With numerous band openings, I decided to try QRP today on SSB.

I made calls using my call sign, followed by telling them "QRP". I was able to work 7 countries, and had a blast!

I used HRD to turn down the power to 5W at the rig. With about 200 ft of coax, I am probably closer to 3-4 watts at the antenna.

Please let me know if this was done correctly (call sign ID and power calculations). I am keeping a separate QRP log. Looking forward to more.

Yep - signing QRP following your call is a good idea, and does help bring in the replies.

Whether or not your calculations are correct for the power at the antenna is correct depends on a lot of factors.  The two most important on the operating frequency and the type of coax.  Each type of coax has a different amount of frequency dependent loss.  The specs you find will typically say something like "2dB per 100' at 30MHz" or something like that.  Loss goes up as frequency goes up.  So, you'll have lower loss on 160 or 80 vs. 15 or 10m.  Your numbers reflect about a 1 to 2dB loss, which is probably reasonably close if you were operating in the lower HF bands, into a matched antenna system, with some decent coax.

You think SSB is fun, try CW or PSK.  Good luck and keep it up!

I've hit the east coast from the Oregon Rain Forest with about
one milliwatt into a 19' tribander and WSPR.  I have not gotten across
any ocean yet on 1 milliwatt (0 dbm).

I do not have a QRP rig. So I can only get to 5 W.

What's HRD??

Ham Radio Deluxe
An amazing FREE rig control/logging program with too
many features to list.
HRD also includes mapping, satellite tracking, DX Spotting,
and the digital mode program Digital Master 780 (DM780).
DM 780 will let you copy and send dozens of digital modes.

Try it, it's not for everybody as there is a fairly
steep learning curve. But oh boy, once you get it going.....WOW.
