Re: [Elecraft] KAT500 failure

"It's still working over 30 minutes after the fridge cold soak." I was tricked by confirmation bias. The cold soak was not what fixed the problem. My controller sent a valid command that the KAT500 firmware took exception to. I'll withhold the details but other KAT500 users will not

"I guess that the 10uF electric capacitor connected to LM7805 output is a possible cause." All the front panel LED seem to be on that same 5V rail and they stay normal brightness in the fault condition. I suspect something, other than low voltage is killing the MCU. It's still working over

"I'm suspecting the KAT500 has a thermal problem. Does anyone recognize these symptoms and know a probable cause?" I put it in the fridge for 30 minutes and now it powers up normally, connects to KAT Utility and responds to utility commands. It's clear it's a thermal problem but which

[Elecraft] KAT500 failure

My KAT500 has stopped communicating with my controller and does not power up normally. With PC data cable removed, when I pull and replace the power plug the KAT500 powers up with a relay clunk and with MAN and ANT 1 LED lit. All front panel buttons are unresponsive. The same thing happened a

Re: [Elecraft] KAT500 Question - Manual Mode Light is Flashing

Andy, I kept the KAT500 in auto tune mode & I think I solved the problem...1) a loose plug in the back of the KAT500 & 2) probably snow or frozen participation on the antenna connection. Not sure what finally solved it, but all seems to be well During the contest so far. Tnx , Irwin KD3TB On

[Elecraft] KAT500 Question - Manual Mode Light is Flashing

"When I have the Tuner in By-Pass Mode for an antenna with a low SWR, even when making small changes in the frequency, the Tune switches to MAN (Manual Mode) and the MAN light is flashing. How do I get it to stay in By-Pass Mode." One reason for flashing MAN is that KAT500 has entered auto tune

Re: [Elecraft] KAT500

Glad you got this figured out. I was hit the same way on a WTB ad. Fortunately, the payment instructions in the offer to sell just didn’t smell quite right. And sure enough, I contacted the supposed seller, and he didn’t know what I was talking about. It’s a “buyer beware” world out there

Hello Again, Sorry for being so “mysterious” yesterday. Several of you have written, some with helpful suggestions, but many being curious about what I thought was “suspicious” about the KAT500 transaction. Briefly, I have learned when you place a “WTB:” ad on QTH.com, you often encounter

Hello, I have a guy trying to sell me a used KAT500, SN 0296. He sent me an actual photo with the SN clearly showing. Also in the photo is KPA500 SN 0702. Something seems suspicious. I did a Google image search, but the results were inconclusive. Does anyone in this group own, or has ever owned

Re: [Elecraft] KAT500

Sure. Just select bypass for the antenna on the front panel. When you QSY to that band, the setting will take affect and the ATU will be in bypass mode. I do this with my tribander, which does not need the ATU, just the switch. 73! Jack, W6FB > On Jan 17, 2021, at 12:53 PM, Jack W4GRJ wrote:

Re: [Elecraft] KAT500 lost serial comms - try factory defaults?

Hi all, A follow-up on my problem: today I’ve opened up the belly of the KAT500 and have done some testing. With no USB cable connected and the KAT500 powered up, the Q1 drain voltage is 2.39V, where I would expect 5V. Also the gate voltage is 2.30V, where I would expect it to be floating.

Re: [Elecraft] KAT500 lost serial comms - try factory defaults?

Frank, I would start with a complete power removal (not just off) to the KAT500 and the computer (unplugged from power).  Then go have a cuppa.  When you get back, plug the power in and restart it and test. I have found that some devices (more in the USB realm) occasionally 'stick' when

[Elecraft] KAT500 lost serial comms - try factory defaults?

Hi all, I’ve used my KAT500 with pleasure for many years, but recently a problem has arisen: I’ve lost the serial communication feature. I’ve already swapped the KXUSB cable with another one (home-brew) so I’m pretty sure it’s not the KXUSB that’s gone kaput. And the PC is doing USB comms fine
