[Elecraft] Trying to gauge interest

2016-07-12 Thread Ken Arck 

Hello fellow K3 owners!

I still have some boards available if anyone is interested and I'm 
happy to report they work just fine with the KPA3 installed as well!


As my main use for my K3s is 6 meter and 144 EME operation, I bought 
the 10 watt version without the antenna tuner. I dabble a little on 
HF but not a whole lot. As such, the 10 watt, no tuner version suits 
my needs, although I thought it would be nice to be able to select 2 
different antennas from the front panel (one for HF and the other for 
6 meters). Spending several hundred dollars for the KATU seemed a bit 
overkill to me just to get front panel selection of 2 antennas.


So looking at the schematic, I saw how easy it would be to modify my 
KANT board to allow 2 antenna selection. I bread boarded up my 
schematic and It works exactly as I expected.


So I'm debating having some pc boards made to replace the entire KANT 
board but only if there is enough interest to justify doing so and I 
wanted to see how y'all felt about it. The bare boards run $25. You 
would take the parts from your existing KANT and reuse them on this 
new board, in addition to adding around $12 worth of new parts. So 
for under $40, you could have dual antenna selection on your non-KATU 
equipped K3.


Please email me offlist if you're interested

I have wondered often why Elecraft have not done so but maybe antenna swtches 
are common enough they didn't see a need?

If you look at the schematics of the KATU, you'll see the chain of 
shift registers on the KATU actually sends a signal back to the RF 
board. So the CPU sends the command to the KATU and if the ATU 
doesn't respond (via the MISO3 line), the CPU interprets that to mean 
the KATU isn't present


As for handling 100 watts, I don't see a problem as I use the exact 
same OMRON relay the KATU does and I considered inductance in the pc layout

you convince the firmware that an ATU is installed? When I press "ANT" on my

put away, count me in, too. I have always been bummed that I can't get two
antennas without installing the ATU which I do not want to do. I consider an
ATU to be part of the antenna system and should be installed as close to the
antenna as possible (my KAT 500 is at the far end of a 100' coax run).

Looks like you can tell the K3(S) that the ATU is installed and the ANT1/ANT2 
option is enabled:-)


I might be interested too.

[Elecraft] Trying to gauge interest

Hello fellow 10 watt K3 owners!

As my main use for my K3s is 6 meter and 144 EME operation, I bought 
the 10 watt version without the antenna tuner. I dabble a little on 
HF but not a whole lot. As such, the 10 watt, no tuner version suits 
my needs, although I thought it would be nice to be able to select 2 
different antennas from the front panel (one for HF and the other for 
6 meters). Spending several hundred dollars for the KATU seemed a bit 
overkill to me just to get front panel selection of 2 antennas.


So looking at the schematic, I saw how easy it would be to modify my 
KANT board to allow 2 antenna selection. I bread boarded up my 
schematic and It works exactly as I expected.


So I'm debating having some pc boards made to replace the entire KANT 
board but only if there is enough interest to justify doing so and I 
wanted to see how y'all felt about it. I project the bare boards 
would run around $20 to $25. You would take the parts from your 
existing KANT and reuse them on this new board, in addition to adding 
around $12 worth of new parts. So for under $40, you could have dual 
antenna selection on your non-KATU equipped K3.


Any interest?
