KAT500 EEPROM Problem
Locked
 
|
Our club K3 is connected to a KAT500, which is connected to 3 antennas (ANT1: Zero-Five vertical, ANT2: DXCC fan dipole, ANT3: 135ft doublet. Yesterday I was using the K3 on 6 meters with ANT 1 and ANT2, which were not designed for 6 meters. The KAT500 was able to tune for a low SWR, and the TX power was about 50 Watts. No problems occurred during the 6m net, but after the session was over, I noticed that I could no longer select ANT 3 on the KAT500, regardless of the band.
I ran the KAT500 Configuration Software, and verified that ANT 3 is configured for use on all bands but 6m. The configuration SW "Operation" tab could not select ANT3 either (the K3 was turned off). I tried to save the current KAT500 configuration, but a "Save Configuration Error" box popped up after about 10 seconds, which stated "No response to Read EEPROM block". I repeated the process a few times, and the same error occurred each time.The KAT500 firmware is at v1.75. I suspect that RF may have gotten into the KAT500 and corrupted the EEPROM. I'm not sure what to do next. Has anyone encountered a similar problem?

"I ran the KAT500 Configuration Software, and verified that ANT 3 is configured for use on all bands but 6m. The configuration SW "Operation" tab could not select ANT3 either (the K3 was turned off). "
What was the KAT500 mode when you tried this? I have observed, and reported, that antenna selection does not work properly in BYP. Can you change any of the antenna enabled/preferred settings? If so, do they persist through a KAT500 power cycle? No, I have never experienced your EEPROM error and have no suggestions for solving that (except for the suggested test). 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

You mention that you ran the "KAT500 Configuration Software"
but you didn't say that you tried to reload the firmware. Have you tried to RELOAD the firmware? If you didn't reload the firmware, then I would suggest that you give that a try. 73, Ken K3IU ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ On 7/9/2020 12:37 PM, Ed via Elecraft wrote: > Our club K3 is connected to a KAT500, which is connected to 3 antennas (ANT1: Zero-Five vertical, ANT2: DXCC fan dipole, ANT3: 135ft doublet.

No I didn't try to reload the firmware. I was afraid that if the EEPROM was damaged, a firmware update might not be successful, and leave me with an inoperative (bricked) KAT500. According to their web page, Elecraft is not servicing KAT500's due to COVID-19 limited operations. Currently, our KAT500 seems to be working with the other two antennas, so I am waiting to hear from Elecraft regarding the next steps to take.Thanks & 73,EdN2BHD
