Membership Dues are now due for 2021. Please submit check or pay pal payment to Myron or on the link in the website. We started 2020 with 62 members and ended 2020 with 52 members. Several members that we normally see at the open house and renew dues then did not do so this year because we did not hold the open house. Myron has tried to contact them but have not heard anything back yet.
Latest Treasures Report from Myron Babcock. The current checking is; $2791.73 Savings Is: $5742.20 Electric Bill for 2020. $825.94 for electric and telephone. $337.56 to Steve and $335.81 for Glenn for materials for facilities and Tracking System.Bob Haggart submitted 12 receipts for construction on the Communications Trailer operating desk and separate workstation. He also built the wooden steps leading up to the trailer and did some electrical work inside the trailer for the electric heater. The total cost was $360.25. The Board approved this reimbursement.
Photographer, Marc Slover visited the site with Michael Rice on 12.20 – 12.21 and created time lapse videos of the site. They would like to do it again on a night where we are moving the dish for Pulsar or other observations. See the video at:
We elected 4 BOD positions in 2020. Myron Babcock – Treasurer and Gary Agranat – Vice President were retained. Steve Plock – At large, and Dr. Richard Russel-At large were replaced by Bob Haggart and Bob Sayers.
We will elect or retain 3 seats turning over in 2021. These are; Dave Molter at Large, Floyd Glick- Secretary, Bill Miller President.
We need to finish and post the new bylaws changes related to the BOD election schedule that was approved last year to our website. Bill sent the Ver 3.1 Bylaws markup to Gary and Floyd for review, incorporation and posting.
In keeping with the Bylaws schedule changes voted by the board in 2019 the rough schedule is as follows:
Open nominations now, January 15th, and close in 20 days, on February 4th.
Release the ballot to the members by February 9th.
Hold board election in the following 10 days, completing Feb 20th.
The 4 BOD members not up for election shall count the ballots and make results known to the membership by Feb 26th.
Schedule the “all-member annual meeting” in early March and in that meeting the Board votes for or assigns officers from the elected BOD. Although we would like to have an in person meeting, because of the Covid-19 and our responsibility to keep our members safe, the all-members meeting will be scheduled and held virtually.
Status of SARA mini H1 1420MHz Receiver kit containing a Sawbird LNA and SDR from NoElec with 2,4GHz Wi-Fi dish and mount with AirSPi SDR Sharp SW from Rich. The kit is on the SARA website. There is also a user’s manual on the site.
April 3rd is the SARA western conference. Deadline for papers for the August conference is in June.
The SARA Drake’s lounge is on January 17th for SARA members. There are now 2-3 80ft dish groups in the group.
The 12 ft H1 dish is working at Rich’s residence. Rich’s SuperSID receiver is broken. The 408MHz SDR receiver is up and ready for pulsar observations. The B210 SDR receiver from Don Latham is working at Rich’s Lab. Only missing the GPS connection. This can be connected to the GPS are the site.
Next pulsar trip; New members Dan Layne, AD0CY and Photographer, Marc Slover would like to attend the next pulsar trip. Please contact them if you are going.
Rich wrote a paper for the spring SARA conference. Check out Rich’s SARA paper on An Arduino Controller for the Yaesu G5500D mount.
Michael Lowe donated an Edmond Scientific 8 inch, 65 inch focal length optical telescope to the DSES. Bill started working to clean and refurbish the telescope to the original condition. Floyd offered some advice and assistance in collimation once the scope is ready.
Planet Walk support: Bill worked with the Planet Walk Org. and got some on air PSAs for them with KSTY, KCME and KRCC.
Dark Skies support: The DSES organization should support the Dark Skies initiative in South East Colorado to help extend the dark skies area for all astronomers.
Did anyone find Rodney Howe’s 1.665GHz feed? Looking for this still but Ray discussed his building of a new 1.665GHz OH feed he will share with Rodney. Rodney’s feedhorn is a copper cylinder about 5 inches in diameter and 12 inches long Keep an eye out for it at the site.
