BC-348 Modifications



Four easy modifications that can be added to a BC-348Q to make it a more practical for Ham radio or SWL use, Please note I started with a 348 that was allready modified, if you have a clean unmodified 348 dont change it. Find one that has been hacked! origional examples are hard to come by and shoud be preserved.

Nice power supply look...the S meter and antenna are truly ghastly. To have
Crystal filter working beautifully all else being ok, determine the actual
crystal frequency, not its nominal value and centre IF's to it...NOT tune
IF's to 915 and expect crystal to magically do a job you have just stopped
it from doing. Cheers

Hi Ray, I had 4 of these, some mint some OK. My first rcvr was a BC-224
when I was a Novice. I rack mounted 2 of these on the original shock mount
base which is now quite rare. I restored 3, '348's but I could never get
the S-meter circuit to work ! I had the exact meter that's in yours. And
yes, all my radios suffered from reduced audio output with the Crystal
filter "in". Alas, all my '348's now reside in other collections, one in a
restored B-17 in California. They were great radios, extremely well made. I
own most of the era's "Surplus Conversion" handbooks garnered over the
years and not for sale ! Thanks for posting.

Loved it! Thanks!

There is a drawing of the S meter circuit on my web site on the BC-348
modifications page. The new s meter circuit goes between the feed to the
screen grid of the 2nd IF amplifier and the screen supply, the screen grid
on the amplifier is pin 6. Be careful because high voltage will be on that
point. Ray Fantini

Hi Ray,..I just acquired a BC 348-B..and after doing some "Cleaning" of the
exterior ( it came from a Smokers home) and cleaning up the incoming AC
line ( I added a Computer type Cord/plug) the radio works fine with a small
"Long wire antenna"..can ypou tell me exactly where you tapped the line
into the radio for the "input" for the "S" meter ( Tube, and tube socket
number)..Thank you!!.......Richard KC6VKV Reno, Nevada

I pick up one to way back in 1994-95 for $50 with a little mods with a AC
power supply and I love it and had an ART-13 working with it but the ART-13
bit the dust and have to try to rewire it. Looks like it will be fun to do.

Nice radio. I've got one that's been modified in similar ways for s-meter,
speaker level audio and standard ac power. It works well. I bought it at a
local hamfest. I'll try to do a video in the future.
