No new special events are scheduled at this time.  We do sometimes operate casually, especially on some weekends. Also, some members like to participate in nets on 80 and 160 meters.  If we operate digitally for a while, we may spot ourselves on the DX cluster.

Amateur Radio at the Deep Space Exploration Society

The DSES amateur radio club call sign is K0PRT (PRT for Plishner Radio Telescope).  In addition to our radio astronomy work, we have begun to use our 60 foot radio dish for ham radio EME moon bounce and tropospheric scatter. We operate on the amateur high frequency (HF) bands as well. And we have a 2 meter-band VHF call-in system to talk locally.

For antennas, we have on the Haswell site a 3-element tri-band (10, 15, & 20 meters) Yagi antenna on a 50-foot tower, a 5-band trap vertical antenna, and dipoles for the 80 and 160 meter bands. For the 6 meter band we have a 3-element Yagi and a wire delta loop.  On top of the 50-foot tower we have a VHF vertical antenna for our local 2-meter band call-in radio system. 

We operate for specific projects, as well as casually for fun.  We do special events.  And sometimes we participate in contests too.

We periodically upload our logs to ARRL Logbook of the World and eQSL.  We also respond to traditional QSL cards by mail.

If you contact us on the air and would like to receive a QSL card, please send a Stamped Self-Addressed (SASE) envelope, one that can hold a 4 inch x 6 inch card, to our new address below.  Please include your QSL card if you have one, or the QSO information for verifying the contact.
