Pete,
this spring I started on 500kHz with a 9m high / 25m long lazy-L antenna
and 100W TX power (abt 300mW ERP).
I worked GM4SLV (Shetland Islands) at over 1000km and was heard in OH at
1600km.
So if you get the 70W properly into antenna it should be a piece of cake
to work you.

Hi Rik and LF
You have caught me out on ERP because I don't know it has not been
measured but my TX was measured at about 60/70 Watts into a dummy load of
70ohms about 200volts P-P across the load. The ant tuner is currently
unknown impedance but will match into the TX poorly so I hope to raise
the ERP later with a better match. The ant is a Long wire up 12metres and
40metres long (Horizontal) with an "H" ground wires. Up
wire in centre of "H". Will do some measurements when I get
back from break when I hope to work you. And many thanks for the interest
and support.
must go now 73 petefmt.. VA

- Hi Pete,
- what power / ERP were you running ?
- When conditions are good (good propagation, low QRN) 10mW ERP should
be enough for a basic CW QSO.
- Yesterday a QRSS QSO was possible, your signal was a solid
"O".
- BTW: last night I was running 270W output power, antenna current
2.15A. The calculated (simulated) radiation resistance is 0.42 Ohm and
the antenna "gain" 1.4dBd, so my theoretical ERP was about 2.7W
(close to the legal limit of 5W EIRP), but I guess that quite a bit of
power is absorbed by the greenery surrounding the antenna. So the real
ERP might be something like 1.5 to 2W ERP.

- Yes I have been running short QRSS sessions with my new higher
powered TX so hopfully it was me. I will be out of the loop for about 7
days but will look out for you when I get back. My CW is poor so it will
be rubber stamp if we make a contact. I have heard you working G3XIZ in
the past he is located about 14km from here.

I saw "FMT" in QRS earlier tonight, was that you ?
- The signal was very weak audible.
- QRN was rather bad (and going worse over the evening), with low QRN
- a
- QSO should be possible.
