Anyone having this problem? This is everything I can think of:
When running digital, my computer looses contact with my K3/P3/KPA500/KAT500. In other words, DM780 stops working necessitating shutting down HRD, pulling and re-plugging in the USB connection, restarting HRD. Sometime the K3 is locked in transmit and needs to be shut down too because I have no response from any of the buttons. It doesn't seem to matter what power output I run. I will sometimes get an error message about serial stopped working. I am thinking this is an RF problem, but have not been able to locate and solve it. I have wrapped multiple turns of the USB/serial cable on a mix 31 toroid, rechecked my house and antenna ground system. The antenna I am using is a remote tuned vertical about 90 feet away with 35 ground radials. Computer is a laptop (I have several with XP, W7 and W8) doesn't make any difference which one I use. The KAT500 has 2 antennas connected, the vertical and an OCF dipole (rarely used). The tuner is only used when using the dipole. Is it possible there is not enough isolation between the antennas? All coax is RG8, except in the shack 8U for the interconnects between K3 and KPA500. This problem doesn't happen when using FLdigi. But then I need to log manually or am using N1MM in contests. Shack is on the 2nd floor, grounded through the copper radiator system, and jumpered to 2 separate ground rods in basement. All equipment is connected to one common ground using 1 1/2" braid. All rig interconnects are Elecraft. No 3rd party. HRD is latest version. I been scratching my head over this for several months. -- John Fritze Jr K2QY k...@arrl.net ACACES president 2014 Albany County RACES Radio Officer ARES ENY DEC Northern District Hudson Div. Asst.
