Guys - thanks for the replies! By now you've probably read my post that I got it all working. As to having the SLUSB, after reading the K3 and KE7X manuals, it just seems that using the external sound card like the SLUSB makes it a little easier. Haven't looked at the iMic, but with the SLUSB,

Mike, That has been true up to this year. But I believe that the latest iMac has gone over to the single plug system just like the Macbook Air. 73, Oliver W6ODJ On 12 Jan. 2012, at 06:25 AM, Mike Reublin n...@nf4l.com wrote: An iMic will give you separate in/out audio jacks. 73, Mike

Jim, Just make sure when adjusting the power your ALC reading on the K3 must show 4 bars of ALC with the 5th bar just flashing. This is counter intuitive based on other rigs but a necessity for the K3. If you are using the line in gain or the TX control on the SLUSB to regulate power you may be

Seems like there is some confusion between iMics and iMacs on this thread :-) At any rate since you are already using the SL no need for an iMic at this time. BTW, lately my configuration for RTTY and PSK 31 has been to use Rumlog. It uses the internal FSK function of the K3 and when

Looks like I misspoke when I said I could leave the K3's PWR set at 90 and adjust the RF output via the SLUSB. Doesn't quite work that way! RF power out stays up in the stratosphere (PSK31 speaking, anyway) so I really do have to set the K3 to about 25-30 watts out on the K3 and adjust the ALC

Jim, Due to the way the K3 controls power, you must ignore the many instances in Data software instructions and other sites on the web which tell you to set the power for maximum and use the audio level to control the power. That just will not work for the K3 (or the K2 for that matter). You

The other issue with the SLUSB audio level setting is that if you use a program like DM780 to watch PSK (several conversations at once) then click on one to use, the actual tones used will change. The audio drive at 1KHz will be different than if you select 1.8KHz so the ALC response may (likely

Jim, Not sure why you feel the need for the SL with your K3 but that's up to you. Anyway, no need for a dummy load with the K3. Basically put the K3 in Test mode set the pwr to 30 or 40 or whatever you like, adjust the pots on the SL to show 4 bars of ALC with the 5th bar flickering, take the
