Re: re ON-OFF on K3

The answer to my problem is to leave the POWER button like it is. I like the way it works. I am not worried about the transient, I like that if the rig is battery powered and the battery goes low the rig turns off and stays off until you turn it back on. I also like the feature that if a connection is too resistive when you transmit the rig will turn off and stay off until you turn it back on. The main "feature" of the K3 that I don't like is that the "HI-FI" enthusiasts have prevailed and it is difficult to copy a CW signal through the background noise without turning off the AGC and using the RF Gain manually. It seems that anything that pleases the HI-FI SWL crowd harms the ability of the K3 to serve the CW and SSB weak signal capabilities. It seems that everything I find to like about the K3 over my TS-850 there is a group lobbying to change.

Re: re ON-OFF on K3

Interesting I'll have to see how much difference this makes by trying it
this way.... I've got things working pretty good by playing with my
slope and threshold settings.

I think that the thing works pretty good for me as a mostly CW op and
I've had quite a few other mostly CW ops feel the same way about it.

The solution is to put the rig(s) on battery power when the mains power fails.

Here in TX we have many power failures in the spring. To prevent losing power
to the rigs at my QTH I automatically switch them the battery power when the
mains fail.Look at the west mountain site:

http://www.westmountainradio.com/RIGrunner.htm for RigRunner information and
then at http://www.westmountainradio.com/order_us48a.htm for information about
PowerGate.
