Bill’s Bench:
The 15-10 Dual Bander.
10 pole crystal filter at 25 MHz.
G3UUR, Dishal, AADE and all that..
Testing woes. Looked bad. But it was a bad test cable. Duh.
VFO (Colpitts) at around 3.5 MHz.
Buffer blues: Bad J-310s. Beware!
Variable cap from a Heath Q Multiplier
A bit of a black art – competing goals. Freq coverage, etc.
BFO needed an amp to turn on the diodes in the balanced modulator
TIA amps. SIX dual direction TIAs. 18 transistors.
On a pine board (like Frank Jones)
Will use the N6QW all discrete AF amp.
Maybe an RD16 in the final?
Will build a second one for the DR.
Shameless Commerce: Mostly DIY RF and the PSSST kit. Todd K7TFC reports: “The P3ST is on track for Lee Deforest's birthday release (August 26th). I'm going to send out another newsletter on July 4th, and I'll give some details on P3ST development.” Results of Todd’s Survey.
