Tom,
If you have not yet made the K3 switch to the 1 amp output, that alone
could explain the problem, especially if you have the SVGA option in

Thanks Don.
I measured the power supply sag at the power supply to be about 0.05

The supplied amplifier, control board, enclosure, etc. make a nearly

If I had 400 feet for an antenna that's the type of antenna that I would
go for too, but I barely have 400 inches. Have fun with

With the discontinuation of the K3S, I decided to take a look at the website to
see if the KSYN3A updated synthesizer modules are still available for my
original K3, s/n 559. It does not appear there anymore. Are these updated synth
modules in fact, now gone?

Hi All,
Will the K4 support a keyboard and mouse being connected using only one of its
USB ports
as would occur with a KVM switch?

Thanks for your info which together with Don's has helped clarify my thinking

The mist is at last clearing. I have the CBLP3Y connected as per the P3 manual
