Hello Ron,
Yes I am.
I raised this issue several month ago during the announcement of the K3.
I did suggest the Ten-Tec solution which works fantastic.
Before RF gets out (either from the main antenna or transverter RF-out), the
TX-Request initiated by the PTT/VOX/Key from the K3 (which should be

Hi Evert,
prevent the exiter to give RF if one piece of the added hardware isn't
working properly.
This, I suppose, would be fairly easy to do with an external piece of
hardware, assuming that the various devices/switches offer you some kind
of feed back, and you route your keyer, foot
Fellas:
Not being a VHF guy, please help me understand the need for a sequencer...
The K3 already issues a T-R relay output closure some tome before RF is
generated at it's output. This allows external devices 'down stream' of
the K3 itself to actuate their T-R relays so they will be in-line by
Hi Ron,
you are not alone - be sure!
This (sequencing) is also (IMHO) related to SemiBK/QSK mode in CW
without possibility to use only PTT. I hope this is already on some
wish-list.
And TX INHIBIT method mentioned by Evert is also very good idea.
I know that group of VHF/UHF/SHF operators
Tom,
That is exactly the point - 20 ms is often not enough time to change
antennas and protect the preamps located on the tower. My CW PTT
addition to the K2 does provide a 'TX-enable' function and has found

Hi Tom (and others),
I think Don answered almost complete to your question but
I'd like to elaborate a little on this subject which is unnecessary for and
even unknown by most HF operators.
For serious VHF/UHF operation, it is important to have a system with low
noise figure (typical between

Hi Ronnie,
I agree with your idea of a sequencer inside the K3.
Both the K2 and the K3 have delayed keying, but it is not long enough
for multiple external devices to settle down.
It may happen in time as Eric and Wayne catch up on the wish list
that is getting
