[Elecraft] KPA1500 Low Gain Fault and then distorted output

Does not look very promising. First, I experienced 2 back to back OVR 61 - LOW GAIN freq 10120 inp 7W fwd 40W refl 2W swr 1.5 9A 23C adc169 power ratio 6 and then a single FLT 61 - - LOW GAIN freq 10120 inp 7W fwd 40W refl 2W swr 1.5 9A 23C adc169 power ratio 6 After that no error

Dave, What is the serial number of your K2 - if it is below 3000 and has not been upgraded with the A to B mods, you could have damaged the MCU. 73, Don W3FPR On 5/27/2022 7:58 PM, Dave Sublette wrote: Interesting. Thanks! Dave On Fri, May 27, 2022 at 7:53 PM David Woolley wrote: It's

Re: [Elecraft] Troubleshooting KIO2

It's going to be similar to the application circuit in section 7.1 of , except that not all the wires may be connected, and, in particular, any that conflict with the K2's use of a pin on the connector for Auxbus won't be

Hi Dave Are you sure the PC serial port parameters match the k2? Even with USB, when used with an adapter to 232, the port needs to be set. On Fri, May 27, 2022, 3:48 PM Dave Sublette wrote: > Sorry... I forgot to say that I am using a short adapter cable, DB9-M to > DB-9F that eliminates all

Re: [Elecraft] Troubleshooting KIO2

Dave, DO NOT PLUG THE USB TO SERIAL CABLE DIRECTLY  INTO THE KIO2!!  It will cause 'strange happpenings' and can even damage to the K2. There is a special cable with a DE9 male on one end and a DE9 female on the other end.  The instructions for building it are in the KIO2 manual.  it does

Sorry... I forgot to say that I am using a short adapter cable, DB9-M to DB-9F that eliminates all wire connections except for pins 1,2,3, and 5, per instructions in the K2 Manual. It is new. I just built it and it checks out with an ohmmeter. FYI This K2 has talked to this computer before, but

[Elecraft] Troubleshooting KIO2

Good afternoon, I have a K2 that refuses to talk to my computer. The computer software works and talks to my K3s and an RT21 rotator controller using a straight USB cables. The K2 has a serial port and requires the KUSB cable which plugs into the USB port and terminates in a DB-9 connector. It

Re: [Elecraft] OT: 15 meters last night

At about 0045z on Tuesday morning (your Monday night) I called CQ on 17m CW. For the next hour, I had a solid run of stations in North America. I worked stations in Maine, Florida, VE7, Southern CA, etc. All over the continent, with many 599s. I probably could have continued, but I wanted to
