I do indeed have the "over modulation" modification, however I believe
that is one of those published in ER.
The one that I *DO* have, that most likely is NOT out and published, is
not very well documented. However, Bill gave me a complete "FINAL
Heath" manual, with the schematic containing the PTT mod. The audio mod
is there, and I do not remember off-hand if the 160mtr mod is.
The only thing I have in a transmittable form would be the "last"
schematic. I certainly haven't scanned the remainder - which included
the ER articles.
I have NO idea what size files that you can handle. I have broadband
connectivity, so zI can either send the schematic in its three pieces,
OR I can load them on my website for download, giving you the direct
links for the three pieces. BE ADVISED! Each is approx 3MB in size!
I believe that you are quite able to read them and figure them out!
(I type by the Columbus Method - seek out, land upon - and discover)
All typos are inadvertent and due to going too fast!
