Hi Greg,

OK, then good luck with the installation of your MF station. We can do a 
CW QSO then. I think you will hear me over that distance.
BTW i also have a home-soldered Elecraft K2, if i remember correctly the 
SN is 3002 :-) Mine has a 160m module and of course no SSB! :-)

73, cul, Stefan

That would be fine for a first try, just to get the touch and feel for the setup. The TRX should be good to go for WSPR. I am using a second TRX of the same kind, but with General Coverage RX and TX (1.6 to 30 MHz) and a 400W PA and a 0.35ppm Master-Oscillator, regularly for WSPR and JT9 without problems. The radio is reasonably modern, all solid-state.
> The TRP8000 system is modular, consisting of a Transceiver Unit (ca. 15kg), a Control Unit, and the Antenna Tuning Unit. The Units are connected to each other by Control cables that can be up to 50m long, a Remote Controlled setup is also possible. The Transceiver Unit has two separate output connectors, one for HF 1.6-30 MHz and the other for MF. In a typical Marine setup a Whip antenna of 7 to 30m of length is used for HF, and a wire of ~30m of length for MF. The HF and MF ATUs are typically installed at the feedpoint of the antenna, the HF ATU is in a weatherproof Polycarbonate enclosure, the MF ATU is much larger and needs a weatherproof housing.

> Your 20 m wire could produce WSPR decodes in a 1000 km range, if the wire it not completely sourrounded by trees and if it has some distance above GND. For CW you may need high power or a better antenna. But the question is if your TRX provides the frequency stability needed for WSPR.
> Is the automatic tuner separated from the TRX or do you have to feed the wire into the shack? In principal you only need a coil and a ferrite transformer to match the antenna to 50 Ohm at MF. The material is available from the net or local markets such as BAUHAUS ;-) Don't hesitate to ask if you need more concrete help/advice.
