[Milsurplus] RBA, RBB, and RBC - $150 - ending real soon

[Jim Hill]

I have all three, too.
Local RFI is too bad to use the RBA, but the other two are nice 
receivers.  I had a few out of tolerance resistors, plus a bad mica 
capacitor.  Two gotchas that I remember - the machine screws securing 
the leads to a the RF coil assemblies are a little shorter than 
others,  If you accidentally use one of the other screws, they bottom 
out.  If you notice a loose connection and tighten the screw a little 
more, the ceramic standoff can be broken.  Also when you are 
adjusting the slugs in the RF coils and go clear to one end, be very 
careful when using a screwdriver to move it in the other 
direction.  The slug may jam, and It's easy to break off one side of 
the adjustment slot.  Fortunately, I managed to get a parts receiver, 
think it is a RBB.  A coax "barrel"  UHF adapter can be pushed into 
the odd-ball antenna connector, making a nice Navy to UHF adapter.  A 
banana pin pushed into the center hole of the barrel makes a nice 
connection to a wire.

I need a dial glass for the RBA, if anyone has a RBA parts receiver.

I have a question.  When using a random wire antenna, I never was 
able to adjust the receiver antenna coil so the trimmer worked across 
the band.  Have any of you experienced this problem?
