[HBR] RE: HBR 2006 and a question

[windy10605 at juno.com]

Apparently the HBR was the right receiver at the right time judging from
all the people who built them and the interest which remains today. It
allowed home builders to try a "more complex" design and come up with
something which was really useful for day to day operation vs being put
on the shelf. Jim is correct that it was not the state of the art at the
time and I still wonder why HFO heterodyning was not selected vs fighting
HF Oscillator stability. Maybe Ted addressed this in one of his letters ?
Maybe he was just an L/C man ? Maybe he had some bad design experiences
with crystals ? I know he had strong opinions (and expressed them) about
using a 3500Khz calibration crystal vs the "standard" 100Khz. Plug in
coils are an excellent idea vs bandswitching because of the reduced
complexity, shorter wiring in the critical frontend, less space required,
the possibility for larger coils which improves "Q", etc ....lots of
advantages and only one convenience disadvantage.
