I don't have any options moving it forward or backward. I tried moving it 6 inches to the left and then right, but haven't noticed a difference. Maybe it needs more as you are suggesting, like a foot at a time. I can't hit the repeater on the 935. I don't know if this matters but when I key up on 462 I only have about 1.2 SWR, but on 467 it is 1.8.

I didn't mention this in the original post but I can communicate with my family who are on 935's 5 miles away on channel 17, so I don't believe it's an audio mike issue. From what I can gather while reading, it appears to be fairly common to be able to receive farther out than you can transmit, particularly when in terrain like I am with trees, elevation, and buildings in the line of sight. I'm fairly disappointed they steered my towards the coax they did knowing I was going to be running UHF. I imagine I have a lot of loss with 75 feet. Spent a lot of money on it as well, so I don't want to just swap it out.

I edited my original post as I used the incorrect phrase line of sight as opposed to straight line. I am in rolling hills and tree cover, so I was amazed to clearly hear people on a repeater 14 miles away. Expected 5 miles with my setup so pleasantly surprised.

Correct, I can clearly hear a lot people using the repeater. When I try and chime in, no one can hear me, I just get a brief RX signal on my radio.

Headed to an emergency service call so won't respond till tonight, but thank you for all the help.

Bummer, the guys at BUYTWOWAYRADIOS told me this was the best coax I could buy... I have a lot to learn!

For instance, this is how it is listed in CHIRP: 29 462.7000 RPT-21 + 5.0000

I'm a little confused now. As the chart below indicates the GMRS repeater channels, it is the same on the CHIRP software. I don't know if I misspoke, but if you have RPT 21 set to an offset of +5 would this not corelate with the below chart of RX 462.7000 and it automatically set the TX to 467.7000? Why would they list it this way if I am supposed to reverse it, being that this is not simplex, but repeater 21? I want to be clear I'm not arguing and that I am inputting it incorrectly, I'm just trying to understand the way it is written. GMRS Repeater Channels and Frequencies Channel RX Frequency TX Frequency Max Power Bandwidth RPT15 462.5500 467.5500 50W 25kHz* RPT16 462.5750 467.5750 50W 25kHz* RPT17 462.6000 467.6000 50W 25kHz* RPT18 462.6250 467.6250 50W 25kHz* RPT19 462.6500 467.6500 50W 25kHz* RPT20 462.6750 467.6750 50W 25kHz* PRT21 462.7000 467.7000 50W 25kHz* RPT22 462.7250 467.7250 50W 25kHz* *Note: 20kHz Authorized Bandwidth.

Will do, thank you!

Thank you!

Being new to this I could quite possibly be doing something wrong. I was scanning channels and picked up the conversation on repeater 21. I used the Wouxun software to program the repeater name and frequencies as RX 462.7000, TX 467.7000 with input tone.

I have a KG 1000 with Tram 6.5 dBd gain fiberglass antenna mounted on a 10 foot steel pole to my chimney, (15 foot high total.) I'm running 75 feet of Messi & Paoloni Ultraflex 7 Premium coax, and at 50 watts I'm reading 1.8 SWR. I can easily hear people talking on a repeater that is 13.79 miles away straight line distance ( granted permission to use.) I am certain I have the correct input tone, but no one can hear me at all. (They are asking if anyone is waiting to jump in so I'm confident they are not ignoring me.) My question is, with 50 watts of transmit power, if I can clearly hear them, should they not be able to receive my transmission?

Exactly, post on a sticky and debate over. I would not discuss it again. Just direct people to the sticky.

That is the problem in my view. With a sticky on the forum, it is set as a basic standard. When anyone asks, you point them to the standard. I have no stake in this but it really is a simple solution that I am amazed has not been done yet.

It would be great if they posted a sticky titled "GMRS Radio Frequency Chart," and just listed channel uses like CB. I would imagine if it was posted on a sticky where a lot of people can view it like on this platform it would stick. Not to mention if anyone asks, you could point to the link.

Fascinating documentary. Favorite quote from Hertz, "I don't think the radio waves I have discovered will have any practical application."

When a repeater owner lists Input and output tones as a number such as 114.8 Hz is that always a CTCSS tone? It is clear when it is listed as 172 DPL, they give you the information that is a Digital Private Line Tone, or DTCS in CHIRP NEXT. It gets more confusing when the output and input tones are different, but not listed as DPL. For instance, Input Tone 114.8, Output Tone 141.3. Is this a CROSS tone in CHIRP? If so, is it TSQL or DTCS? I have researched is but can't find the answer.
