 'bar' type signal level meter on the radio? If so is the receive signal full bar's or just one or two? Increasing power output can correct poor signal to a receiver / repeater, but it does NOTHING for your receive. And having some sort of obstruction between you and the repeater can NOT be corrected with you increasing power. What do you know of this repeater? Is it a high profile repeater on a tower with 200 foot or better antenna height or is it some mail order antenna built in a piece of PVC pipe 12 feet in the air on somebodies garage? Is this the only repeater in your area, or are there others? If there are others, what sort of performance do you get with those other repeaters? Are those repeaters closer to you or farther away and are they in the same direction from you or different directions? Next question, do you have a metal roof on the house or is it shingle? You are not going to get signal out through a metal roof. You would be better off to put the antenna in a corner on the highest floor that wasn't in a metal roof if that's what you have. Point is that 7 miles to a good repeater shouldn't be an issue from a handheld radio. Even a really cheap one. I am surprised that you even need an external antenna to talk 7 miles to a repeater. But since you do, I am wondering why that is and if putting more power in the air is going to solve anything.
  5. Then he goes after the guys insurance company. That's why people are required to have insurance. And he gets a NEW tower, professionally installed at the guys expense.
  6. First question is how bad is it bent? If the tower is bent to the point the leg / legs buckled then you can't fix it. It has to come down. At that point you need to figure out the cost to get it down safely. It's obvious that it can't be climbed in the condition it's in. Leaving you with few options. You didn't mention the height of the bend, the direction it's leaning, what it could fall on or what access there might be to get up to it with a bucket truck and crane. Give a detailed description here and pictured if you can get them be fore a real discussion can happen.
  7. Well, it's gonna depend on the situation. The terrain that you are communicating across, the gain of the antenna's at both ends, the height of the antenna's at both ends and lastly the power at both ends. First scenario. Simplex communications between two vehicles since we are talking about using 50 watts. Antenna heights are roughly the same, and no obstructions between you and the other vehicle. Yes, there is a difference here, being the distance that stable communications can exist. You are not limited by the other end being lower, or having less antenna gain. So it will matter in this specific situation. Second scenario, Simplex to a portable (handheld radio). In this instance the 50 watts is completely useless. The other end of the conversation has neither the ability to match your power or antenna gain. Height may be similar, but they are giving up 10dB of signal level (5 watt radio). They are also giving up an additional 3 to 6 dB of gain or possibly more due to the portable radio having an antenna that has little to no gain. You will loose the ability to hear them long before they can no longer hear you. Third scenario, repeater use, repeater with 200 foot or better antenna height, antenna has gain. Here is where the power MIGHT have some advantage, but typically not. For every time you double the height of an antenna you gain 6dB of perceived gain. It your antenna is at 10 feet (a bit high for a mobile but easier to run numbers) you get to the point that curvature of the earth plays a bigger role in creating an obstruction than the path loss for the distance given. On flat ground, the horizon due to curvature is 11 miles. Meaning that LOS or Line Of Site exists at ground level for that distance. Once you are further than that away, the ground becomes the obstruction. As you raise the antenna up, you regain LOS for a specific distance per 10 foot of height of antenna. It's not really allowing you to 'see' over the horizon, it actually placing the antenna back into the LOS due to the increased height. Remember with this, UHF signals travel in straight lines. Lower frequencies behave differently. But GMRS is 462/467 so we are staying with that. The 'path loss' which is the amount of signal loss over a given distance between two antenna's in open air isn't going to be great enough to attenuate the signal of a 50 watt radio before the curvature blocks the signal. This even applies with antenna's that are significantly higher than 200 feet. Consider that ham operators operate portable radios with modest gain directional antenna's and communicate with satellites that are hundreds of miles away from them in space. With 5 watt handheld radios. SO again, path loss is NOT going to have any effect. And 50 watts or 500 as you stated, will NOT defeat the ground blocking your signal.
