Hello Greg,

RR, then welcome to the group!
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.

73, Stefan

> Hi Stefan,
> Yes, I‘m new to the LF group. I started listening to MF/LF last winter and joined the group a couple of weeks ago. At the moment I use the Mini-Whip for listening, it is installed high up directly under a  roof without isolation. The RX/TX is a Marine radio mfg. ca. 1995 by Skanti from Denmark, Model TRP825xMF, 250W Max. Output on MF with an automatic ATU. But I haven‘t yet managed to get up a half decent TX antenna for MF. For HF I use a 2-Element Yagi and a 20m long Endfed wire. I own a few of these old Skanti radios and use them regularly on the HF bands, mainly for CW, but only one radio has the MF PA-Filters installed. The town here is called Rimbach, Loc. JN49jo, and I live right in the Center of it, so it‘s not the worlds quietest QTH, but not that bad either. Space for long antennas is limited, the house itself is big but the estate is small. I‘m open to experimenting, but I must confess that I‘m not the worlds most technical guy, having studied Life Sciences (Pharmacy) in Heidelberg and making my living by selling legal drugs (=Pharmacist)
