Lol yeah... some people think it's crazy that I use something like a rubidium oscillator to monitor and calibrate an old Heathkit counter like that.

For the record, the model is an IB-1103. It measures up to 180 Mhz. This counter has a TCXO (temperature controlled crystal oscillator) in it, so once it's warmed up (about 20 minutes) it's remarkably stable. Picked it up at a flea market for 10 bucks with the manual. Had a friend of mine have a look at it, (he's extra class ham) and he was amazed at how accurate it was. All the nixie tubes are functional, everything works as it should. If anyone would want to start getting into repair, I'd highly recommend getting one of these counters.

Robb,

I got the rubidium oscillator from a friend of mine that was experimenting with them a while ago. He told me that they were very accurate and would work great for calibrating radios and counters. So I got one from him, and custom built a power supply for it. Yeah, it's overkill for what I use it for (CB band stuff) but it was cheap and it works good.

~Cheers~
