Let there be audio

Quick hack with an LM-386 for an audio amplifier I needed for one
of our rooms.

From this:

Then this:

And finally found an enclosure:

Signals looked nice and clean on the scope and sound is sufficient for it’s
purpose.

ARRL June VHF+ Contest

And another VHF contest in the log. Did much better this time. Of course if
the 70cm beam would have worked properly the score could’ve been better.
Ah well, there’s always next contest. Fantastic opening on Sunday on 6m into
California, Mexico, and Texas!

Band   Mode  QSOs     Pts  Grd
    50  CW      25      25    7

CQ WPX CW May 2015

And another one in the books .. err .. log. Had some more time this weekend to spend
working in the contest but as usual could do more. Lesson learned: need a better antenna.
It is kinda fun to geek out with the statistic function of N1MM+.

Wiring cleaned up

Finally finished the new antenna cabling with proper grounding
and no more RG8x (for the most part). All cables now enter the
house through a nice and clean box and all except the dipole use
LMR-400.

NAQP RTTY in the books

Didn’t have much time to operate today but still managed to get a few
QSOs in the log. For fun I played with the statistics in N1MM+.

New FSK/CW interface

Took some time tonight to re-build my FSK interface for the TS-2000 and
add CW keying for the upcoming ARRL DX CW contest. Looks much nicer
now.

Also had to made a pig tail to get all the signals out separately to be
able to use it with multiple radios.
