KPA500 Port problem
Locked
 
|
I live in a nursing home and am mobility impaired and must control my KPA500
with my computer. I saved for over a year for the amp. My KPA500 will stay connect to my computer for <2 min and the Utility locks up and the only way to get it to load again is to re-boot the computer. The error messages I receive all say the port is in use which it is not. I have uninstalled and re-install the FTID comport driver many times. The baud rate of 38400 for both computer and amp. I have downgraded and up graded the firmware.

Tim,
Why don’t you try using the KPA500 remote software instead? Here is the link: https://elecraft.com/pages/kpa1500-kpa500-kat500-remote-software <https://elecraft.com/pages/kpa1500-kpa500-kat500-remote-software> Raj, N2RD > On Mar 3, 2021, at 11:45 AM, Tim C <[hidden email]> wrote: > > I live in a nursing home and am mobility impaired and must control my KPA500 with my computer.

When does it disconnect?
Does it disconnect if you don't transmit? Does it disconnect if you transmit with the KPA500 in standby? Does it disconnect if you transmit with the KPA500 operating? Does it matter which band you are on? If the answers to the above are different, you may have an RF on the USB / RS232 problem that is present during high power transmissions. Try bonding the computer to the amp with a wide braid and make sure both are grounded well. If you are on an upper floor, maybe a counterpoise might be needed. The KPA500 remote utility works well, but needs two computers, one near the KPA500 and one near the shack. The advantage is you don't have to use long USB / RS232 cables. The two computers can be on WiFi which usually is not bothered by HF. 73, Mark W7MLG On Wed, Mar 3, 2021 at 9:46 AM Tim C <[hidden email]> wrote: > > I live in a nursing home and am mobility impaired and must control my KPA500 with my computer.
