If anyone wants to see the projects, Bill has a list and files
Call for BOD Nominations. We need at least three nominations for the board to replace or retain BOD members, Floyd Glick, Dave Molter, and Bill Miller by Feb 3rd. Bill called Dave Molter this week and he declined to be nominated for retention as he is too busy to serve. Don Latham was nominated and seconded in the engineering meeting and Ray Uberecken and Floyd Glick were also seconded in the meeting. Later Bill self-nominated and Myron seconded.
Bill moves that nominations after this meeting will close and he will send out the election ballots in Email. This was seconded and Bill will send out the Ballots on Feb 23.
In 2019 and 2020 we accomplished a lot of the big goals that we had been working on for a number of years including (H1) Hydrogen Line mapping, Tropospheric scatter communications, Pulsar detection, and EME. Now that we have those accomplishments and can replicate them at will, we should look ahead and decide what we do next. Everyone should think of a radio astronomy or organization project that they think would be doable and important and get those into a list that we can review and go after with some more detailed plans. The main categories of interest would be:
New observation initiatives
Ham Radio capabilities, contesting and special events
On site open house for Aug 2021
Continued Infrastructure upgrade and maintenance.
Instrument and electronics upgrade and additions.
Scientific discovery, theory testing, and publication.
Educational programs and events for members and students.
Public outreach and member recruitment
There is an upcoming Schriever STEM Day on April 23rd from 2:00 pm to 6:00 pm. This may be an opportunity to gain some new members and is an excellent outreach opportunity.
If going to the site call Chad Carter to see if he would like to meet you there. He often works on the camera on the large grain elevator in Haswell and other Eastern Colorado sites. www.car-telenterprises.com 785-564-0118 cell.

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 with 52 members. Several members that we normally see at the open house and renew dues then did notdo 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 $2579.20 Savings Is: $5742.29, Jan 978.25 income and $471.73 expenses. Bob Haggart was reimbursed $360.25, Electric bill $83.77.

Update: the URL for the Amazon Smiles link is now at the bottom of the DSES homepage after the PayPal link. Use the URL: https://smile.amazon.com/. The site will then guide you. Select “The Deep Space Exploration Society” as the non-profit organization/charity.
Discussion on Phishing EMAIL. Getting a lot of 1 liner emails. Don’t open the attachments!
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,
So far, we have these nominations.
We have received only one nomination for BOD by Email for Ray Uberecken from Myron. Bill Seconded that nomination,
Floyd Glick self-nominated in this meeting and Bill seconded.
Ray nominated Don Latham and Bill seconded.
That is Three but to have a little competition we would like to have more and will hold nominations open for a few more days.
In keeping with the Bylaws schedule changes voted by the board in 2019 the rough schedule is as follows, To hold nominations open we will need to modify these dates by the delay.
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.
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.
April 3rd is the SARA western conference with papers already submitted. Deadline for papers for the August conference is the first of June.
The SARA Drake’s lounge is on Feb. 21st at Noon. SARA members should be automatically invited.
Rich wrote a paper for the spring SARA conference. Check out Rich’s SARA paper on “An Arduino Controller for the Yaesu G5500D mount”.
Rich is doing a MAX2870 RF signal generator paper for SARA and will post. The unit has a frequency range of 23.5MHz to 6GHz.
Last Pulsar trip was not too successful. Had some issues of the tracking SW driving into the electrical limit switches. One failure was caused by a power glitch. The second failure was unplugging the Ethernet Switch and losing communication. Resetting the power, limit switches and manually driving the dish corrected the error but when moving the dish, you should always keep an eye on it with the CCTV monitor or out the window.
To get beyond the 13 pulsars captured so far and find fainter ones, we will need greater dwell times and more bandwidth in the receiver.
Bill to do a DSES Virtual Open House presentation to the Front Range 6 Meter Group on Wednesday Feb. 10th at 7PM. This was completed and the recording will be linked on the website. This picked up a couple of new members, Jim White who was part of the original Table Mountain DSES and Paul Sobon the president of the Front Range 6 Meter group.
Late breaking news is that Everett Curry, W6ABM Assistant Section Manager/Oregon ARRL. Would like to present the presentation to the General Interest Amateur Radio Club in North East Oregon Thursday, Feb 18th.
The 1296MHz feed is now changed out to the 408MHz feed for continuing pulsar work.
Need to learn how to use the B210 receiver.
Need more dwell time.
Need a 10MHz reference source for B210.
See the Feed change schedule on the main website page this needs updating.
The HughesNet dish for internet service may be a dry hole. Ray and Rich had called the service tech to the site, but he showed up at Rays residence, so it didn’t get fixed. We need to look for other alternative Internet providers Myron has started to investigate this.
Need internet for SuperSids and Radio Jove, Magnetometer, Security System, Power monitors, etc.
Things to do
Check clean out and fix the Sump Pumps in the underground before spring rains flood the bunker.
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. Find internet provider alternative.
Need to remove Tumble weeds have piled up in the ramp.
Continue to look for more, higher (8 Ft) chain link fence to mitigate.
Clean the silt out of 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 the Comm. trailer wall.
Find the perfect focal point and phase center of the dish. See: Ruze formula. Could we characterize the dish surface for problems and accuracy to determine the loss from damage and weathering. Or, could devise measurement and reference system so we always place the feed in the exact phase center?
Ground the feed to the pedestal ground for lightning and static build up mitigation.
Fix old website to link to new one.
Facebook page link to new website.
Miscellaneous discussion on various topics, see the Zoom recording.
