[Elecraft] Ameritron ARI-500 and K3?

[Phil & Debbie Salas]

I use the ARI-500 with my ALS-600.  Should be the same hookup.  The K3 band 
data output is identical to the Yaesu band data output.  The ARI-500 
interprets it just fine.  If you have an early K3 you do need the TTL 
pull-up mod.  My ARI-500 manual has the wiring information.  Email me at 
ad5x at arrl.net and I can email you the manual if you have an older version of 
the manual without this info.
