Exactly my findings at MW2I. Normally we dont use dpb as incoming signals
arrive all over the place frequency wise (in arrl rtty 2010 3 people called
over 1.5khz off!) outside the dpb passband. However it does help with really
weak signals when you have QRM

FT-847 is one example; it has 4 band specific PTT outputs on the back panel,
which are very useful in avoiding keying the 432 amp when on 6m

The K3 reports correctly up to 24999.999MHz. I am currently using mine on
24048.2MHz. Whereas Writelog uses this information appropriately I also have
never managed to get hrd4.1 to display it sensibly

I use the same board/circuit I use to drive VHF transverters from my K3 to
drive my Dunestar. The only difference is the K3 menu settings. I wrote it

Do not be mislead by the manual as I was last weekend during the VHF

The "LP" has nothing to do with low ***RF*** power. It is active when

output that is ONLY active when transverting. To achieve this I had to

As there is virually no lead length between the end of the windings and the
