I use Tram antennas on my vehicles. On the new car we used an NMO magnetic mount for it. Works great, https://www.amazon.com/gp/product/B0043310ZO/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

The 49D software is rather straight forward. hook the cable up, install the software and run. You need to read from the radio (Make sure your com port settings are correct) then you'll have a screen where you can start entering channel information and stuff. Remember for repeater frequencies, the 462 frequency goes under receive, and the 467 goes under transmit. You have a choice of CTCSS (PL) or DCS (N and I) tones. Just enter the info in, keep everything wide band and you should be good.

New Interfering (IX) Signals - "Baby Monitors" using GMRS/FRS
WRAK968 replied to intermod's topic in General Discussion
Unfortunately many of these devices are likely to be chinese made and the companies won't respond or react to any FCC violations but rather change marketing names as to continue selling in the US. E-bay doesn't help the situation much either. I have seen several devices from chinese manufacturers ranging from monitors to two-way intercoms which look to operate in the 462/467 range and as you mentioned above, they all operate on a DCS code. Some even advertise that they will work with two way radios, giving the frequency and DCS code in the ad. In the end, the end user is the one responsible for use and operation of non-certified transmitters. Most times simple education and assistance is all that is needed to get companies in the right direction (Many don't wish to receive a fine, but many more do not want to face the legal ramifications should private personal info be released into unsecured airwaves)- 44 replies

I had issues with uploading photos in the past. I spoke with the site owner about it and he mentioned something with the server's code being out of date which prevents photos from being uploaded to the board. I know he's been working to fix the issue but we all have a life outside of here and with a total site re-write and building up an ROIP server for GMRS as well as running the northeast net and real life stuff that Rich has been involved in, Im sure the photo issue has been put on the back burner for now.

The frequencies you are trying to use are for ham radio, NOT for GMRS, and transmitting on those frequencies with your GMRS license could result in fines and termination of your license to operate on GMRS. Please review part 95E rules with the FCC. §95.1763 GMRS channels. The GMRS is allotted 30 channels—16 main channels and 14 interstitial channels. GMRS stations may transmit on any of the channels as indicated below. a: 462 MHz main channels. Only mobile, hand-held portable, repeater, base and fixed stations may transmit on these 8 channels. The channel center frequencies are: 462.5500, 462.5750, 462.6000, 462.6250, 462.6500, 462.6750, 462.7000, and 462.7250 MHz. b: 462 MHz interstitial channels. Only mobile, hand-held portable and base stations may transmit on these 7 channels. The channel center frequencies are: 462.5625, 462.5875, 462.6125, 462.6375, 462.6625, 462.6875, and 462.7125 MHz. c: 467 MHz main channels. Only mobile, hand-held portable, control and fixed stations may transmit on these 8 channels. Mobile, hand-held portable and control stations may transmit on these channels only when communicating through a repeater station or making brief test transmissions in accordance with §95.319©. The channel center frequencies are: 467.5500, 467.5750, 467.6000, 467.6250, 467.6500, 467.6750, 467.7000, and 467.7250 MHz. d: 467 MHz interstitial channels. Only hand-held portable units may transmit on these 7 channels. The channel center frequencies are: 467.5675, 467.5875, 467.6125, 467.6375, 467.6625, 467.6875, and 467.7125 MHz. §95.313 Penalties for violations of the Communications Act or FCC rules. Operators of Personal Radio Service stations may be assessed penalties for violations of the Communications Act and the FCC Rules. a: If a Federal court finds that a Personal Radio Service station operator has willfully and knowingly violated any provision of the Communications Act, that operator may be fined up to $10,000 or be imprisoned for a period not exceeding one year, or both. Upon a subsequent violation, the imprisonment may be for a period not exceeding two years. See §501 of the Communications Act (47 U.S.C. 501). b: If a Federal court finds that a Personal Radio Service station operator has willfully and knowingly violated any FCC rule, the operator may be fined up to $500 for each violation, or in the case of a continuing violation, $500 for each day that the violation continued.

