berkmanyt: Nice job…. AGAIN….Thank you walt K2CXP
Michael Lloyd: This was awesome. I just built the exact MFJ transceiver and the walkthru was very helpful. The only complaint I have is that it's going to take me a long time to get through your site :) I haven't aligned mine yet. It seems pretty easy but it would have been nice to watch you go through it
w2aew: It would involve more than just changing the toroid windings and changing the crystal. You'd have to adjust the receive bandpass filter, the VFO used for the rx and tx LO, the transmit bandpass filter, and the tx PA output filter. That's assuming that the buffers and PA are up to the task for 28MHz operation, which might not be the case...
WX9DX: Can you get it to work on 10 meters with some re winding and a different crystal?
w2aew: There may be some around. Years ago, there was a series called Warbler, but I don't know if they're still available.
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?
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 modulation.
CP 1993: sry I mint to flidgi
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?
w2aew: Thank you! It's just a lot of reading, studying, building, and experimenting. You learn a LOT more from mistakes than successes.
wussup331: how do I get to the level you're at? Amazing stuff!
Ed Oxer: Getting set to build one and found your great video. Thanks for the informative talk.
N7EWC: Outstanding walkthrough...Great job just made my favorites...Keep producing great videos...Agree you should have atleast one like from every Ham out there...
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!
P T: Excellent video. This was very instructional for me. Thank you
CT1JRZ: Very nice video.
w2aew: Hey Don D - I'm uploading a walk-through of the Heathkit HW9 now!
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
