Thanks Arv,
I've had the AFU callsign for about ten years and you're the first
person to comment on it. I thought it was funny when it was first
assigned to me but nobody seemed to share my sense of humor. Thanks
for noticing!
Thanks for the huff&puff invite. I've also been looknig at Hans
Summers website and I'm thinking about trying it out. My current CW
rcvr is the popcorn rcvr from the qrp homebuilder homepage. It has
an LO freq of approx 2.5 MHz (4.433 MHz IF)and is pretty stable ( I
think I remember about 2Hz per minute after warm-up but it's been a
while since I measured it so I could be wrong) but I am intrigued by
the H&P. Lately I have been finishing up a presettable frequency
counter that I can run directly off of my VFO. Now I know where I am
on the band. It can be found at:
It's at the bottom of the homepage.
Thanks for the invite and I will start checking out the H&P group.
73's & HPE CUL.

The BITX has also been used for CW. Several builders have added
a
center-of-the-filter
BFO oscillator that serves both send and receive CW functions. I
took the
simple way and
just added a keyed AF oscillator that plugs into the mike jack.
Love the callsign. I'll bet you get a few comments about it
though!
I did not see your name in the members list for the Huff and Puff
group so
I will go
over there and send you an invite. The Huff & Puff VFO group
forum is a
logical
extension to the BITX because using an H & P circuit to stabilize
your
BITX oscillator
makes it into a very stable but still inexpensive rig that is
capable of
working with
narrow filters for CW and PSK/MSK contacts.
