Bob KD4EBM recently sent me an amazing package of radio goodies. Included was a little metal box not much larger than a deck of cards. It is a 20 meter SST transceiver designed by Wayne Burdick N6KR during the late 1990s. This transceiver is built around three NE602 Gilbert Cell mixer chips. It arrived in my shack as I was struggling to understand the Gilbert Cell. TRGHS. It also put me back on the path of QRP CW righteousness. Thanks Bob. Thanks Wayne. <\/b><\/div>\n

<\/b><\/div>\n
I e-mailed Wayne Burdick (now of Elecraft fame) to tell him I was now using the rig he had designed so long ago. Wayne e-mailed back, saying that the SST was the smallest “real” radio that he had ever designed. SST stands for Simple Superhet Transceiver<\/i>. <\/b><\/div>\n

<\/b><\/div>\n
I’ve been using the SST every day for the last week or so. It is a pleasure to operate. I’m using it with the key from India that Farhan brought for me. It is truly QSK — the receiver stays on when I transmit. I’ve never used a QSK rig before and I can now see the big advantage that this provides: When I am responding to a CQ, I can immediately hear if the other guy put out another CQ or respond to someone else — I can stop calling at that point. <\/b>My first contact with it was with F6EJN. Again, TRGHS. <\/b><\/div>\n

<\/b><\/div>\n
I made two small mods to the SST: I added 1 uH to the RFC in the VXO; it now tunes 14.053 — 14.063. And I took out a noise blanker that had been installed. Removing the noise blanker left an ugly hole in the front panel which I promptly filled with a completely cosmetic machine screw. <\/b><\/div>\n
