I figured we had a high split duplexer since it was originally purchased for a commercial VHF system. It's odd that one cavity tunes up just fine but the other doesn't. I'm going to try and slapping

Anybody interested in a six-channel GE Master II voter? I have one complete that I'll be putting up for auction on hamradioauctions.com but thought I'd offer it here first. PM me if interested Chris

Tin plating was one of the biggest recalls with micor and later radios.? You could order contacts in bulk and replace them as needed.? Big job.? For some radios they came up with gold plated

I've found that different radios respond differently to high noise levels: some will blow squelch, requiring you to turn up the squelch to the point that once you get away from the noise source, it

My 2 meter repeater is on 147.015MHz. It's output frequency is close enough to a microprocessors multiple of 1MHz, such as 147.000, that users occasionally have problems hearing the repeater. It

This happens to me on 6 meters many times when I am near a new style stoplight. The noise shows up on my S-meter indicator as full scale, but no audio and the squelch does not open. It appears that

Bingo! That's one of the sources. Fire Departments used to complain that they could not hear dispatch when near a stoplight. I am forced to keep my 6-M mobile in tone squelch due to all the noise that

The Delta I used as mobile for a while had a noise blanker that did not help at all. The noise I'm talking about is continuous - coming from POS terminals, routers, DSL, LED sign boards and lighting,

Depends on the noise blanker... My 30+ years of low band FM experience found that some noise blankers work better than others.. The lowband Motorola Micor "extender" had a bad habit of breaking into

I've operated a 6-meter repeater for a couple decades. The thing I've learned is that noise generated near the receiver will desense it a lot. 6-meters now has a LOT of noise sources that were not

I'm curious as to how the above frequencies & deviations were arrived at. Are they supposed to approximate the occupied BW when human speech is the modulating source? This generally does not apply in

My own radio (TH-9800), & observing that while I could kerchunk the repeater all over the place, that's all I could do. It had to be full scale & then some & I had to use 50 watts to get through while

Yeah we'd be much better off with a wider split on 6. I only found one 6 meter repeater in SLC: it had a 1 MHz split & so much desense that it was unusable. Bob NO6B I run one of the 6 Meter repeaters

Hi to All, We have many Motorola MSR2000 VHF, UHF and cross-Band RX VHF TX UHF station still on the air and they have a common Molex plug intermittence on the audio and control card's. Every couple of

pole/surrounding metal, and proper address these issues and have stub or radiator will are not done. I've heard this one before... as if the J antenna somehow is uniquely susceptible to such

Slick would certainly know