  8. Well, this is a loaded question. And the owner of the tower is the one that's going to load it. You are going to have 3 main types of tower owners. Knowing who owns it and the ground under it is going to be key in how you proceed and what to expect. First you have the 'vertical real estate' companies like American Tower and Crown Castle. They own a vast number of the towers that you are going to see. They are teh most difficult to deal with but the most willing to take your money (a LOT of your money) to allow you to access their site and put up your gear on their tower. First requirement is going to be the climbers or 'tower crew'. Some of the major players will allow anyone that is licensed and bonded to work on their towers. Others will require that you use only specific companies that are 'on their list'. Sort of like preferred body shops in the auto insurance business. But be assured that YOU will NOT be climbing their tower and working on it at all. They also may or may NOT have a structure on the site that they will rent you space in. Mind you this is a separate fee from the tower access fee. Then they may or may not require you to install at your expense, an electrical service for your equipment. Lastly, most any of them will charge you a civil engineering fee to verify your antenna and line are not going to overload their tower. I have seen this fee charged to people to access old microwave towers that you could literally hang a truck from without overloading it. This is usually around 3000 to 4000 bucks. And if it doesn't pass they will then ask you, at your expense, to reinforce the tower (tens of thousands of dollars typically) before you are allowed to pay another company to put your single antenna and line on their tower. These people deal with cell providers that make thousands of dollars a month on these towers. The cell companies don't care about all this because they make all the money back in a few months to a year. Or, because they rent thousands of other sites from the company, the owner does the work and increases the rent a few bucks and gets their money that way. Of course marking up the work a good bit. Again, the cell companies don't care. They have the money. Oh, and your install better be top notch. Not to mention that they will only write multiyear contracts that are going to typically be at bear minimum 500 a month in really rural areas to thousands a month for urban areas that have more people. Second is going to be the private owners that know the business, or are a small player (own a few towers and not thousands). Some times you will run into these folks and they might even be a ham operator that might support your endeavors that will rent you space for a reasonable fee, provide power and a place to put your gear but still has the good sense to require licensed climbers. However he may know a guy that he uses and will allow you to work with him directly to do your work as he is doing other work on the tower (maintenance or whatever) for a really reduced fee. These are the folks that you hope to encounter in truth. Last ones are the unicorns. These are the property owners that got a tower dumped on them due to the previous tower owner going bankrupt (lots of old paging and small cell upstart companies did this). They have little to no idea about the tower, how to maintain it, what requirements for lighting it may have and typically shut the power off to the building years ago. If you know radio, towers, and building maintenance, you can sometimes work yourself into dealing with all that for the property owner and getting access. But if there is no utility, you will be the one to deal with that too. Last ones are the owners that are somewhat radio savy, or at least ham / GMRS friendly and will allow access for a fee, or not based on no given reason. These situations are great until they aren't great. And this sort of goes for the guy above as well. When they hear that they could be getting thousands a month in rent and you aren't paying that, you have no agreement, and you will be out the door. They may even try to keep your gear. It just depends on the person. So good lick and I hope it works out for you.
