Morning Marinos,
Very interesting thoughts. There must be a huge pool of technical knowledge
and practical know-how amongst Elecraft's customers, a powerful combination.
Now if we could also eliminate storm static QRN - a tough nut to crack !!

My KX-1 #00278 was recently built by Alan, W1HYV.
Even though his meticulous work was completed within a week Alan kept me
informed of the building progress.
All of the KX-1 features operate perfectly; my unit includes the ATU, the
30m module and the paddle.

N connectors, while constant impedance, have their own problems. Biggest
of which is the disconnection of the center conductor when the coaxial

In Finland N-connectors were used in mobile network antennas in towers

I've been in touch with Kevin/KD5ONS, and I'm going to try spearheading a 30m
version of the Elecraft CW Net Tuesday evening (UTC Wed) from z-0100z on
10115 +/- 2kHz.
30m is (in my opinion) one of the best bands to operate QRP because it has less
noise than 40m, and just about everyone is

On paper, you're right. For the vast majority of
hams, N connectors are silly.
However, there are many other considerations of
station design that influence connector choice.
Most of my connections are outdoors and my station is
built with nearly 100% hardline. All cables can be
used
My SO2R contesting setup just replaced an FT847 and

port. A homebrew bit of hardware does the keying and
PTT generation for both radios. My previous setup

The old rule of thumb for an old dry cell providing 1.55 volts is based on
the materials used, not the age or condition of the cell. A zinc-carbon cell
produces very close to that voltage as long as the chemicals hold out.
What changes with the aging of those cells is their internal resistance.
Ron:
Very informative.
Thanks,

Roger,
I am interested in buying the LDG RT-11 and control head.
Would you take paypal or a Canada Post Money Order?
Would you ship to me via US Postal Service International Parcel Post (Air)?
Is the RT-11 factory built or built from a kit? Condition?

The major changes between your K2 (sn 3000+) and the current one is the PLL

minor change is the addition of diodes D40 and D41 to handle strong
