Thread bump (and I haven't been on here for a while anyway): On CB - Either a CPI CP-2000/BC-2000, Pro-40 or TRS Challenger 1200/1400. Rotate them in and out from time to time. Scanning/monitoring: Probably 30 different receivers running concurrently, all PC controlled. Multiples of Optocom...

How are the electrolytics going to affect adjacent channel rejection? This is clearly an IF filter problem. More to the point, leakage around an already marginal filter.

Once upon a time I used to love hanging around Ch36-40 - you could always find a group of SSBers in that area, even when there was no skip to speak of. Yes, that "day after day" shtick gets real old, real fast. Maybe the Class D service will get popular again and people will start...

PLL going out of lock on these rigs will cause the symptoms you describe. Loose harness connectors or intermittent Molexes (which join the VCO and PLL boards together) account for about 90% of '820 PLL problems. In the case of the Molex connectors, DeOxIt can be used with varying degrees of...

I'm a bit late to the party but here goes: In the fall of 2010 we had a new XV95 installed. When I turned the HF radios on and the furnace kicked on for the first time...S-9+ noise that the rigs' blankers wouldn't even touch. I had to engineer a solution independently of Trane's, and the one...

What you did there...

My faves are the CPI line, SBE LCB8/LCBS4/8 (still looking for a good example of each) and the HyGain 623. CPI's receivers are second to none with regards to its CB competition. A/B switching tests between my base set and a number of higher-end ham rigs in the shack show the CP2000 to be very...

Some of those clubs' nets were to CB what a lot of over-structured, formal traffic nets are to amateur radio: No place I want to be. As far as the list of unmentionables goes...head thee to a couple select frequencies in the 20M band and ask the inhabitants thereof just how well that...

I currently have 624 (23ch) and 625 (40ch) AM-only base units, a 641 and 642 base and a pair of 639s - along with a few other accessories such as the desk mic. One thing to keep in mind about these rigs: They're single-conversion and the receivers are subject to image interference from SWBC...

The timebase oscillator crystal is bad. I recently repaired an FC-70 which exhibited the same symptoms. Do you have an oscilloscope which can be used to check the reference oscillator? If this is the problem, you'll see a gradual decrease in oscillator signal amplitude at the input of the...

Unmodified Cobra 139XLR (858 chip), stock hand mic and Dynamike power desk mic for sale. Works as it should - 4w AM/12w PEP SSB. Equipment is in very good shape with a few minor wear marks. $110 shipped to your door. I have a few higher-res pics that I'll send to interested buyers. Reach me...

I've gotten a number of good deals at hamfests over the years. Minor adjustments or repairs don't bother me, as everything's going to need attention at some point in its life. That being said, sellers should state up front any "issues" with the gear they're selling. Word does get around WRT the...

Let me see what she has and I'll put 'em up. Missed getting a pic of "antenna-hair girl", however...

The big line of thunderstorms which moved across PA on Friday afternoon and evening served to charge up the E layer...was getting lots of 2-land skip on 11, 10 and 6 here in Ohio.

What killed our Field Day is the loss of a good operating spot. My father in law died last year, and their 3+ acres were open all around...ringed with tall trees. It was a beautiful setup for low-band antenna erection - but too much work for his widow to look after. Her new digs are more "towny"...
