addendum to K2 problem

Hi again

Well this morning I checked all the coax connections all snug soldered connections to g5rv window line intact
Re checked the K2/100 and KAT100
Here’s the results

no lights on SWR below 20M again variable output and SWR

SO…it turns out I have a faulty cable from the shack to the outside box. I switched to a diff line and all is well for now

Thanks for all the support over the years
Sorry for the false alarm.

Re: addendum to K2 problem

Having heard stories like this hundreds of times over the years, why do we
start by thinking the radio is broken? :>)) Wish I had a buck for every
post here complaining about radio gear that wound up completely external to
K2, K3, KATxxx, etc. In some cases it was a really hard sell to get the guy
to go outside to find where the problem really was.

Is that because the radio is in front of us and has lights on, and
therefore is what our eyes fasten upon? Or are we really that
pre-disaffected with our radios?

Probably neither. It seems to be basic human nature to assume the
worst. Kid is overdue from a school event, "OMG, Kevin's been kidnapped!"

In reply to this post by Guy Olinger K2AV

I estimate that something over 90% of all the problems I have had with rigs
over the years not performing up to spec came from from bad coax and
connector installation. That's the first thing I suspect now. Goofy tune
up, weird SWR readings, lo-no output, poor signal reception, hair loss and
gout, all from bad connectors and bad coax!

It's not always that, of course, but it has been the first place to start
looking, and testing every part of the feed line from S0-239 to driven
element!

Re: addendum to K2 problem

That is why I first ask how the transceiver behaves when connected to a
dummy load.
Even that is not conclusive because there is always the possibility of a
faulty coax between the transceiver and the dummy load, but it does
usually rule out a fault in the transceiver and force attention to the
antenna system.

Bad connections in the antenna system can cause all kinds of 'strange
happenings'.
