P3/K3
Locked
 
|
G'day,
Anyone using an USB>RS232 interface between the PC an P3/K3 combo. I'm particularly thinking something like the microHAM Digi Keyer. I assume the P3 doesn't need any of the RS232 signals other than TX and RX and can therefore accept the RS232 out of the Digi Keyer which would ordinarily go to the K3 RS232 port. PTT and keying would be taken care of by the Digi Keyer so the RS232 RTS and DTS wouldn't be required. I have a Digi Keyer and it works perfectly well with the K3 and my software; Logger32 and SD (contest) both of which generate perfectly acceptable software CW for me. At present I'm running the the K3 without any external interface into the PC via RS232 and the PC internal sound card. Not quite so easy to play the sound card levels but workable.

Check the archives but I believe this is something you do not want to do.

I don't know about the MicroHam, but a standard adapter should work fine. Some are more RF quiet than others. I have some IO Gear adapters that have proven to be quiet and work without issue with my Debian Linux computer. 73, de Nate N0NB >> -- "The optimist proclaims that we live in the best of all possible worlds.

I run a microHam DigiKeyer II with a P3/K3 combo with no problems at all.

Correct. > PTT and keying would be taken care of by the Digi Keyer so the RS232 RTS > and DTS wouldn't be required. The RTS, CTS and DTR signals are connected directly between the "PC" and "XCVR" RS-232 connectors on the P3. There is no connection to internal circuitry. If the PC software is using these lines for CW keying or other purposes, it should work the same with or without the P3.

Many thanks to all who replied. It is as I suspected but without a P3
schematic I thought it wise to ask. The point about not trying to update P3/K3 firmware through a microHAM interface is understood.
