[600MRG] My TXing experience on 630m

[Tom W8JI]

Hi Neil,

I think you have significantly  more ERP than that. I would likely never 
be able to make a CW QSO unless we tried for days, but I think it is 
possible. You were about like a deep deep Asia station when they use 
100W on 160M. I would describe it as a few characters in a row 
discernible every dozen second mixed with nothing readable, but I don't 
have good RX antennas yet. It is just quiet here.

I don't have a recorder or rig connected to a computer yet. I have been 
mostly inactive.

I do have an IC7100 I am getting ready.  It looks like after some 
capacitor changes it can run 5 or 10 watts after I make a low pass. I 
posted some stuff on the QRZ LF technical forum. My 7100 needed four 
capacitors changed to start looking more "normal". Now I know the only 
remaining problem is the output transformer or feedback transformer or 
both do not have enough impedance. But it will work if I keep power low.

Five watts should get me near the legal limit.

73 Tom
