[CW] Fw: CW Re-generation: Magazine article list

[Henry Mei'l's]

Here are some the articles i have in photocopy form - dont' hav scanner now, but hope to have access to one soon.
I also have my own original design diagrams & working units

Electronics World, Mar. 1962:  pp 52-5, 70      'QRM Eliminator'- pp 52-4, 70, 132-3  (2x12AT7)  Wien bridge osc. & Schmitt trigger
CQ,                      Oct. 1968:  pp 34-5, 132-3  ''The Signal Souper' -12AT7/12AX7 
HR,                      Jun. 1970:  pp 24-27           'Integrated audio filter-frequency for cw recpetion' -wave shaper & gating IC ckts
HR,                      Apr   1974: pp 54-7             'CW regenerator for interference-free comuniations. -uses a PLL

I believe there are one or more US (& psbly UK) patents along these lines - these can be downloaded from the Patent Office internet sites.

Let us all know if any of you build one or more and what you expereince with them. I will reactivate and modernize my own two HB units from the early 1960's.

I found my CW-topic looseleaf (right on the shelf, just where it should be) -- it includes several magazine construction articles. I will send a list of them this weekend.
