[Elecraft] KAT500 LC settings recall -- complete explanation

[Larry Phipps]

I have been reading some of the KAT500 traffic and thought I'd weigh in 
with my particular thoughts.

One reason to have the tuner follow the VFO is that I would like to use 
the KAT500 for receive sometimes for SWL'ing or listening to BCB. In 
this case, I can't transmit, so it would be nice to have the tuner track 
the VFO.

One option is to use the utility to manually select settings, but my 
KAT500 is remoted at the base of my antenna in a waterproof box. A USB 
cable of the required length is not feasible, but I am looking into 
using a wireless USB extender for the task. I already have some wireless 
RS232 serial extenders, but have never tried one for USB. The prices are 
all over the place. Does anyone have any experience with these devices, 
with or without the KAT500? Would they be safe for flashing firmware?

Even with the utility connected, though, there doesn't appear to be any 
easy way to save setups based on names or frequencies. Maybe I've missed 
it since I'm not using the utility.

73,
