Did you measure the voltage at the PA transistor? I'd look at that first. Also measure the exciter output and see what it's doing. If I recall correctly, the repeater uses a relay to switch in and out

Hi Group, I have a TKR-851 that I thought had bad finals. It had about 2 watts output. Installed a new transmitter board with new driver and final transistors and now I get 3 Watts output. If I drop

Hello Jared, I have not been following these threads very carefully, but the thought occurred to me wondering if your transmitter might have spurs when connected to the duplexer? It would be easy

So last night, I measured the MTR at 0.4uV at the receiver port and 0.5uV at the duplexer antenna port. I injected a signal into the receiver port of the MTR that had just barely had no noise and when

Hi guys, Taxing the brain, With XP, one had to mod the registry to go back to the bios for the disk driver if the motherboard IDE or SATA driver changes. Then at first boot on the new hardware, it

I asked the seller which version of Ghost he was providing as I was looking for 7 or later. He replied "I think this is version 3 or older, Not what you are looking for." But thanks for the

Here is a link to a program called PiTone which can be used to create a CTCSS tone.? PiTone runs on a Raspberry Pi (can be the same one that is running Allstar).? It uses a D/A converter connected

Jared, We need to quantify why (and when) the repeater is "deaf". Next time you're at the site, do the following: 1 - Disconnect the repeater from the duplexer. 2 - Connect the repeater antenna to the

Hey, we are all human :) -- - Regards, Karl Shoemaker To contact me, please visit SRG's web site at http://www.srgclub.org for the current email address.

I think we need to redefine 'deaf'. What are the current 12dB SINAD 1) at the receiver port, and 2) at the antenna port of the duplexer? (Those values were previously reported as 0.40 and 0.53 uV

Sounds like your forcing that duplexer outside it's parameter. Millin

So the transmit side cavities all have 29db-32db of return loss at pass frequency, 30db of notch rejection and 0.4db of IL at the pass frequencies. I went to the receive cavity causing trouble and

I am not using a repeater. Just using vara fm and winlink. Will be using a cdm1250. Just looking for information on the software side. Sorry for stirring the pot Sent from AT&T Yahoo Mail on Android

I know it has been proposed but I use https://gparted.org/liveusb.php it works on any pc, 32 bit or 64. And if you plug a MAC SATA disk into an external drive bay it will even make a nice image of it

Ok...I obviously missed the data part lol... Chris WB5ITT

Correct, we're not talking about repeaters here. We are taking discriminator audio to the sound card interface for decoding, and sending modulated data from the sound card to the modulator. Obviously

Your pic appears to be a UHF loop. Measuring one out of a 10" UHF cavity I have here, from the loop plate to the bottom of the loop is about 1.05" (about 1-1/16"), outside width of the loop is about

He’s using the radio for Winlink/VaraFM, not a repeater. Data, not voice. Sent: Tuesday, November 1, 2022 1:29 PM To: [email protected] Subject: Re: [repeater-builder] Windows 7 config I

I strongly disagree Scott... That's a recipe for disaster. Feeding wide band unsquelched noise to a modulator will cause the transmitter to over deviate. Remember the squelch noise out of a
