Hi Wayne and all, I have just installed the latest production firmware (4.30) and my 2M S meter readings have reverted back to the old (pre beta 4.29) behaviour. (ie: the S meter reads S 4 for a S 9 repeater signal.) Can anyone else confirm this? TIA

The K3EXREF module uses the external 10-MHz reference to determine the exact frequency of the 49-MHz internal reference. If a K144XV PLL is also installed, we know that the 2-meter module is phase-locked to it. We then apply an offset to the 10-meter IF mathematically so that the 2-meter frequency is dead on. This calculated offset replaces the manually entered offsets in the XVn OFS menu entry. 73, Wayne N6KR ---- http://www.elecraft.com On Mar 22, 2011, at 6:08 AM, Jan Holmer SM6TUW <[email protected]> wrote: > Wayne, > > The 116/118 MHz PLL can obviously not be locked to the 49 MHz ref as you > mentioned in an early posting > describing the functions of the coming K144XV add-on board. > The present FLL solution of the KREF3 corrects the 49 MHz internally. > Which external ref will be used for the K144XV PLL, the ext ref (10 MHz)? > > Jan > SM6TUW > > > wayne burdick wrote: >> >> Jan Holmer SM6TUW wrote: >> >> > Wayne, David, my question was unclear: I was referring to the >> > optional PCB to >> > be installed inside the K144XV on top of the tranverter PCB. >> > The K144XV I already have.
