Hi all, I love my K2, and need to use it for ecomm work if ever there is an emgergency down here. It is a good excuse to bring it to the EOC, so it doesn't dissappear when the island I live on dissappears in the next Katrina. I have finally gotten on HF Pactor I with my K2. This endeavor has taken me a year to accomplish. I have my notes below if anyone else is interested. It ends up being just like any other digital mode but the setup is a little more complicated. Pactor I on PK-232/mbx/vers.7.1 for Electraft K2:
1) Com2 is Gold-x USB to serial converter on rear bottom USB slot. This goes to the K2 for CAT support in Airmail. In the PC, the parameters should be: 8,N,2, 4800 (control panel, XP). 2) In Airmail the parameters to communicate with K2 are: 8 data bits, parity none, 2 stop bits, baud rate is 4800. 3) Com1 is the Sakar International Iconcepts USB to serial converter rear top USB slot. This goes to the PK-232. In the PC (control panel for XP), the parameters should be 8,N,1,9600 (this is against the recommendation in the PK-232 manual, which states 7,E,1). 4) The PK-232 JP-1 pin should be removed so the unit will auto baud on startup. It is next to the battery. On this model (ser. 20987) the cover must be removed to access it. 5) In Airmail set the Modem to PK-232, Port to Com1, and baud rate to 9600. For radio connection choose “direct via Com port”, “Com2”, and baud equal to 4800, and radio type equal Kenwood. Also check “lock” radio. For audio tone check “LSB”. The center frequency defaults to 2210, which can not be changed for the PK-232. 6) Set the K2 to 50 Watts (with external fan), put the meter in ALC mode, and set the mode to RTTY. This mode is LSB but there is no speech compression. The K2 IF filters for RTTY mode have been set up for Pactor I. The filters are centered about 2210 Hz, which is what the PK-232 sends. FL2 has been tested and works well (about 1290 Hz). 7) The afsk setting at the rear of the PK-232 case should be set just high enough to achieve proper output when connected to a dummy load. No more than two bars should show on the ALC. This setting should only need to be done once. 8) To operate set AGC to fast, (AirMail should do this for you but check). 9) Airmail will default to LSB, so manually select RTTY mode, and then select the second filter “FL2”. Airmail will tune the K2 to the exact frequency. Regards, Steve, W2MY Corpus Christi -- No virus found in this outgoing message. Checked by AVG Free Edition.
