[TenTec] What Radio?

[jack]

I agree totally. I have 100 W and know that any boost would have helped in 
several cases over the years. I have missed considerable DX because I could 
not increase the power. there are many stations I have heard but could not 
hear me due to QRM or QRN.

The notion that there is no difference between 100 watts and 200 watts is 
flawed. There is a little over 3dB difference, which often makes the 
difference between a QSO, albeit a rough one, and no QSO at all. I have many 
QSL cards that I would not have, if I had been limited to 100 watts.

I've tried it over and over. When the band is just coming up or going out, 
when the QRM or QRN is high, I've switched between 200 and 100 watts, and it 
made the difference between being copied and not being copied.

Signal to noise ratio depends on the signal strength and the noise power. If 
100 watts puts you at or just under the noise level, 200 watts will result 
in a copyable signal. True, if 100 watts gives you S9 at the distant end, 
then 200 watts won't make any useful difference. But most of my DX contacts, 
especially the rare ones, have been other than S9. If you choose to operate 
100 watts for the challenge, good for you. But there is a difference.

In addition, when I run 50 watts on RTTY with a 100-watt transmitter, I have 
to be very careful about duty cycle and giving the finals a rest. When I run 
50 watts with my 200-watt transmitter, I don't.
