Depending on your feedline, that might not be a lot of power--you could lose 10 dB or more signal doing that, so you sound like 2 watts instead of 20. You may have more luck answering stations at that power level. Around 50 ft of RG-58 or 75 ft of RG8X will do that. You may be able to get reports on

One of the few programs that will run on lots of different operating systems.

You can also buy plug and play interface options between the computer and radio.

In practice, it is better to use a "native" keyboard mode like PSK31 than to use CW as a keyboard mode.

[color=blue]An inverted V isn't likely to help unless you get it much higher.

Making QRP contacts on SSB is hard--it is even harder in the middle of the summer when many hams have other activities. Band conditions are better in the Spring and Fall--so is activity.

Contests can be a good time for a QRPer to make SSB contacts--stations build really big antennas so they can work as many stations as possible--experienced contests will dig for weak stations when things slow down--the 2nd day can be very good for QRPers if the band conditions are good.
