[Elecraft] K3 2m Preamps and Amps

[Matthew Cook]

Howdy All,

Can any one tell me the delay between the KEY OUT on the rear panel being
asserted and RF appearing at the output of the K144XV or the ANT
connectors.for that matter?   Is there enough time to switch a mast head
preamp out if harms way?

Also am I right that if CONFIG:KIO3 is set to HF-TRN then DIGOUT0 is
asserted AND the transverter address on the BAND lines (as set by TRN
table) when the 2m band or other transverters are selected?   By anding the
DIGOUT0 and TRN address can I use this to enable an  external amplifer with
suitable PTT interface ???

Are there any other delays here that will put my mast head preamp at risk?

The 10w out of the K144XV has been fun but life is too short for QRP. Need
to make some noise, VK is a big place.