programming radio to repeater. Motorola vs chirp
WRAK968 replied to WRFV510's question in Technical Discussion
The XPR series programs differently than conventional radios do as they are digital radios, even though you are using it in analog. Assuming you know what you are doing with the programming, to set two different tones on CPS 16, you simply select the tone you want for RX under the RX box, then the tone you want for TX under the TX box. Those tones can be the same or completely different. To my knowledge Motorola radios are not friendly with Chirp as the firmware on the radio is proprietary. -
Its the duplexer. I have an antenna about 20 feet up and had the same issue until I replaced the duplexer. Easy way to tell is to turn the repeater to low power (This is one of the things that increased range for me) If you get a little more range then you know for sure, but of course this doesnt make up for the duplexer being installed backwards, or if it is way out of tune. As you have just started I do not know your skill level so Ill explain what the problem is: A duplexer separates the transmitter and receiver signals, thus anything the transmitter is putting into the antenna shouldn't be able to get to the receiver. When the duplexer is damaged, out of tune, or installed improperly, the receiver can still hear local signals through general proximity and even by using the jumper as a sort of antenna. This would be why you can use the repeater when you are close up. However when you leave the signal fades away, just as it would if you placed a portable next to the repeater. The transmitter doesn't help as its signals also overpower any other signals and causes what we call "De-sense" which is a situation where the transmitters signals are blocking any other signals from getting into the receiver. De-sense usually occurs when no or a slightly out of tune duplexer is used. It would seem from what your explaining that the RX side of the duplexer is out of tune causing your de-sense. The other cause would be crapily built duplexers. China has flooded the market with these stupid things and I've been a victim of their lower prices. Since I upgraded to a DB BPBR duplexer I have not had an issue with de-sense. Check to see what duplexer the seller has sent you. if you have a flat-pack (Notch type duplexer) perhaps he can upgrade you to a BPBR (Band pass/Band reject) type duplexer for a small fee. Never hurts to ask and made a world of difference for me.

I'd like to use my Yaesu FT-60 for GMRS repeater
WRAK968 replied to kaos26's topic in Amateur Radio (Ham)
The FT-60 is a ham radio and will work on ham frequencies only until you do the MARS mod. My father uses his FT-60 on GMRS for repeater controls only (Its the only radio he has with a DTMF keypad) so it will work, but would be frowned upon by quite a few. -
Noob Questions - so many ! So excited!
WRAK968 replied to Ant1841's question in Technical Discussion
1: Wifi works in the 2.4, 4.9, and 5 GHz band while GMRS is in the UHF (460-470 MHz) band so you shouldn't see any RF interference, however there may be electrical interference if using a cheap transformer. (This would be an audible hum over your voice as you transmit) 2: Midland and Baofengs are ok, (I have a Baofeng that I use as a loaner radio for family members) Personally I prefer Kenwood radios, using 380 portables and 880H mobiles. They are easy to program via computer and have a few features the baofengs and midland's don't have. Recently I started using an 8180H which has even more features on it. It all depends on what you plan to do with your radios. For me, being able to use work frequencies was the reason for upgrading to the 8180. 3: An antenna in the attic does work however just getting it to outside can result in a drastic increase of range. For the past two weeks my antenna was in the attic due to work being done on the roof, it got the signal out but not too far. When I returned it to outside I realized what a difference a sheet of plywood can make lol. 4: As Cleveland said, the traffic you are hearing could have a code or a mix of codes set up, they may also be using a repeater which could let you talk as far as 40 miles away. On top of that, GMRS repeater owners are now adding linking computers and software to their systems which can allow a user from NJ to talk via radio to a user in CA. Information about repeaters and which are linked can be found on the MyGMRS.com site 5: See Cleveland answer Even though I started out as a ham, this site, this community even, has helped teach me so much. When there's a problem I have never seen a group come together to try and figure it out then wait to see if their answer resolved that problem like they do here. This is a great group of guys and gals from all walks of life with experience from the amateur radio community, emergency radio community, and even professional radio techs, so there are no shortages of answers to your questions. -
Setting up repeater for GMRS radios compared to base station
WRAK968 replied to AlphaTango15's topic in General Discussion
Your first goal should be to figure out how far you need to communicate. Is it just across town, or 20 miles away? Will you be using mobiles or portables as a primary radio? Are you talking between houses or to individuals? Finally are you communicating with just family or are you looking to talk with other operators, or use it for emcomms for groups like C.E.R.T. Some of those questions determin if you need a repeater, or if simplex operations will be sufficient. They also help you decide what equipment you may need to use. When considering a repeater you have more questions to be answered: Do I have a way or means to get the repeater operating properly? Do I have a place to store the repeater? Do I have the funds and skill to install, test, and maintain the repeater? What would I need to achieve my goals with a repeater? I'll be honest, when I started with building a repeater there wasn't any in the local area. (The LEH repeater is still the only repeater in the area as the Tuckerton unit was taken down) My goal was to increase portable range from the house to talk to mobiles across town, and to be able to direct link the repeater to another repeater at a family members house allowing the family to talk as a group. Since then, I have been striving to increase range, purchasing better equipment and getting the antenna up higher. In all the LEH machine had the following costs: RKR1225: $550 DB duplexer: $325 Feedline: $75 Lightning arrestor: $35 antenna: $175 Antenna mount: $45 Antenna mast: $75 Back-up battery: $75 Pi & RIM: $150 Cabinet: $75 Test equipment: $400 (Includes SWR meter, dummy load, exc) In total this came out to nearly $2000 to meet my goals, and that doesn't include things like duplexer tuning, programming software (Which I had to buy a dedicated computer for) or the time needed to inspect, diagnose, and repair problems which come up. -
There are quite a few radio shops in the NYC area. I personally use A&R communications which is in NJ. You can try Barry Electronics 224 W 35th St #408, New York, NY 10001 They sell ham radio and commercial LMR and such

