[Elecraft] Fwd: VHF+UHF Radio Wish List

[G4GNX]

Unfortunately the www.k8gp.net address below does not work for me on this 
side of the pond (UK). Any suggestions?

I came across this “Mother of all switch units”  from Terry K8ZN o
f Directive Systems , and the Grid Pirates. I had read about it in QST and 
filed the idea away for future use…

Then I bought a K3!   and was pondering how to connect all my transverters, 
all from different manufacturers or Home brew..in a way that would take 
advantage of the K3
s great transverter tools!

This was the “missing link” for VHF UHF!

BTW:  The elecraft external band switch is ALSO very capable and will work 
on HF or VHF/UHF, but it requires a bit more hardware, however the HF guys 
have sorted all this out
and a lot of it is applicable to VHF UHF as well, but its not as compact as 
the MOASU.

With a bit of modification Terry’s board talks to the K3 via the RS232 
port - the original design was computer driven via RS232.
This was featured in the World Above in QST in 2008  and here is the link
to the Grid Pirates web… http://www.k8gp.net/station-equipment/moasu or e 
mail Terry. He may have boards and parts left.It is capable of switching
12 bands…but the K3 can only handle 10 if memory serves.

I drive 2x24 V rotary switches from the board, one switches the 28 MHz IF 
from the K3 for 222 and 432, and the other uses the 144 Mhz IF for my 
microwave transverters, plus 144 and 50
as well there are on board relays that move a Demi 4 port sequencer from 
band to band via a set of 3 phono plugs per band, on the back.
Ive also modified it to provide 12 and 24 V switched output for relays and
also integrated a G4FRE / WW2R band decoder board into it just to give me a 
full frequency display… ie 2304.1000 rather than 304.1000 on the K3.

It all works great, I can jump from 50 through 2304 just by switching bands 
on the K3.

I will never part with my K3, unless I go with a k3S that is….
