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.
