Alan Wolke: Here's a new video for my ham radio "circle". I built a 40m CW QRP
Transceiver kit from MFJ. I made this video to describe the
schematic/circuit of the unit, and run through a "sweep" of the 65kHz of
tuning range, listening to the CW activity on the lower portion of the 40m
ChrisWilson5006: Another excellent walk through and explanation. Would have been good to see
the alignment. Too late? Thanks Alan!
w2aew: There may be some around. Years ago, there was a series called Warbler, but
I don't know if they're still available.
w2aew: Not a external amp, but I had the AF gain most of the way up.
kd1s: Wow - nice little kit and thank you for the walk through of the circuitry!
CP 1993: ok. thank you. is there one you would suggest for that type of thing that
is still at a low price. under like $300?
Gerry Jurrens: Thanks, Alan! Very cool explanation. I even was able to follow along & I'm
a no-tech Code, you know! Seems like it has a lot of audio output, too, or
was that an external audio amp? 73
Todd Harrison: Thanks! I will be watching this a few times just as a learning tool on how
the glue works in radios. Great Stuff!
Ronald Lijs: Very well explained once more, Alan!! Thanks for this...
w2aew: thanks Joe!
w2aew: You'd be able to receive PSK, but not transmit. There is no tx audio input
(without modifications) for you to be able to do the phase shift keying
May D: Would be nice if you could also do a walk-throught with the Heathkit HW9
w2aew: I'll add that to the list, Don. I don't currently have a clean schematic
for the HW-9, but I should be able to find one.
Brian Boccardi: Gerry has some many toys!
Dennis Hill: You did a great job explaining the circuit. Thanks
Radio wild: Impressive little unit! Really seemed to do well with just a foot and a
half of antenna. Nice job as always! RW
w2aew: If I have time to repeat the alignment before I have to give the unit to
the owner, I'll make a video. No promises!...
N7EWC: Outstanding walkthrough...Great job just made my favorites...Keep producing
great videos...Agree you should have atleast one like from every Ham out
Ed Oxer: Getting set to build one and found your great video. Thanks for the
CT1JRZ: Very nice video. 73
kais avionics: come on guys.... only 60 likes for this outstanding video!!!!!!!!!!
ceMental: Great job as usual.
P T: Excellent video. This was very instructional for me. Thank you
w2aew: Thank you! It's just a lot of reading, studying, building, and
experimenting. You learn a LOT more from mistakes than successes.
CP 1993: this might seem like a silly question but I am vary new to this. my
question is if I could use this with a laptop to do psk with?
wussup331: how do I get to the level you're at? Amazing stuff!
w2aew: Hey Don D - I'm uploading a walk-through of the Heathkit HW9 now!
N4PJA: Fine Business. I haven't found my videos which walk through all the stages
of these radios. Good for me cause there's not many folks around here who
are this knowledgeable or open!
w2aew: Thanks Don. Already done. Found a manual with a schematic that was split up
over three or four pages. I've printed it out and taped it together. I'll
do a video walk through of the schematic sometime soon.
May D: Google on-line HW9 manual and check MW post Thanks
CP 1993: sry I mint to flidgi
