Stoner SSB-20A Follow-Up

8 Comments

After I posted this in January, I wasn’t sure I would ever hear  anything more about it.  But, fortunately, I was recently contacted by Ken KA5KEN, who said he had parts and documentation for the radio.

I was thrilled, and sent him an email.  With some discussion and research, we were able to determine what parts I needed.  So I was able to buy 3 receive channel modules, 3 transmit channel modules, and an assortment of crystals from him for a reasonable price.

My first peek at the parts.

When they arrived in the mail, I could hardly wait to put them to use.  The channel modules were in great shape, and the additional crystals will give me much more freedom in choosing my operating frequency.

With all of the channel modules in place, I turned on the receiver.  All 4 channels worked, though 2 were decidedly more sensitive than the others.  Some adjustments need to be made to “peak” the resonance of those circuits, a routine procedure that I fully expected to be necessary.  And fortunately, I was able to acquire a scanned copy of the SSB-20A technical manual (SSB20A), which explains all of the procedures to properly adjust this radio for maximum performance.  And…I’ll get to that sometime.  The manual reccommends some test equipment I don’t have yet, and I just need some time to collect it or work out how to do without.

I like video games, ham radio, gourmet food, sci-fi and fantasy literature, tabletop gaming, computer programming, cryptography, antique firearms, kung-fu movies, the Blues (music), strange or unusual things, people who know when to shut up, long walks on the beach, and getting caught in the rain.
