Re: Motorola XPR8300 repeater, no USB comms
Also to look at, is replacing the front display board (with the front panel LEDS) which affects both the USB and LAN connectivity. I've had to replace a number of these in the past on different

Re: ID-O-Matic IV Controller setup with Kenwood TKR-850
I'm presently working on a TKR-750 now on the bench. That is the VHF cousin of the TKR-850. In the KPG-91D software you want to go to EDIT> FUNCTION PORT and select the AUX tab. I used the "AUX In/Out

Re: ID-O-Matic IV Controller setup with Kenwood TKR-850
Piotr, I would suggest that you use the TOR signal for your COS input to the controller.? It is a combination of COR and CTCSS, so you get the benefit of a slight delay (settable in the radio code

I would be interested in the PA only I could use it for a spare for my 6meter repeater. What would you want for it. Mike W1ZFB

Re: Why use a purpose built repeater box as a repeater rather than a transmitter, receiver, and controller tied (lashed) together?
Motorola service bulletin specifically stated that for 100% duty cycle operation the R1225 High power repeater models were to be set to operate at 25 watts max. output from the transmitter, not from

ID-O-Matic IV Controller setup with Kenwood TKR-850
Does anyone have any experience setting ID-O-Matic controller. I have trouble getting my to work with Kenwood TKR 850 repeater.

I ahve an IC20 and a few IC22As. Looking at the spectral output of the IC22, it is very clean. I was impressed enough to keep a few for our club's repeaters. It also has helicals ahead of the rcvr.

Adam Farson VA7OJ gives an interesting method of phase noise testing of HF receivers with his NPR method . https://www.ab4oj.com/test/main.html#NPR

Re: Low Band Motorola Base
If it's on 45mhz then it can go to 6 meters.? Crystals are available from Quartzlab. Are there any modules hiding behind the test set?? (the speaker assembly) I supect the cards include a squelch

Re: Why use a purpose built repeater box as a repeater rather than a transmitter, receiver, and controller tied (lashed) together?
What exactly are you trying to accomplish? If the notch filter effectively gets rid of the noise generated from the rouge transmitter, what more do you need? I presume the BpBr can Bob spoke of would

Re: Why use a purpose built repeater box as a repeater rather than a transmitter, receiver, and controller tied (lashed) together?
What is the standard method to measure phase noise? Most measurement systems have pretty wide skirts that seem to be phase noise generated by themself, not actual phase noise from the transmitter.

Thanks for the graph Bob. Kenwood looks nice ? ________________________________ Sent: Sunday, January 17, 2021 11:31 PM To: [email protected] <[email protected]> Subject: Re:

Yes, the "intermittent duty" heat sink was a lot like the MOCOM. But not quite.

Re: Why use a purpose built repeater box as a repeater rather than a transmitter, receiver, and controller tied (lashed) together?
What would've worked better in that situation is a pass-notch cavity from a duplexer. I've been lucky enough to find a couple standalone BpBr cans at Dayton & local swap meets. While designed for 3 or

Re: Why use a purpose built repeater box as a repeater rather than a transmitter, receiver, and controller tied (lashed) together?
Not unless you're talking about the PLL G.E. exciter. In the offset frequency range of 12 kHz to 3 MHz a Kenwood TK-880 mobile has lower phase noise, as much as 20 dB lower at some offsets. Bob NO6B

There are reasons why a repeater like a Quantar cost >$10,000.00. A clean transmitter is one.? I have run a Quantar on 2 meters at 600 kHz split? with no desense on an 80 dB 4 can duplexer.
