How much power does the UHF require on transmit? How noisy is the site? Andy WJ9J

I am looking at options for a remote receiver project (receive on VHF - link to primary transmitter on UHF). The project requires very low power consumption since there is no utility power at the

I wondered what became of Michael, Tom. That answers that! He was always a pleasure to deal with. I haven't been back since he retired & they stopped doing LMR crystals for a while. I've had one rock

Last order I had from Bomar got sent to another town with the same name in a totally different state never to be heard from again, then when they remade the lost order it was sent in two packages for

Guys, Anyone looking for some UHF or microwave parts or components, take a look at the MMARSI.org internet auction site.? Scan down the list of items and you'll come to a group of items that might be

Well, my 2 cents is, Michael retired... that’s when BOMAR went in the trash

Years ago when most ham radios in the FM 2 meter band used crystals, they did not do very well .? They would often drift off frequency and after a while drift too much to be pulled back on

"That was YEARS ago" (my emphasis). See Kevin's message: Bomar is NG now. Bob NO6B

The last two Bomar crystals I got had problems. I never went back. I can't recall exactly when this was, but it was shortly before International went out. International was my last crystal purchase,

I have used many many Bomar crystals over the years and they worked very well, not seen a failure.? Did get one for 6m not on freq, claimed did not calculate base freq out to needed decimal and they

QuartSLab prices for G.E. xtals went up over 70% in just 18 months, & that was as of a month ago. Maybe they went up another 20% since then? Bob NO6B

Years ago I ran a touch-tone function decoder on my Santiago Peak repeater that was fed by pre PL muted audio. No tone at all was required to send it a command. And since it didn't require PL to talk

* Thanks Jeff - but that would mean that normal repeat function would require a tone to get through - correct? Are you saying that you operate the repeater carrier-squelch? If so, then I'd do the

Here is something to think about also that may help. Look at the attached file. Rather than using a CTCSS decoder, I used the COR from the control radio. Mick - W7CAT

What Dan sezs. I've installed this at our main repeater site: https://www.ebay.com/itm/Repeater-Controller-Accessory-automation-Controller-8-Outputs-Relay-driver-DTMF/291330415500

Thanks Jeff - but that would mean that normal repeat function would require a tone to get through - correct? We do not want to do that either. I think from the several suggestions we have, adding

A good number of years ago I was using an RC850 controller and had a 220 MHz receiver feeding it for control.? DTMF never made it to any transmitter. Today you can buy a DTMF decoder for almost

Just use a separate receiver on another frequency and a DTMF controlled relay. There is a good unit that has 8 relays that is advertised in the back of every QST magazine. You can then connect that to
