This particular 3 digit LED was salvaged from an old Kidde Nighthawk carbon monoxide alarm. Most of these carbon monoxide alarms start to signal “error” after about 3 or 4 years and need to be replaced, but IMO the LED readout is worth saving for various projects. I modified the following...

The Hygain 3077 is the first version of the Hygain 7 series (crystal matrix board). Although they're similar, there's 3 of them. The 3107 is the latest 02A PLL version. RV2 on page 2 of the pg21 - pg43 pdf is the modulation adjustment. Be sure to make a note of all the screw locations and the...

Spot on! Be very careful if you decide to test for heat with your finger on that back transistor. I had a customer burn her finger while she was removing that Pace. We never sold those, but only had taken a few of them in for parts on a trade deal. I remember trying to modify one using the push...

I recently screen captured this CB radio from the movie “Death Race.” The Hallicrafters Littlefone CB-3A was a popular 8 channel radio made back in 1962. I recall repairing and wiring a D104 desk mic to one of these for a friend.

I can’t remember what particular mic that I applied this mod to years ago. Anyway, I removed the existing contact assemble, and replaced it with a set of similar long bladed contacts taken from and old telephone relay. Those typically had stacks of multiple NO and NC contacts. I removed the...

Google turned up this location. Mike's Cb Sales & Service (920) 490-7640 2050 Marlee Ln Green Bay, WI 54304 Photo shows this is a ranch home in a residential area with no antenna in sight. Who knows?

Agreed..I replace them with an electrolytic only as a temporary solution, usually when I don’t have an exact replacement in stock. For the time being I wouldn’t worry too much about the stability of an AM only radio. It’s not SSB where drift needs to be kept to a minimum.

IMO There is a list of things that need to be done first to that radio. The corrosive glue needs to be removed. All the electrolytic caps need to be changed. Besides a thorough visual inspection, the glue and caps should all be taken care of before the power is employed. A new power plug and...

Did you try keying another radio nearby on the same channel to see if you get a meter deflection?

A modified version of a comic I saw on the web. A “caveat emptor” warning that should apply to anyone seeking an honest and reliable repairman. I may make some additional changes at a later date....Possible QSL card....LOL

Interesting post! I just had to research that behemoth a little further.. This is just a few links about the Rugby station's tuning inductor...

Tom tried to follow and be cool, but I think Janis schooled him with her energetic action.

I found the content of WBCQ “The Planet” to be a very diverse. Nowadays, I ‘m not enthused to listen very long with shortwave broadcasts that often fade with audio distortion. Unlike collecting QSL conformations like I did in my youth, I’m now interested only in their content. After looking at...

I noticed that CBtricks has a rather poor copy of Sam’s #207 for that radio. I have that book and will post a better version when time allows.

A lot of the older Bearcat scanners were plagued with corrosive glue. If you’re Bearcat has that glue, you will see it around and under some of the larger electrolytic caps, crystals etc. It needs to be removed ASAP, and that includes changing most of those components associated with it. My...

I got a little teary eyed....

I've seen several Surveyor radios in the past. This one is entirely a different animal. As seen in the photo, all of the electrolytic caps were changed except the large blue 1000uF cap next to the audio IC. I was concerned about that issue, but that one has been replaced since the arrival of...