The 1296MHz feed is now changed out to the 408MHz feed for continuing pulsar work.
See the Feed change schedule on the main website page this needs updating.
Things to do
Check clean out and Fix the Sump Pumps in the underground.
Cut off the 5 band vertical mounting pole and move the vertical base to ground level and reattach and add more radials and bury them for protection.
Repair the dish edge damage.
Clean out the tower and the pedestal base.
Align Ray’s HughesNet Satellite internet dish. Call HughesNet for reprogramming and support.
Need to remove Tumble weeds have piled up in the ramp and add some fencing to mitigate.
Clean out the silt in the Underground from the flooding damage.
Nails on Road. Several of Ray’s friends came out on the 10/3 trip and used metal detectors and magnets to clear the site of nail and metal on the road. We’ve all had flat tires and need to continue to clear the road and site of debris as many of us have had tire damage. Bill bought a new magnet roller and left it in the Comm. Trailer. Please walk it up and down the road once whenever you’re on site.
Align the 3 element Yagi and re-enforce.
The Ham Radio Equipment in the bunker needs some dust covers or enclosures to keep the dust out of the equipment.
Need a program to combine logs for position and time and signal strength.
Need to modify the heater with sheet metal or plastic covers to provide safety and the bracket needs to be reinstalled. Need 4 2 ½ inch drywall screws to hold the heater bracket to the wall.
Replace the rear window of the Comm. Trailer. Complete: Bill bought custom window from Kent Glass for $81 and installed it.
Ray has 8 brackets to fix a railing around the scaffold for additional safety.
Ettus Research B210 receiver from Don Latham. Rich has it working except for the GPS input. Will work at the site with the GPS. Don says there is a 10MHz source in the electronics he brought down.
Retrieve Key for Battery Box from Ed Corn.
Clean up the DC Bus on Comm. trailer wall.
Need to characterize the dish surface for problems and accuracy.
Miscellaneous discussion on various topics
The GPS 10MHz 4 way distribution box that Ray built just needs a small power supply.
Ray would like to make a work trip on Saturday the 16th. Need to build the scaffold railing and add the U-bolts on the feed hub. This trip was cancelled for wind and other activities.
Bob says he will modify the heater with covers over the exposed wiring.
Skip Macaulay sent us the spectrograms of our EME signal in the first frame compared to others in the second as received with his dish and equipment in Lacombe, Alberta Canada. This clearly shows our excellent signal strength amplitude off the moon.

This autumn Dr. Richard Russel attended the Very Large Array (VLA) Imaging course in Socorro, New Mexico. The course taught how to take the data sets from multiple large interferometer antenna systems and produce images and science statistics.. This post presents the slides from the DSES Science Meeting on November 25, 2019. This is an update from Dr. Russel’s posts on the topic from October 19 and 31.
Dr. Russel also presents his September 2019 results of Hydrogen 21 cm (HI) drift scan measurements at his newly installed 9-foot dish antenna at his home in Colorado Springs.

Steve and I went to the project. We had perfect weather.
We got the messenger cable between the tower and dog house up, and we got the coax cables strapped to the cable. We dressed the cables in the bunker with the cable end for the Tribander at the radios. Steve turned the radios and made a contact with one of the islands (a 9Y, Trinidad and Tobago) on 15 meters. He also made a 20 meter contact with Mississippi. The Tribander is working well.
I put the batteries in the new CO detector and left it on the desk with the fire alarms. I will complete the install on the next trip down.
Steve has pictures of the messenger cable and the used gas grill he picked up. I fixed the grill’s electric igniter.
The Deep Space Exploration Society will closely participate with this year’s Western Conference of the Society of Amateur Radio Astronomers. Conference talks will be given on Saturday March 23. On Sunday March 24 conference participants can travel to visit the DSES radio telescope site in Haswell, CO. A hotel in Eads is available for staying overnight. Registration is open until February 25, 2019. Below is an announcement we received to pass on.
