PK-232 and TS-680 (aux port)

1. The PK-232 will cause ssb and fm distortion when plugged in to a TS-680 (aux port). My fix has been to add a 470 pF. Hi-Q disk cap. in series with the TX-audio line, and leave the mic gain at maximum. I also have the 600 ohm divider resistor (R 151 radio 1) lifted but don't know if it still helps after the cap mod.

2. When switching from Com-Fax to Com-Pakratt cartridges the RTTY Rx-after-Tx key F7 is disabled. The fix is to enter Terminal mode on Com-Pakratt (<C=> t) and then enter conmode converse.
