[Elecraft] [K3] in-band-IMD test

[Mike Harris]

G'day,

I see there is a mod kit $10 but no details available on the "K3 
enhancements and application notes" page on the web site.

The manual would be interesting.

Regards,

Mike VP8NO

| Elecraft have changed the series resistors from 604 to 50 Ohms
| in current production.  See the October schematic updates on
| their web site.

| I'm assuming a change in the schematics indicates the modification
| is now "approved."
