holds 5 of them, one goes in the radio and the other three are in a National 
wooden coil box). The whole thing except the power supply is currently in an 
ex-Altec dark green desktop rack cabinet. Thie radio has been repainted with a 
number of unoriginal holes filled in. The paint job was done with Krylon and is 
a bit heavy. But the overall look of the radio is pretty good. The speaker was 
re‑coned by Jackson speaker service. The s-mater glass is missing and the meter 
vane needs straightened but the meter works. I restored the power supply and it 
is working as designed. The receiver itself has not been touched and is 
untested. With original of newer HRO manual and Photocopy of older style. $435

Curtis KB-4200  Morse Keyboard. This is the grand-daddy of them all. It’s 
1974-vintage and I believe it is the first commercial morse Keyboard. The later 
more keyboards all started out using the Curtis chip set. Selectable speed, 
buffer memory, etc. Looks great. It appears to work, but I can’t get it to play 
a sidetone. With original sales brochure--I was never able to find the manual. 
I beliebe these are rare. I have never seen another one on the Internet or 
elsewhere. $99

radios covering 0.5-4mc and 4-30mc respectively. Made by RCA dream team. With 
one matching power supply, 2 cables to go from supply to radios and original AC 
power cable. With original RBB and RBC manuals 
and copy of Coupling Kit CN-10563 manual for panadaptor (not included). Both 
radios and the supply are in very sharp original condition, with all internal 
covers and all tubes uncluding the goofy ballast tube. Cosmetically, these are 
very good with some paint chipping around the panel edges and small scrapes 
here and there. The knobs are somewhat faded. Both the cabinets and the radios 
have their original tags and the cabinet s/n’s match the radio s/n’s. I have a 
bunch of spare metal tubes to go with these and a few odds and ends spare 
parts. $849 for everything. I would separate them for an excellent offer. 
Prefer pickup in Pittsburgh PA but I will ship them for the actual shipping 
cost. Shipping may take as long as 20 days due to my busy schedule.
 
GWE III AM Transmitter. This is in a 5 foot wooden rack--very pretty with many 
matching meters. It uses plug-in coils and puts about about 120 watts. This 
seemed to be working perfectly when I bought it but then discovered a strong 
parasitic in the exciter. This was fixed and the TX tests out good on 40 
meters. No other bands were tested. Needs AC power rewired using 3-conductor 
grounded line. It could also use new HV connectors for safety. It was all built 
and/or modified by N3GWE, Ed Mantick. It was purchased by me in September, 2002 
after Ed needed to sell it due to the onset of health problems.
Final: 812
Exciter: 6AG7’s driving 807s
Modulator: 45s driving 809s
Power Supplies: Solid State.
N3GWE Modified Eico 722 VFO notes: Modifications include 6AH6 in place of 6AU6 
and power supply changed to full wave rectifier using a better transformer. 
Repainted nicely with black case. Looks good. Knobs are not original. Working 
perfectly and quite stable after 20 minutes. 
--Ed’s original documentation goes with it. This uses Ed’s modified Eico 722 
VFO. This rig uses plug-in coils and a full set is included. Asking: $425 with 
coils and modified Eico 722
 
Thanks for looking.
73, Don Merz, N3RHT
