The Collins KWM-1 is the first amateur band transceiver designed for mobile and fixed station applications. Final amplifier plate input power is 175 watts PEP on SSB or 160 watts on CW. A crystal plug-in unit allows for the selection of ten crystal positions, each covering a 100 kc segment in the frequency range of 14 to 30 Mc. NO 40 and 80 meters,    The Pi-L output network with roller-inductor provides for efficient and continuous tuning throughout the entire frequency range of operation.  This Radio was Rumored to be used in the U2 that Gary Powers was shot down in.

a little additional personal info,    here is kŘip using his KWM-1 in 1970 was HS6ADE , Thailand .  Your webmaster !!!!  in the store room at the Takhli  PMEL building. a note,  by the 1970's  these were considered almost junk,  an all tube relic from the 50's and 60's.   so it did pay much.  I sure wish I still had my radio.

Central Electronics  20 A  ,   First band switched SSB radio..  the predecessor was the 10B  it used plug in coils to change bands,     the was a Phasing SSB exciter  ,   20 watts out, ,   Webmasters note, this was my transmitter after I graduated from Novice to General,   A nice radio.   I worked lots of DX on the 20 watts and a hy-gain 14AVQ vertical  


this radio did not have a built in power supply it was extra,    $240 in 1966 is $1838 in 2018..    Who says Ham Radio is Expensive in the 2000's  ,  its cheap

The Mohican
was Heath's first all transistor general coverage shortwave and broadcast receiver. Intended primarily for the short-wave listener and for portability.  covered the AM broadcast band to 32 mHz.
it includes calibrated bandspread for the ham bands and a BFO
for copying code and SSB

in 1965 this cost $90, and the  accessory 120VAC 
supply was another $10   
in 2018 dollars $800 !! 
and you think Ham Radio is expensive now.

and a Desk that didn't come from Ikea
ARC-5 receiver, WW2,  used in most fighter aircraft like the corsair's, P51's  and almost every aircraft in the inventory.  These and the matching transmitters, they did the job, there had to be millions made,  because every HAM  in the 1950's had at least one, and several of the  transmitters,

The one pictured here,  was made for connection to a Direction Finding LOOP ,  
most receivers  only had one antenna jack..  The receivers used a flexible cable, like an old speedometer
cable for remote tuning from the cockpit,  the transmitters were set to frequency before a mission.
