Image:  Tony, KB7U, raises his antenna

Here is Tony, KB7U putting up his antenna.  He does a lot of satellite work, and presented a satellite forum at our last Hamfest.

Image:  KB7U on PSK-31 and 10 meters

Besides satellites, KB7U likes to run PSK-31.  Tony is here on 10 meters.

Image:  Lots of trees

We had lots of trees for antenna supports and shade.

Image:  Myrna (KN7M) and Tony (K7AJF) talking

That's Terry's Myrna, KN7M chatting with Judy's Tony, K7AJF, over in the left tent, and I believe that's Tony, KB7U under the other tent with the radio. 

If you increase the gamma correction in a photo editor like IrfanView, you can see the faces in the shadows.  These pictures are unedited.

Increasing Gamma Correctiun is similar to reducing Contrast and adjusting Brightness to some degree.  Increasing Gamma on this picture will reduce the range of contrast between the sunlit areas and the shadow areas.  If shadows are too deep, gamma correction will only bring up sparkles and noise in the picture's darker areas.

Image:  Tony, KB7U, with a laptop computer and PSK-31

Tony, KB7U, has his trusty laptop out on the table, running PSK-31.  That's one of many new digital modes introduced to the CW bands over the last 30 years.  it is so named, because it uses Phase-Shift Keying, and only occupies 31 Hz of radio spectrum.

Showing on the computer screen is a spectral view (dark area, lower right) of signals in the receiver passband, with a printout of incoming and outgoing messages above, and with two columns of possibly menu options to the left.
