Re: [Elecraft] Any progress on K3 modules?

Hi Pete, I just rechecked status on these boards. It looks like the KSYN3 will be the first one to be manufactured. I'm not sure about the KIO3. Unfortunately all of these modules (like everything from toasters to Teslas) are subject to supply chain issues, and in most cases just one or two

[Elecraft] Any progress on K3 modules?

Has there been any progress on the planned final production run of the KIO3 Upgrade Kit?  I ordered one just before everything stopped in 2020, and put my name on the "last chance" list in 2021, but have heard nothing since. -- 73, Pete N4ZR Check out the new Reverse Beacon Network web server

7.5V It is not there to regulate, but to limit in case of something bad happening, while allowing the gate of the FET to get the full control voltage for T/R switching. The zener normally is not conducting. 73, Lyle KK7P On Wed, Aug 17, 2022 at 12:08 PM RALPH TURK wrote: > The real question

Re: [Elecraft] K4 remote software progress

Hi Wayne, I appreciate that update. The latest I heard is maybe 18 months old or so, so already this is significant update for me. Updates will be appreciated as they come. Just seeing progress on the items needed to be complete is encouragement and progress, even if it does not give a date

The real question is/was what value of zener. > On 08/17/2022 9:45 AM Andy Durbin wrote: > > > "The latest revision of the schematic for the KPA500 TR Switch shows a Zener > diode at the gate of Q4 in place of R3, the 100K resistor previously." > > What is the latest revision? I have Rev D

"The latest revision of the schematic for the KPA500 TR Switch shows a Zener diode at the gate of Q4 in place of R3, the 100K resistor previously." What is the latest revision? I have Rev D which is later than any I have found on-line but it shows R3 not a Zener. Andy, k3wyc

[Elecraft] K3 serial port

Thanks to everyone who offered educated thoughts on my problem.  I just discovered that the problem apparently lay in my USB hub, perhaps as simple as a loose connector.  I plugged the USB cable into a computer port directly and voila!  So I now have frequency control communications again. 

Re: [Elecraft] Diagnosing Serial Port Issue

Hi Pete, First of all, the „active“ part of the USB cable is the USB-to-serial converter. This communicates with your computer even if the cable is not plugged into your transceiver. So to find the root cause, I would not plug in the transceiver end of the cable at all for the following: 1.
