What happened to the BC348 restoration? I have one and would like to restore it.
I would say that Mr. C has so many things going on at the same time, it’s difficult to know what should take the priority. I can’t imagine when Paul finds time to sleep or just be with his family. I too was enjoying the restoration series, but I was delighted when the Ultra Probe was announced. I’m sure Paul will get round to it whenever he’s able too.

I am sure Paul has a family life also and now with the forum, YouTube, and Patreon.
I believe Paul need a vacation too.
Make videos really take a lot of time, as I have tried myself.
I am still getting question from folks asking questions from some of my postings.
One thing for sure he will have more coming.
Now PAUL, when is the “BC348 restoration” coming? just kidding and have a cup of coffee and get back to what you was doing.
I do have to say, he looks at the response to the YouTube video for interest to see what he should do.
He is always watching the comments, like other constant providers.

Back in the day, just before i got my novice HAM license (1961), dad (also a HAM) gave me a BC-348 that he had acquired from the Air Force MARS program. Of course, it did not work, but because I was told to keep my grubby mitts off of his Collins station, I was left to my 13-14 year old wits to repair it. I was actually successful after 2-3 months of wrangling with it and its schematic. The problem was a shorted bathtub cap in the B+ rail to the plate of one of the IF amp tubes (diagnosed from the schematic and a lot of VTVM measurements). Sounds simple, but to replace this cap, which was located inside one if the enclosed/shielded IF compartments that also housed the associated ceramic band switch wafer and coils, the the receiver had to be partially disassembled. In removing the defective compartment, I broke the darned wafer into two pieces while trying to remove the IF compartment and so I had to utilize some early teen smarts to put the two halves back together and secure them (a piece of bare wire wrapped around the wafer’s periphery and tightened — hey, it worked).
After building an external power supply, I used this receiver while learning the code, and for the next couple of years after getting my general ticket. Still have it in my store of vintage equipment.
My BC-348 was a lot of fun, but I still remember what a real pain in the backside this equipment was to work on. I repaired and put an ART-13 on the air as well when i got my general (I still have it as well, and three others in my warehouse). It, too, was not for the timid to work on.
Mr. Carlson, you got my best wishes and full encouragement as you restore these two fine pieces of military vintage gear. These units can be frustrating to work in, but if a grubby 13 year old could do it… (heh, heh, heh)! I look forward to your videos as you work your way through these. Brings back a lot of fine 60+ year old memories.
