Compander = Compression & Expander. The idea of a Noise Blanker - at least as I understand how it was implemented in Low Band radios by Motorola - was a secondary receive circuit slightly off-set in frequency, and that would be used to compare desired signal vs. undesired noise (Figuring that most lower frequency "noise" would be wideband in nature, while the desired signal would be on-frequency). In Compandering, Audio is compressed upon transmit, and expanded upon receive. This allows for a potentially better "envelope" of audio response to be compressed into a given amount of bandwidth. However, it requires more manipulation of the audio components of human voice. You give up a bit of audio purity when using Compandering. Better or worse is often up to the ears of the people using the system (and in my experience, how often the people using the system are pressing the outer edges of coverage/range). There's already a ton written about this type of stuff out there on the internet, so the best way I could describe it is to say that if you're only concerned about quality of audio within your own fleet - give it a try & see how it works on your radios and in your system. If you like it, certainly use it for your system. However, most GMRS radio systems and user groups aren't running Compandering, so your radios would sound "odd" sending out compressed audio to another radio that wasn't set to receive (and expand) the compressed audio.

With 5/8 wave it should be a coil that does matching, to balance out the big -jX component, but I may be wrong here - working from memory, and too lazy to check on internets. "Colinear" usually means 2 or more sections in line, but also could mean that Midland marketing dept found a cool scientific-sounding buzzword. You are absolutely right about adjusting to minimum reflected power. I think moving antenna back and forth on a lip mount will not make a big difference, if any, but worth tying. Good practices means that your soldering and crimping is good and no sharp bends of the cable. I tend not to use RG58U in my car installs, I prefer RG8X or LMR-240. However, if you already have cable and connectors, it's fine. On 8' length difference in attenuation is negligible.

It IS interesting and I don't know if it repeats on the same frequency hopset or not. I don't know the details of how it works. It would be interesting and cool to try but I don't feel like spending the $,$$$$.$$ for a DRX. I think the cable that comes with the DRX for connecting the two units together is 10 ft or 20 ft long. There is an optional 50 ft cable for it to get the two units further apart. The current DRX based on a pair of DLRs is a refresh of their older DRX unit which was based on a pair of legacy DTRs and with the same price tag. The legacy DTR410/550/650 models were discontinued in November 2018 when the DTR600/700 models were released. Cane Wireless needed to develop a DLR based DRX going forward. The DRX also needs to work with the Profile ID mode channels which the legacy DTRs can't do because they don't have the 4 digit PIN feature. From what I read about the DRX is that the digital audio delay between radios approximately doubles when talking through the DRX. Multiple DRXs on the same channel can be used to further extend coverage on a channel but Cane Wireless recommends against it because the audio delay increases and audio quality may decrease. This makes me wonder if analog audio passes between the two units making up a DRX repeater. The audio quality would decrease due to effects of double vocoding, etc.

That's something I had lingering in my mind after reading your links and studying DTR/DLR thing. I'll leave hacking for some time later. The first thing (ok, second) is of course, to plug in simplex repeater and bring the whole contraption high up on a makeshift mast. That's could be a lot of fun, I already see it.

Yeah, top, bottom, side, other side... Not front. Btw, on TK-880 it's reversible, you can have it on the top or the bottom.

If all radios involved in communication used complementary companding circuits it can have the effect of improving the signal to noise ratio of your audio. However, if both sides of the communication chain not using it communications may not sound as good to you or to others. If you have every heard the term ‘Dolby’ or ‘DBX’ with regards to audio recording noise reduction, both of these were variants of ‘companding’ circuitry/algorithms. Both squashed the dynamic range on the input side and expanded it to normal dynamic range on the output side in an attempt to decrease the effect the noise native in the audio recording medium. I would advise not to use it unless the only people you are communicating are equipped with compatible companders and you have little or no need to talk with anyone else.

Yes its only a scanner for the other bands.

I think the KG1000 is receive only outside of the GMRS band. That being the case, you will be fine with the antenna you have as it should pick up just fine if not being absolutely optimum. I would personally put the effort into putting your existing antenna up as high as I could get it.

SWR 1:1 does not necessarily means that your antenna is at resonance. It means that it's well matched. Assuming there is no big loss in your feed line (that eats up forward and reflected power), the lower SWR, or reflected power, the better the match. And antenna does not have to be resonant to be an efficient radiator. Resonant quarter-wave above ideal ground has 36 Ohm impedance and SWR 1.5:1 when connected to 50 Ohm feedline. So, tune for lowest SWR, i.e. for lowest reflected power. Use good practices to ensure minimal possible loss in the feed line.

You would want to swap to a dual band antenna if you plan to TX. With that said without your ham radio license you can't TX anyway. WX channels should work ok for RX on a UHF antenna. Depending on what your listening to in VHF the UHF antenna will hear some but degraded. You license shows Florida so not sure where in NY you are listening. CNY has a couple repeaters but not many in upstate NY.

Did you go to the main page ? https://mygmrs.com/repeaters If you go here and click on the repeater you want to use and request permission its up to the owner of the repeater if he wants to get back to you or not. Alot of these repeaters may have changed over time and using the map with updated stuff is normally best. Remember repeaters are private property and there is no need for them to approve you if they dont want to. It could also be they are busy and dont have time to reply to an email right away.

I would use a simple black 1/4 wave for UHF. its 6" and will blend in. It will work night and day better than the phantom or stealth antenna

I'm definitely interested in seeing what the MXT500 and 575 will have to offer.

If your feed-line loss is high, your SWR appears artificially low. Add enough loss and ever the worst case real-world SWR will appear perfect at the radio. Michael WRHS965 KE8PLM

DoubleQWOO - Yikes!

I certainly wouldn't announce in a public forum that I plan to break federal laws. Sent from my Pixel 4a using Tapatalk

They were down for maintenance in the wee-hours last night. I waited for it to go back up and snuck in my application for a ham vanity callsign before they start charging for it. Ka-ching!

WQWU626 This is exactly what I need. I ran a rough estimate, and I will cover most of the county in all directions using a 40' antenna. Thank you

Here is where you can generate "maps" of your expected coverage based on the data you enter. This program will also consider topographic data. The 'green' areas are predicted HT @ 70% reliability, the 'yellow' areas are mobile coverage @ 70% reliability. This was for a proposed repeater to be located near Schaumburg, IL. Unfortunately, after a detailed site survey we determined that there would be to much potential for conflict with all of the other repeaters on the 150' tower. https://www.ve2dbe.com/rmonline_s.asp

That won't go over so well is absolutely right. The Ham bands are ALWAYS being looked at by various groups to use. Hams already lost part of the 1.25 meter band due to UPS wanting it. At the site below look under the section heading "U.S. reallocation" for a brief history lesson. https://en.wikipedia.org/wiki/1.25-meter_band Hams have to constantly watch their bands for illegal CB'ers on the 12M and 10M bands, local TV stations on the old analog channel 2 made 6M almost unusable in those areas, fishing boats - high power Chinese cordless phones among other junk operating illegally on 2M, and on 70cm there is a low power commercial allocation at 433MHz, right in the middle of the band. Hams also had to deal with some companies using parts of 70cm for police drones etc. not to mention the band is shared with the US military. The later was an issue with the military Pave-Paws radars. http://www.arrl.org/news/air-force-pledges-continued-cooperation-with-radio-amateurs-during-cape-cod-radar-upgrades
