[1000mp] ft1000mp mkV amp switching

[on4vp]

Dirk,

I connected my acom 1000 in both ways :

using the band data connector for QSK operation and using the TX gnd with
switch set to the 'on' position, both worked fine.

Of what I've been reading, the band data connection should improve the key
time ...
I use it now for the moment with the switch set in the 'off' position.

73, Phil, ON4VP

rear panel is connected to an internal relay, for non-QSK T/R swithcing of
lineair amplifiers that use AC switching voltage or DC voltage greater than
+15V, negative DC voltage of any kind (such as the HEATH SB220/SB221 models)
or if they are required to sink more than 100mA for T/R switching.  A

manual states that this relay is capable of switching 125V@500mA or
220V@300mA  AC or DC . (found in the technical overview on VA3CR  website)

with the mkV ?
