I am so angry.  Another miss-consumption of time to reminisce, deleted and sent a copy of Bob’s letter by mistake. Aargh!  Not in draft file, anywhere.

Anyway, I try again —  

I became W6TFE almost solely to legally experiment W/X-band and UHF pulse.  I did manage a one sentence communication atop the pass above Santa Barbara W/friend in S.B. (Field day ca 1954)   before the transmitted drifted.  (420 MHz-except we called it cps)   I had purchased an APS 13  (IFF) for this. (Dual 6J6s W/pulse transformer; receiver ~ one µV. sensitivity after IF transformers retuned to narrow BW.)  My transmitter used door knob tubes — still have!  I may have the modulator;  6L6s ?   


Later during the IGY (1957/58) I purchased a bunch of APS 13s  for my bosses large area cosmic ray detector.  


Detail:  Two 5” MPTs in coincidence looking at a 20gal? soup caldron for Cherenkov detection;  six? in a circle ~ one mile in diameter.  My suggestion, he was going to use cable, perhaps not practical W/O line amps.   Anyway it worked.  Collected data for probably half a year.  I moved on to another project, and a friend continued the maintenance.  


bc …. can also reminisce.
