We're feeling good about K2 # 5422 operation - it
seems to receive well, on a good day on the ham bands.
I've
gone over the "Transmitter Alignment" page 77 several
times. And we have an analog-meter MFJ AT on order.
I'm wondering if I haven't gotten some of the
variable-L's, like L3, L4, ......, L12, and L13 -
off tuned and their cores too high or too low, putting
them in false peaks?
When going thru the page 77 K2 "Transmitter Alignment"
steps - some of the coils have very minimal peak areas
- perhaps it will become more evident when I get an
analog meter in the dummy load coax line.
QUESTION 1: IS THERE A KNOWN DISTANCE, "inches", that
all of these RF Board "Toko Variable Inductor"
E690002, and E690001 inductor cores are set - from
factory? 1/4", 1/8", top, bottom, center?
1 or 2 of the inductors - I believe we have the core
screwed very high up near the top of the little can.
For something as serious as receiver/transmitter
alignment of my new K2 - I'd have a better feeling,
knowing I really have the whole circuitry peaked
correctly. And just "looking at a varying output
wattage level" (which jumps up significantly
sometimes,
and then settles back down, on tune/no tune) - on LCD
doesn't give me a warm fuzzy.
QUESTION 2: If I install the SSB Option NOW, will
that mess up my ability, to repeat the
receiver/transmitter alignment steps? I did install
the NOISE BLANKER
yesterday.
Thanks,
Fred N3CSY
K2 # 5422 --- 40/20 sounded great on CW yesterday.
