We happen to be at a good time in the sunspot cycle. The sun is at or very close to the bottom of the current cycle and between now and 2011 propagation on the higher bands will just get better. I've

Yes, IMHO there is. Wrong. You are assuming that a narrow SSB filter, which COULD be, WOULD be. Quite simply it would not. So a user would be able to recieve CW in USB mode with a 2.4 kHz bandwidth.

It depends upon the price difference. Since the rig I imagined had a digital synthesizer as its signal source, it would have to be "pulled" to transmit. In plain English if you used a 455kHz IF (as c

I was the one who said that, and I still stand by it. I was refering to an HF radio targeted at new hams who do not know morse code. When you learned to copy code, 15kHz was the current technology. N

What filter would you say is needed? 15kHz? 2.8kHz? 1kHz? Bear in mind that the radio is being targeted at hams with NO CW skills, and probably no desire to learn it or pay for it. I did not say it s

You still need some sort of connection to it for relatively high speed data. This would most likely be a cellular data modem which is not cheap to buy or use. WiFi might work, but you need to be in a
