When the KPA100 is not installed, my K2/QRP operates normally.
However, with KPA100 installed I have no incremental power control and
no lit LEDs on the K2 S/RF meter.
The SWR is indicated to be 1:1 into an OHR RFL 100 Dummy Load. "HiCur"
does flash on momentarily after switching to the 80 & 40 meter bands.
I am using my straight key to key the K2... not TUNE.
First test on 40Mtr band:
Both Hi Current and Lo Current Power Supplies on:
Requested power = .1 to 10w, power to dummy load = 20w
Requested power = 11 to 110w, power to load = 110w
With only Lo Current Power Supply on:
Requested power = .1 to 15w, power to load = 10w
I cycled DC power off/on:
Requested power = .1, power to load = .3w
Requested power = 10, power to load = 10
I backed off requested power:
Requested power = .1, power to load = 10w
I turned Hi Current Power Supply on:
And raised requested power:
Requested power = 20w, power to load = 110w
Then backed off again:
Requested power = 9.5w, power to load = 10w
Band Initial Power readings after I
raised
(Mtr) Power requested pwr past about 1w.
(With Hi and Lo Current Power Supplies on:)
160-15 0 20, 110
12, 10 0 3, 25
(With only the Lo Current Power Supply on:)
160-15 0 10, 10
12, 10 0 3, 3
(The lower power readings read when =< 10W requested, the higher power
readings read when > 10W requested and the Initial Power is what I
read just after switching bands)
"HiCur" does flash on momentarily after switching bands.
There are no INFO ### messages.
My equipment for this test: OHR WM-2 (QRP) and Heathkit HM-2140 (QRO)
watt meters and OHR RFL 100 and Heathkit Cantenna dummy loads.
The testing steps during the KPA100 build checked out properly. I have
double checked the solder joints and reworked those that I thought might
have been questionable with no change in the (mis)behavior. I don't
know if these findings are of any help to you... I would be glad to
supply whatever readings as I may be able.
Troubleshooting suggestions appreciated!
Thanks,
