The PRE icon pertains only to the K3's internal preamp. I suggest turning it off in most cases when you're using the PR6. Otherwise you'll have more gain than necessary, possibly degrading dynamic range. (With the PR6 on -- giving you an MDS of about -144 dBm -- turning on the internal preamp would provide only a small fraction of a dB improvement.)
To turn the PR6 itself on, you need to turn on the RX ANT path (which you have done), but you also have to power the preamp. You can leave it powered all the time (via a jumper block, if I'm remembering correctly), or (preferably) turn it on/off using the DIGOUT1 signal on the 15-pin accessory jack. The PR6 manual should cover all of this. 73, Wayne N6KR On Dec 4, 2009, at 10:32 AM, Mike wrote: > No one knows? > > Mike wrote: >> I installed the PR6, hooked up to the control line.
