Hi,
I have seven of the command receivers in various conditions. Most of
them are useable and the rest will be - except one (number 8) that is
way beyond the pale. A crushed junker. To make them whole again I do
need some sheet metal. Some of it will be easier for me to fabricate
than other pieces but if I can get my hands on original parts in
reasonable condition I'll go that route.
The small metal cover with 5 slide latches that cover the tubes and IF
cans - need 3. This one will be the easiest to fabricate if I can't get
them.
The bottom plate - need 1. This is only slightly harder than the small
top plate. Making and accurately locating all the posts to receive the
screws - time consuming.
The top housing - need 1. This one covers most of the top of the radio
and has the opening for changing tubes where the smaller cover goes. I
could make some kind of a facsimile of this but the folds and radii...
kind tough.
And antenna terminals. Those things get broken (or even replaced with
coax connectors). - need 4.
Anybody can help with any of these please contact me off list. These
bits can be black or bare and I'll deal with that if needed. If your

I have begun evaluating the working radios more closely with antennas,
earphones, and cans connected. I'm using batteries to give me heater
current and B+ (90 volts). I have to pay close attention to the battery
piles. All but my BC-454 have the 24 volt heater strings. That one has
been rewired to 12 volts. I need to put it back the way it is supposed
to be or Murphy will get me. So far the radios I considered were working
radios (regardless of modification) actually do work pretty well. Some
caps need to be replaced (lower B+ helps with that) and they could
generally be prettier. I was playing wuth the BC-455 (40 meters) today
for a while. It took some extra time to warm up and after that it
drifted a little bit but this is one that needs the tube cover. I am
using these with some audio filters that help quite a bit but I turned
the filters off for 40 meter SSB and it did very well.
I got the BC-455 from John Forster, a member of this list. Has anybody
heard anything at all of John recently?
