[Elecraft] KX3 band data dongle

[Larry Hagood]

I would like to use a small (40 watt) amp with my KX3 when the 10 watts just won't cut it.  There's a neat looking little Chinese amp on ebay for about $300 (MX-P50A) it interfaces directly with the FT-817 for auto bandswitching. How hard would it be to construct a dongle that plugs into the KX3 acc jack but then emulates an 817 acc jack (band data out only) Thanks!-Larry
