[Milsurplus] BC-653

[Bruce Gentry]

I have no idea of what Tom Kneitel meant by "tuning units", but there 
are plenty knobs and adjustments. Most of them can be ignored if you 
don't need preset operation. I have two of these that have been through 
the mill, and want to make one good one from them. If anyone has the 
small panel with the tuning knob and counters they can part with, it's 
the main thing missing that I need to proceed.  Both of the dynamotors I 
have for the receiver and transmitter are 14 volt, I want to find the 24 
volt versions.  Some of the comments oin the book  are definately 
overboard, but I will agree with him in general about an unmodified 
BC-640. I can attest they will cause serious interference to low band 
VHF television and FM receivers within several hundred feet of them. I 
have heard of shielding and bypassing modifications that reduce the 
interference dramatically to tolerable levels, but have never seen one 
and can't say if that is accurate.

I would have borrowed some text from another one of his summaries to pseudo-authoritatively state, "The designers  of the SCR-506 suffered heart attacks when they received a TCS for comparison."Me, i put away my foolish dreams of  owning one. I have enough really cool looking gear that doesn't require serious thought before moving it.I'll leave this honey to the heavy metal heads.-Hue
