[HBR] HBR-8 Questions

[Glenn Finerman]

Howdy folks;

This is my first post to the HBR list. I've been a ham for 30 years now and
I'm finally getting around to homebrewing some receivers. I'd like to start
with the simple HBR-8 but was wondering if it would be possible to just add
an AM detector without the other changes via the HBR-11. I'd like to also
use the receiver to listen to AM SW broadcasts in the 40 mtr band. Please
forgive this next stupid question but I noticed there is a BFO switch on the
HBR-8 yet the article mentions "treating the AM signal exactly as though it
were SSB".

I guess what I'm asking is, why is there a BFO switch if carrier injection
is always required to receive CW and SSB with the product detector? Doesn't
turning off the BFO disable you from receiving SSB and CW? I would think
just shutting off the BFO would allow you to receive AM. (with a diode
detector?)


Thanks for the help gang! I'm looking forward to some building fun in the
future!
