[Elecraft] Dunstar Question - ANSWERED - Thanks

[Joe Subich, W4TV]

Dick,

The Y connector directly parallels the BCD lines of the KPA-500 and
whatever device is connected to the other leg of the Y.  In some
cases, one device can load the lines such that the other device does
not decode reliably.  Check your Dunestar (and any decoder used to
control the Dunestar - from memory the Dunestar 600 is "one line per
band" and not BCD) for proper operation when connected in parallel
with the KPA-500.

73,

    ... Joe, W4TV