  9. Well, they are indicating that they welcome reporting. But the reporting they want isn't of the specific violation, rather the act of the violation causing interference to another user. So it basically reads they don't care unless you are specifically interfering with the operations of another on the frequency. Mind you I am not trying to say it's legal through a lack of enforcement, nor will this cause me to put my repeater back on line. I just banned from my equipment an entire group that owns and manages a repeater to the east of me due to the actions of another operator. He decided to send me this long text about an operator that was using their repeater without permission, then causing issues on a ham repeater. Problem was that I have been friends with the guy he was accusing for over 30 years. He expected me to get enraged about the situation, so I did. I banned him, and his group of repeater owner / managers from using my equipment. And I am about to the point I will be putting up a repeater on a different frequency that will have double the coverage of theirs and try to make daily contacts with the individual that he was complaining to me about, hell I may put HIS call sign on it and turn it over to him once it's operational, just to drive the point home. And I can do that as long as it doesn't interfere with the operation of their repeater and there isn't ANYTHING they can do about it. Of course I will not have he laundry list of demands to belong to their group and have access to their repeater either. Because, yes, I am that guy. Problem with banning all those folks is they / he (no names given on purpose) are the type that will turn me in for interference even when none exists. I have the GMRS repeater with arguably the greatest coverage in the Central Ohio area. And I am not going to risk, at this time getting a report of causing interference placed on me because I wasn't fair when I banned them from my gear. And the person that started all this, well it isn't the first time that he's caused issues. I am pretty certain that he's the one that got all bent a couple years ago when the operator up in the Northwest got drunk and was on the radio. I believe it was that same individual that contacted me then and ask what I was going to do about an operator that was 3 states away from me operating a radio while drunk. When my reply wasn't to his liking, he then got mad at ME for not doing anything about the actions of another operator. So I banned him then and forgot about it. Since I forgot about it, he got back on and I just let it go. Then he pulled the latest thing and I banned him and his group from my repeater. So he got to explain why his entire group got banned from the repeater. Because, again, I am that guy at times.
  10. And in this case, they don't seem to want to provide that clarification. So let's try to decipher their version of interference, because that's the sticky part. There is a requirement to monitor the airwaves before transmitting on a frequency or any frequency used in the output of a repeater. So the situation would need to exist where two repeaters on the same frequency existed, one being linked and the other not linked. To create interference, a user would need to know there was a second repeater on the air in a given location that was not linked and know that it was in use when you keyed up into another repeater that is linked to that other linked repeater then causing interference. Here's the problem with that. No GMRS type accepted radios that are truly Part 95 compliant have a HUB defeats PL/DPL in them. At least none I am specifically aware of and others are welcome to comment if they do exist. Going on the fact that functionality doesn't exist in all type accepted radios, there isn't a way to 'monitor' the frequency prior to transmitting on a local repeater that shares the frequency with another repeater. So the fact that you are talking through a linked repeater in another state that you can't hear for obvious reasons, or that you grab the mike on your part 95 radio and go to use it, due to the fact you don't have a hub defeats PL OR an unprogrammable busy channel lockout that can't be defeated, you would be in violation of the 'interference' regulation in both instances but the FCC not requiring a busy channel lockout or hub defeats PL function in the radio that wasn't able to be disabled gives anyone that would do this a way out and arguable defense in court. Basically, it would use their regulations and type acceptance rules against them when they accused you of causing interference based on what they came up with for a reply to you. I am not a lawyer, and don't claim to be. I just take their logic in this case and their written regulations and turn them around as a defense.
  11. So basically they are not answering the question and instead asking if you are aware of it causing any interference and then directing you, IF you know of it causing interference to report the INTERFERENCE. Not that people are doing it, but if the repeaters that are doing it are causing interference by doing it. We know that they know that it's being done. And they seem to be unfazed by that specifically being done and only seem to be interested if it's causing interference. I have no idea what the take away is on all thins, but is sounds like they really don't care or are willing to take a stance on it one way or another if there is no interference present due to it happening.
  12. And that right there is what I am afraid of happening on GMRS. I don't make many friends by running repeaters and having that sort of thing go on. That would get Net Control banned from my repeater pretty much on the spot if I heard it happen. Newbies hear what we do and will imitate it because they don't know any better. That's the reason we don't let folks get drunk off their ass and talk on the repeater, because the minute one guy does it, everyone else thinks it's OK if nothing is said. But I would still rather hear some one three sheets to the wind on the air, than a guy that believes he needs to ID every 10 minutes and use phonetics for his call every time he ID's when he's full quieting into the repeater. Again, personal opinion but we all have those.
