This page will hopefully fill the void on the web on Amateur Conversion (or attempts thereof) of ARC-5 & SCR-274N hardware.
This is what I got at the CMRA Pomona swapmeet on 1/20/01. The reciever is a BC-455-B (6-9 Mhz) and the little runt next to it is a BC-357-P beacon receiver, or the remains thereof.
Ahh yes, the leaking green funky stuff. AHH! I'm melting! Since this is going to be my main 40M receiver, (if I wasn't so distracted from practicing my code!!!) I plan to pull the bathtubs and install nice tiny caps.
The tag says, and was sold to me under the impression that it is a CBY 52209, 4 to 5.3 Mhz, but it appears to be modified to do 3-4 Mhz! Even has a 3500 kc xtal in it. Perhaps I lucked out! Need to get that license upgrade, then I'll let myself work on it!
As you can see, a 12a6 is missing, and someone slapped on an outboard 12au7.
OK, this BC455B doesn't count as a whole radio, more like 1/4! Who could say no for $2?
Obviously this one has had a rather hard life! But look, the bottom is intact, this one may run again someday!
Much work to do here... Must.. practice.. code!!!