FRS frequency being transmitted on Repeater channel?
WRAK968 replied to Mikeam's question in Technical Discussion
If you ask me there is an issue with the repeater. That is WAY off frequency meaning the RX side of the repeater likely needs service. -
The cobra and Zastone have DCSN and CTCSS, and the Icom I know has DCSN, DCSI, and CTCSS. (I program the VHF version of the 4000 series for work)

I think that because they TX higher than 2W and include the 8 repeater channels these would have to fall under the GMRS license rules vs bubblepack radios that only transmit at 2 watts and only have the 22 channels without repeater inputs. According to reviews I've read (I do not personally own the radios myself) the range on those radios is only about 1 mile despite the advertised range of "25 miles." There also seems to be an issue with battery life and waterproofing. For the price, it might be better to go with the Baofeng GMRS-V1 which will allow you a couple extra features over the motorolas. (For instance you can use split tones with the baofeng if a repeater calls for it, and I believe the baofeng also has a vehicle charger that is comparable with the GMRS-V1) In the end, Im just a guy going over rough specs and reading reviews so feel free to listen to other users here for their input as well.

most radios have both CTCSS and DCS, The DCS codes normally start with a D (D223N, D223I, or D223) while CTCSS codes are just a number (127.3.) With DCS it is important to observe if the code is inverted or not. This can usually be found on the last digit of the code. D223N and D223_ are the same while D223I is inverted. Check with your radios settings or post the model here and we may be able to help you find the setting you need.

1225 Ver 4 WILL work on XP set up as a VM. Its a bit of a pain to do if your not well versed with computers. I found it was much easier to, and you may be better off this way, purchase a cheap xp or 98 laptop and loading the software on there to do your radio work. That way you dont have to do all the stuff to get the VM running and hoping all the updates are there to allow it to access all the ports on your computer and such.

As far as rules go, the license holder is responsible for how the radios are used. Lets say the family in NY program a part 90 radio to receive the local FD, however due to an error they transmit on the FD channel and give your callsign, you could be on the hook. Now this is a bit exaggerated but has happened from time to time. Another example is the family in NY using a radio that is not certified by the FCC and causes interference on another channel. Or, because they are in NY, using channels 19 and 21 north of line A (I think those were the channels) which is also an easy violation for someone to make if they haven't read or understood the rules. How I manage everything is, I program the radios under my callsign myself. By doing that I can assume all responsibility should something go wrong. My family knows and understands the rules of GMRS, and everyone has a 3 digit ID code, (First digit identifies the location and last 2 are unit numbers) So if a complaint comes in about WRAK968-103, I know its my brother, 202 is my step mother and so on. Some people use one digit ID, (WRAK968-1). The three digit system may work for you so that should there be a problem you will know where the problem is, and possibly who the problem was caused by.

You should be find with a 15W DC power supply that outputs 12.5-14V DC. You can get them for $20 on amazon.

Works great. I use the digital side for ham radio and then can switch up to GMRS analog. Programing is a bit confusing so make sure to look around youtube to learn how to program channels into the radio. (Its a long process but if you miss a step the "Channel" wont even show up in the radio) I seem to be able to hit repeaters about 15-20 miles away with it. The only downside I have found is the programing process which as I said is a bit confusing.

I received my license after the rules change, however the line restriction is still printed on my license, so Ill say the rule still exists in some form. This rule was typed word for word from my license.

Not exactly what was asked (They know about the local repeaters to them) but good information anyways.
