Hi JJ,
the note on the 1T DBM was reported in RadCom, Technical Topics column,
June 2004.
I asked a friend to insert all mixer infos in my web page
www.qsl.net/i7swx but I do not know when he will be able to do it. In
my web page in homebrewing you my read the experiences and measuremnts
done by JA9TTT on both versions (3T & 2T) of the H-Mode Mixer. This is
a software package translation from japanese but it is understandable.
You will be able to see Spectrum Analyzer measurents too.
If you send me (callsignatyahoo.com) your e-mail address I can send you
the complete 1T DBM note in english (more stuff than in TT).
A NOTE for ALLISON ... I see you have been fiddling with DEC stuff.
Were you working for DEC or a customer? I was with DEC for a quarter of
a century ...hi
