Vxr-7000, change serial number in CE27 software
We have multiple vxr-7000 repeaters in use, and I kludged one up. I suspect I did a download, rather than an upload, and installed a config file, including the serial number from a second repeater. Is

Re: Sinclair R-302C duplexer info
When I got started the high notch was out of tune. I went back and put it back to original frequencies and got -69 and -65db notches. On the new frequencies it is -62db you are probably right about

Re: QUANTAR VHF Audio Interface...
Yes, Burt, I also agree with that concept because it is better in those circumstances of low initial audio and to me it also makes sense to increase intelligibility when you are receiving noise on the

jb, I want to assure you that WA6TDD was not that way when I ran it.? Once it started to turn in that direction I tried my best to clean it up.? When that failed I took it off the air and others

Re: QUANTAR VHF Audio Interface...
My point is, where is the energy above 3Khz comming from? Unless it is background music or road noise. Sibilance. The hand mics with many Yaesu VHF/UHF mobiles, and their newer HT¡¯s, have quite a

Re: QUANTAR VHF Audio Interface...
John, I personally do not believe in the 5 kHz in and 5 kHz out thinking.? A part of the problem is that stations with low deviation will come through with low deviation and those with high deviation

Re: Repeater Horror Stories
On a 'news gathering link' service I assisted running, basically a 150KHz wide FM repeater we found a pirate station trying to use it. We had remote control of the settings and when not using it

Re: QUANTAR VHF Audio Interface...
Flat audio really means no de-emphasis in the RCVR being coupled to the TX with no pre-emphasis. Hopefully with less processing. Of course on a PM radio vs. a FM modulator means something different. A

Re: QUANTAR VHF Audio Interface...
Literally hundreds of 440 repeaters in this area have audio responses approaching 6 kHz, & no one has had to modify their RXs to hear them. Much above, actually. The last squel

Re: QUANTAR VHF Audio Interface...
On the GE MASTR PRO, there are a couple of capacitors you need to remove to get the perfectly audio flat. This applies to the MASTR imperial as well. The caps are C-16 and optionally, C-21. Andy

Re: QUANTAR VHF Audio Interface...
I agree with you, Bob, that most important of anything is a post limiter filter that will roll off as steeply as practical above 3KHz, with a sharp knee so that below say 2800 is not affected. Seems

Re: QUANTAR VHF Audio Interface...
The above two paragraphs contradict each other: if the spectral energy above 3 kHz is "QUITE low", then that spectrum will not be deviating the TX anywhere near 5 kHz, hence the BW will not be

Re: QUANTAR VHF Audio Interface...
I'm 59 & my hearing is fine, yet I also prefer to go higher than 3 kHz on my repeat audio. I maintain several XPR8300/8400 repeaters set to flat unsquelch audio to give them the best frequency

Re: QUANTAR VHF Audio Interface...
Hi Chris, Thanks for your comments and observations. On my repeater... no, I don't run the audio out to 5 kHz, but at the same time I don't have the sharp 2.5 or 3 kHz cutoff that many systems have.?
