Good Evening,    Another chilly, wet week.  Spring progresses slowly up here. The rain has made it very green.  Moss really does grow on the north sides of trees in Oregon.  It grows on most of the rest of the tree too.  But circular objects only have two sides: in and out.  Propagation

Wes, are you thinking that Elecraft will abandon the KPA/KAT500? No further development? If so, why would they do that? 73 Lyn, W0LEN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Wes Sent: Saturday, May 08, 2021

Re: [Elecraft] KSB2 problems in K2 transceiver

Mark, When you have the problem, look at the voltage at P1 pin 6 (that is VRFDET signal)? If that is high, the MCU will limit power drastically. Make sure Q1 is properly oriented.  If that does not help, try a mod to the KSB2 - reduce R9 to 1.5k and cut the trace between P1 pin 6 and the

Re: [Elecraft] K3 (S) Weird Main RX issue

Does rotating the MAIN RF GAIN knob back and forth make any difference? Or tapping the ANT or RX ANT buttons a lot to exercise the antenna relays? I assume both receivers are listening to ANT1, and nothing is connected to AUX RF or RX ANT. What happens if you move the coax to ANT2? 73, Bob,

Steef, See this recent post for explanation: http://mailman.qth.net/pipermail/elecraft/2021-April/284736.html. The KAT500 can auto-track any Kenwood or Kenwood-compatible rig that outputs frequency data in the format: "FA00014025000;". Connect the RS232 RXD line (Pin 2) of the Kenwood rig to

Re: [Elecraft] KSB2 problems in K2 transceiver

Mark, Pin 5 of U2 provides ALC threshold voltage to the emitter of Q1 on the KSB2 board. The 5.89 V you measured on Pin 5 suggests that the DAC input register B didn't properly load the data word from the MCU. I would check the solder joints on all U2 pins and Pins 14, 16 and 17 of the MCU

[Elecraft] KSB2 problems in K2 transceiver

Today I finished the KSB2 adapter and installed it into my K2. It worked first time but was intermittent. I found the issue as I had omitted to solder the outer top pins of the twin three pin interconnects. That done everything seems ok and then No Apparent RF output. USB/LSB/CW Pressing

AFAICR The KAT500 follows the K3, not the KPA500, as long as the Aux-bus cable is connected. I can certainly hear the relays click on the KAT500 when I tune the K3 across a frequency threshold point. 73, Alan. G4GNX -- Original Message -- From: p...@xs4all.nl To:

Gentleman, I have a problem with the main receiver on one of my K3s. The main receiver is between 6 and 8dB worse than the second receiver. The stupid thing about it: it is not always like that, but the poor sensitivity comes sometimes creeping or sometimes suddenly. It seems to have
