I had a coworker give me a Kopy Kat amplifier a few years ago. It worked OK, wasn't anything to write home about, but the problem was the method used to convert 12v dc to the higher voltages needed for the tubes produced a very loud and annoying audible squeal. The only way to keep the squeal...

Glad to help

You guys are paying too much :tt2: Check here: SEMICONDUCTOR 2SC2166 - Electronix Online - Computer and Electronic Parts and Supplies Been dealing with this company for years. Always had good service and fast shipping. Never had a DOA part from them yet.

I too am now seeing a 'Hello' message at the left side of the screen. It looks like they may have had a server crash. Earlier today CBtricks was displaying the default apache server message saying everything was installed correctly. Hopefully they're restoring from a backup and will be...

Update 12.14.10 2240CST SOLVED: Q54 was the culprit.. a 2sc945 transistor.

I have a RCI 2950 (Old Style Non DX) that is not working properly on AM. SSB works fine, but when the radio is placed into AM Mode, the radio deadkeys around 30 watts and I have no modulation. I replaced the 2SB754 AM regulator with a brand new one I had in my parts bin. It did not...

Last week I caught a RCI-2950 on Ebay for $125 shipped buy it now. I decided to go with that in the mobile since I've always been happy with the 2950 I already own. It arrived today, and I decided to hook it up just to do a quick power test before I take it out to the shop and put it on the...

Replace D1 and D2 in those radios and they'll be good to go again. When you're close talking in the quarry, start running with the RF gain backed down.

LAST ONE: I have listed the last Cobra HH45WX Handheld CB Radio I have on Ebay this evening. This one is identical to the one that I sold a couple of weeks ago. It has the same modification that gives 40 upper and 40 lower channels in addition to the normal 40 channels. Comes with brand new...

Bump.... ending today

What is your radio doing, or not doing?

SRF puts the meter in Signal / RF Output (Transmit) mode. In that position, the meter will show the signal strength of incoming transmissions and it will also show you the relative signal strength of your outgoing transmissions.

I have just finished listing this week's items on Ebay. First off, I have listed a Uniden PC68XL CB Radio. This radio has had the Mosfet installed and I'm showing around 45 watts peak on my HP5000 meter. The channel display and meter light have been replaced with blue LEDs. I have also...

Last week I picked up a nice President Grant DX ( Dual Final Export ) Everything works as it should, and the original owner had modified some of the front switches for different features such as a 10kc switch, high/low power. NB/ANL & Roger beep switches are untouched. This evening I...

For the vintage electronics / maritime collectors here I picked this up last week and have tested it to the best of my ability. I do not have much experience with Radio direction finders, but from the limited knowledge I do have, this appears to be working 100% correctly. My best guess...

Tony, The HH45WX as well as the midland counterpart... i think the 75-822 or something similiar both take a channel modification. A few years ago when I had a shop open I came across a good deal on a bunch of these. I picked them up and they were an instant hit with the hunters around...

Tonight I listed a Cobra 45wx Handheld CB Radio on Ebay. This has had the channel modification performed and now has the normal 40 channels, plus 40 upper channels, and 40 lower channels. Frequency coverage is around 26.515-27.855MHz and is inline with the export bands. The original antenna...
