> Quite some time back - like about 12 years - on a boring February day that to my memory was my birthday and I was killing time waiting for the in-laws to arrive for dinner.... I hooked up my K2 to a Technical Materiels Corporation milspec linear amp... PAL 350. This amp is meant to be paired with a low output TMC exciter (around 1 watt) and is conservatively rated at 350 watts output.
>
> I think I used a Dow Key relay for T/R, dialled down the K2 to a low power level with an attenuator in line for good measure, and about 6 arms and hands to do all the manual switching of the Dow Key relay 110 volt wall switch device and turning the amp to Operate etc. The amp has an amazing number of fail-safe triggers (I guess for fumble fingering operators and newbie GIs, HI) so anything weird or more power than it liked...it just tripped off the safety.
>
> It was a resounding amount of weird fun and I worked Hawaii on 'fone for I think my first and last time... on 20m.
>
> Not for the faint hearted or something I would normally do in the regular operation of the shack. But I had time to burn. And definitely not QSK operation.
>
> This would of course be easier with a rig like the K3 with an  key-line output. Heck, even my tube based Johnson Ranger has a key line output in its T/R and receiver mute box. I still think I need a Private to run the TMC amp's knobs, bobs and whistles though.....
> Mind you, you should have seen the TMC  kilowatt amp that partially devoured my basement for a while... almost as big as a PDP-11 computer frame. Long gone, heavy beast. Did fit into a Volvo station wagon though.

>
> A: If the whip is close to resonance, which will usually be the case on 20 meters, coax losses should be fairly small even with longer runs, say up to 15 feet. When using the AX1 on 17 and 15 meters where an ATU is required, use 3 feet or less to avoid significant feed point loss. A tripod can be set up very close to the operating position at low power levels, so this requirement can be easily met.

> A: Yes. But that the AX1 is primarily intended for pedestrian mobile, rapid deployment, and as a backup to full size antennas. A longer/higher antenna should be used if supports are available and time permits. I always bring wire to toss into a tree, but my emphasis is on quickly moving from one spot to the next -- literally walking while operating at times -- making the AX1 indispensable.

> A: If stations are looking for you, as in SOTA operation, sure. But generally at QRP levels with any kind of portable antenna it's more productive to call other stations, with emphasis on trying strong stations first. Strong stations are usually correlated with good propagation, and/or great antennas at their end, which benefits both ends of the QSO.
