Need information on HB KWM-1 (update)

[James True N5ARW]

Thanks to all those who responded to my question so far: Dr. Johnson, Kees Talen, Lorne Barber & Gary Harmon.

Here is what I have learned so far.  The rig was built from an article in GE Ham News "The LWM-3—Mobile SSB Transceiver".  Part I appeared in the Nov-Dec 1961 (#16-6) and part II in Jan-Feb 1962 (#17-1).  Gary is sending me photocopies of these articles.  It uses a 12BY7 for the final so it is kind of a QRP rig.  There was a later article (issue unknown) that described an external amplifier to boost the power.  

I would still like to get originals of these issues if anyone has duplicates.  Actually, I need most issues from 1961 (16-1) and later,  and I have duplicates of earlier issues to trade.  I will post the articles on the web site for those who are interested.

I would also like to hear from anyone who built or used one of these rigs.  If you want to send photos and or stories or links to your web site, I will add them to the LWM-3 page.

Thanks to everyone & 73

Someone saw it and told me they thought it was a KWM-1 clone built from an article in GE Ham News but I can't find it in any of the copies I have.  No luck in RCA Ham Tips either.  It does have a Collins mechanical filter.  If anyone has any information on this rig, I would really like to know more.  Please take a look at the photos and see if you recognize it.