  13. No, that wasn't said specifically. Just commenting that it's NOT required, and can be annoying when you have people that do it all the time on an FM repeater, regardless of the service. And I did say that on HF it certainly has it's place. Of course I got gifted with Victor Uniform Lima, which sort of sucks both phonetically and with CW for trying to work a pile up. So I went a different route dealing with that. Big Amplifier, bigger antenna. Gonna slip an audio compressor, gate and processor in the mike path and get the 'voice of God' thing going too. But that's another story for another time. And there will be no doubt that some will find that as irritating as I find phonetic call signs used on FM repeaters as a default rather than only when needed. But yeah, there is a bit of jealousy in there too. I would rather be hollering some like Kilo Siera trying to work a rare bit of DX than Victor Uniform Lima. Might have to put a digital voice recorder in the audio path as well and just have a button to do that.
  14. So, I am gonna scuttle all the SAD HAM dreams of full phonetic call signs here and now. There is ZERO requirement for a call sign to be said phonetically. It is done when needed to communicate a call sign to a receiving station when signal levels are not great and you are wanting to get that information through. My call sign as assigned by the FCC is WRKC935, NOT Whiskey Romeo Kilo Charlie niner three five. NO WHERE on my FCC license is listed anything similar to that. Or even sort of close. All it says is WRKC935. Ham is the same way. KB8VUL is my ham call,,,, not the phonetic equivalent. Hammie's use phonetics a lot on HF and for good reason. You are trying to communicate great distances at times with less than 100% copy-able signals and are fighting noise (QRM and QRN) to make contacts. We are not using HF, SSB, QRP (weak signal) and typically not using simplex, we are talking through repeaters that provide us solidly copy-able signals. So using ITU phonetics, LEO phonetics, or adhoc Phonetics (crap we make up on the fly) just adds to the syllable count. I know guys that do it, some have a Z at the end of their call sight and can't help but say Zed. Other guys are all phonetics all the time. But there have actually been questions raised by others if ONLY giving your call sign phonetically is actually legally IDing you station at all. Because we come back to what was issued by the FCC. Especially if non-ITU standardized phonetics are used for a call. Consider this. How many radio stations, commercial radio operators, public safety dispatchers or for that matter, ANY other radio user outside of Ham radio use ITU phonetics outside of maybe the military use phonetics for anything outside of reading license plates, VIN numbers and other specifically alphanumeric number/letter groups including their call signs. Phonetics are used to save time when signal degradation is expected, such as in HF or weak signal communications. And it has it's place there. Not on FM repeaters with full quieting signals. Or when someone is copying alphanumeric groups that need to be accurate. If there was a specific requirement for us to log every contact we made with date, time and call sign then it MIGHT apply, but only if you are ask to REPEAT your call because the other party didn't get it accurately. That's my take on it. Of course you know what they say about opinions.
  15. This is going to be an application that will require coming up with something on your own. You are going to need to design it and build it, or have someone do that. Obviously there was an option for them, and I don't doubt that there were a few factory made units. But those don't seem to be surfacing. Either the few that were purchased are still in use, or they were scrapped instead of making it to the secondary market. But designing an amplifier for this application shouldn't be all that difficult, at least if you have some sort of accessory connector on the radio that has a keying output for the low band to control the amp. It's going to be a bit more complex than a CB amp due to the requirements for proper biasing of the driver and output transistors for proper linearity due to it being FM and possibly P25 (don't know if the radio does digital modulation on low band. Power output is going to depend on your amplifier design, which will no doubt will need to be multistage since the initial power level being amplified is rather low. But if you design for a 10 dB increase in power per amplifier stage, then it's just how many stages are needed to reach the desired power output level starting with what you have. The other positive to this is it's low band (30 to 50Mhz). By that I mean that things like the trace length in the circuit board don't really become a factor at those low frequencies. If this were 900Mhz or even 440 to 450Mhz then even the design of the circuit board, trace capacitance and inductance comes into play and needs to be considered for the design. But again, that's not really a factor here.
