Just pulled the trigger on a Comet GP-9NC, wish me luck 😅
LeoG replied to SvenMarbles's topic in General Discussion
I just picked up the CA-712EFC and 10 ft doesn't seem that long. Good luck with the beast. -
Did you check your spam folder? It usually takes them more than a couple days to respond. If and when they do you'll see they are in chyna from the time stamp when they sent the email. I have 12 and found another that was dead on output. Took 2 days for them to respond and said they sent a new one. We'll see if it arrives. Also asked if I wanted to try out any new products when they come out. Heck ya... free stuff.

No idea what OS he's using but I doubt it's Win11. When I got my cable I made sure to get the FTDI chip. More expensive but so far it works well on my TDH3 and the Kenwood and all the programs I've used it with, Tidradio, BTECH, Kenwood and Wouxun. But the Wouxun was their own cable.
-
I'll pass this onto him. Thanks.
-
Well you guys were able to help me out with programming a Kenwood and I mentioned that to one of my friends on the 575 and he asked if anyone had the software to program a VHF ICOM IC-F521. Says it's a nice radio and in great shape and he'd rather have a working radio than a paperweight. Figured I'd ask. Thanks again.
-
I told my friend that there was one available on ebay. If he wants a pair of them that would be a good way to go.
-
Condition: For parts or not working And it's VHF which does me no good because the only license I have is GMRS for radio.
-
I'm spoiled with the chynese junk with a digital screen and keypad programming. But this seems like a rugged radio that should last my friend as long as he wants it to.
-
Seems simple enough. The only thing I didn't recognize is the last column "Opt Signal" But it seems to have everything needed. The analog and digital tones are all in one pull down which I haven't seen before. But that makes little to no difference.
-
Works like a charm Lscott. No problems what so ever programming it. Not password protected. In like flynn. Thanks Again.
-
If you didn't blab it on the internet and did that, would anyone ever notice? No. But I believe they meant 50 watts out of the transmitter which no matter if you want to call it an amplifier or transmitter is the main source of the signal going to the antenna without the hair splitting. Need a thousand lawyers to write the regulations and still someone will be able to "interpret" them differently than was implied.
-
Yep, I was gonna say the same thing Steve. Out the back of the amplifier is where the 50 watts is measured. If it's an all in one unit you get to have 50 watts out out of the duplexer if the duplexer is housed in the same case as the amplifier.
-
At that point I'll give the radio back and tell the guy good luck. He got it for free so no loss on anyones part.
-
Well I got the program installed. No radio with me though. Thanks again, hope it works.
-
Doesn't have the K at the end but I'll give it a shot tonight. At worst it won't read it and I delete it off my computer. Thanks.

Anyone know what I need to program this HT? Friend of mine acquired one and would like it reprogrammed to GMRS channels. It's currently programmed on 8 of the 16 channels from 456-467 MHz with mostly digital tones. I tried reading it with various settings in legacy CHIRP with no success. I used my TDH3 to find out what frequency and tones are in there currently.
-
OK, added it up and it came out to 166dB loss. It was 1660 meters of trees. That doesn't include houses that are in the way and the slight hill I'm on, but I think my antenna is up high enough so that isn't a factor. Only if I'm on a hand held. 102 watts is 50.09dBm - 166dB = -115.91dBm Sounds about right the way the signal can act sometimes. The best I've seen is 3/4 on my power meter on the mobile radio. Worst is non existent signal but that's unusual. 1/4 on the power meter is usually as low as it goes. I've never had full quieting on the signal.
-
I stopped calculating at 102dB. There was many more trees patches to go. I basically stopped at 1000 meters of trees. My signal at times can be adequate, but but it varies considerably. I put the squelch up to 4 the other day and my wife couldn't here me during the day. I dropped it back down to 1 to make sure that didn't happen again. According to calculations the input into the antenna after coax losses are 32 watts and the effective radiated power is 102 watts. Let me finish adding up the loss of the trees.
-
At the base of the antenna or at the tip. This question is for when I input the height on the website "Radio Mobile Online" Of course the general knowledge of knowing is a good reason too.
-
Well it came in. The packaging freaked me out a bit. It said 70cm which I know is 440MHz, but it also had a "C" sticker put on the end of the original printed label. I wrote Jim and he assured me it was the correct antenna and said it came that way from the manufacturer. After I got a response from Jim from Chatt Radio I noticed the antenna had a sticker on it saying it was indeed the CA-712EFC antenna On top of that the stated 9.0dBi gain listed on all the websites I've seen but the gain is listed on the package and in the literature as 9.8dBi gain. Not much of a boost. But going from 7.2 to 9.0 vs 7.2 to 9.8 is 1.8 change vs 2.6 additional gain. Nice.
-
I already took your advice. I ordered a Comet 712EFC GMRS 9dBi antenna. It will be here tomorrow. This is for the repeater site. The antenna will eventually be put above the tree line using Messi and Paoloni Hyperflex 13 as I stated above.
-
You should know this already. Repeater at the shop is 50w with 40w out of the duplexer. 50 feet of LMR400 to a Retevis MA-09 7.2dBi gain antenna that is currently at 40' at the base. At the house I have a 20w Wouxun XS-KG20+ that outputs 25w. 84' of Messi and Poaloni Hyperflex 13 cable running into a copy of the 7.2dBi gain antenna at 42 feet off the ground. The shop is 100 ft higher than my house. Sometimes the signal is pretty strong 3/4 of the power meter. Never full quieting. Tonight it's running low, between 1/4 and 5/8 on the power meter. Signal varies, tonight you can watch in swing up and down on the meter sometimes. Most of the times I'm using the repeater with a 2w talkie inside the shop to talk to the little lady. Other times I'm miles from the shop. In the northern direction I can get pretty far but am limited by hilly terrain.

The red line is mine at what I guessed is 462MHz which ends up at 0.1dB/Meter attenuation for tree leaves. Now I see why I have such a big issue with receiving my repeater signal at my house. My antenna height is in the thick of the leaves. 40' high at the base with trees at about 72' tall. I was doing measurement calculations and I stopped when I hit 102dB of attenuation

We can't talk about good looking women on the radio? Guess I'll have to forfeit my license.
