The list "din" over relocating the VFO LINK function off of the SUB RX button seems to have subsided... The following comments are about LINK, and not about the fabulous DIVERSITY function:
I am VERY pleased that Elecraft has relocated the VFO LINK function off of the SUB button. Accidental LINK of VFO A/B during at least three major DXpeditions has been a serious problem, which has probably cost numerous DXpedition QSOs. During the heat of DXpedition operations, it is very easy for even a well-seasoned K3 operator to get the critical hold timing on the SUB button wrong enough to enable LINK. Then as the DXpedition operator tunes his SPLIT QSX frequency looking for callers, his own TX frequency moves up and down the band in step per the command of VFO LINK. The pileup becomes totally confused, the QSO rate goes to ZERO, and the DXpedition op does not realize what is happening. Most DXpedition ops are looking at their QSX pileup frequency, not at their TX frequency, and the little blinking decimal point is unnoticed. I have mulled over this K3 LINK function for quite some time. In my 43 years of ham radio operating, I can only think of one situation where I wanted to LINK my TX and RX VFOs: Early AMSAT OSCAR satellites with linear cross-band transponders. But, for those who can find a need for LINK, I am glad that Elecraft has retained that functionality - just not on the SUB button 73, Terry K4RX +++++ Subject: Re: [Elecraft] [Elecraft_K3] Who said anything about removing diversity? That would *never* happen... In diversity mode, the main and sub RX synthesizers are guaranteed to be phase-locked to each other if the crystal filters selected for main and sub both have exactly the same frequency offset. The offset for all 8-pole filters is 0.00. The offset for 5-pole filters varies, and can be ordered in matched sets for main/sub.
