Title: Heathkit HW-101 to AM Post by: CE 3 LQH on May 31, 2005, 02:38:02 PM OK, I have two HW-101's and one works and the other doesnt. Id rather keep the one that does as is. But if I can get the other one working how wexactly would i go about converting it to AM? I was reading some posts earlier but non were specific enough that I got a clear picture? I will use it to drive an old HA-10 AMplifier that is currently being fixed up.
Thanks! es 73's Bryce Salmi KB1LQC Title: Heathkit HW-101 to AM Post by: w3jn on May 31, 2005, 02:47:28 PM Chris, KD2XA outlined the mods here: http://amfone.net/phpBB2/viewtopic.php?t=4723

Title: Re: Heathkit HW-101 to AM Post by: KL7JBB on March 30, 2012, 09:49:41 AM Okay, so it's almost 7 years later. Has anyone else had success with Chris' procedure (linked above)? The interwebs have no other mention of using the HW-101 on AM (well, I suppose because it doesn't seem to make any sense!)
Jim Branch KL7JBB Yeah, this is what I had in mind! Title: Re: Heathkit HW-101 to AM Post by: KA3EKH on March 30, 2012, 11:24:55 AM Isn't that like putting a saddle on a cow? Maybe you can play around with removing the filters or strapping across them but what have you got? Maybe 20 watts of AM when you're done this is assuming you can get AM from the internal junk without using external high level modulation and from what I recall there is no AM receive mode on the 101? But then again I have wasted way more time on projects that make less sense. Come to think of it if I had an old HW lying around that might be a fun project.

I get a 404 error. Chris does a great job with his mod's and I am sure it works quite well. It would be nice to analyze the changes he is suggesting. 73, Joe, GMS Title: Re: Heathkit HW-101 to AM Post by: KC2TAU on March 30, 2012, 12:44:06 PM Here you are! http://www.amwindow.org/tech/htm/hw100plusmods.htm (http://www.amwindow.org/tech/htm/hw100plusmods.htm) Title: Re: Heathkit HW-101 to AM Post by: W2VW on March 31, 2012, 02:20:56 PM Isn't that like putting a saddle on a cow?

Yes, the mod pretty much assumes another receiver will be used and the 101 will only be used as a transmitter. Of course for a hundred bux you can hang a Softrock across the I.F. and it's back in business with FB performance. Probably good for a 20 - 25 watt carrier. Having heard this rig many times I can say it's more effective than a lot of 100 watt class rigs I've heard. That is due to Chris' use of compression. Also works well to drive an AMplifier. Or was that ampliFIRE? Same treatment works for other doorstop slopbucket rigs like the Tempo One. |
