I got a pleasant surprise yesterday when K3 457 arrived. It was ordered
June 13 and I got my Lisa Gram last week end.
It has KAT3, KBPF3, KXV3, 500 hz filter, 2700 hz filter, 6000 hz filter
and the FM filter on back order.
I made a special test on it because I wanted to know how the KPA3
changes the current draw. I know others have asked
the same question here and never did get an answer so here it is. .
The current tests before I put in the KPA3.
Receive 0.94 to 1.1 A
TX (NO POWER) 1.56 A
TX 5W 2.56 A
TX 10W 3.07 A
TX 12W 3.23 A
The same test after the KPA3 was installed, Set up and working fine.
Receive 0.94 to 1.1 A
TX (NO POWER 2.16 A
TX 5W 3.10 A
TX 10W 3.62 A
TX 12W 3.78 A
All the above testes were done with a digital meter on the 10 amp scale.
I would say the KPA3 adds a constant 0.6 Amp for any given power level
below 12.1 Watts.
I started the inventory last night about 6:00 PM and finished it tonight
about 8 PM. I had a fire run, slept, went to a meeting etc.
so my build time must have been about the magic 10 hours.
I sure do like the receiver but have just scratched the surface of what
it can do.
It was worth the wait.
