Preliminary Baseline 420 MHZ Celestial Drift Scan Survey, December 2016

Here is my fist shot at a survey! A lot of things I can fix for next survey, planned for after Christmas.

1) Will have a 15dB preamp installed on mast
2) Will raise frequency to midrange of antenna sweet spot (435 MHz)
3) Will do a better alignment of antenna

This was fun!!!!!!

New Milky Way H Map – Incredible Detail

Sky & Telescope has a short, illustrated news item today about high resolution 1H (atomic hydrogen) observations of our galaxy from Australia and Germany. It includes a video showing how the view changes with wavelength due to Doppler shift. I thought this would be good to share; this is what we’ll be looking for with the HI drift scans.

Radio Jove and SuperSID Data and Analysis Reports

Attached are the August reports for the Radio Jove, located at Plishner, and the SuperSID, which is located at my house.

1) The Radio Jove observing season is closing down with only an hour of observing time a day after sunset. We did get a couple of probable hits.

2) SuperSID did detect an M1.3 flare on 8 August. I also conducted a comparison of the Radio Jove results and the SuperSID results. I found no significant correlation between the two telescopes. The lightning storms this month also affected both telescopes by adding a lot of spurious signals.

I have been in contact with the Radio Jove NASA coordinator. He likes what we are doing and has provided information to improve our Radio Jove system.

DSES Perseid Meteor Shower Open House

Deep Space Exploration Society

Perseid Meteor Shower Expedition 2016

DSES conducted its first open house on Friday, August 12, in conjunction with the Perseid Meteor Shower. We had 11 DSES members and over 20 guests spend the evening looking at Saturn, Jupiter, Mars and the Moon through telescopes while watching for meteors at the Plishner Radio Astronomy and Space Science Center in Haswell, CO.

We had five optical telescopes on site for viewing of the skies as well as lectures from 2 Pikes Peak Community College astronomy instructors who provided instruction on the use of the various telescopes present.

We had a few glitches such as the mice eating the wiring in the generator controller which shut down the main source of power for the site. However, thanks to some quick calls, Dave and Bill were able to get a generator shipped down to the site. This generator powered the site for the next two days while Ed worked out how to fix the primary generator regulator.

Special recognition for Don and Adam who traveled 4 hours to attend the event. They also spent many hours clearing the bunker ramp of tumbleweeds.

We had four or five optical telescopes set up for everyone’s viewing pleasure and some of the local community came out for an impromptu start party. Everyone had an educational and great social time together.

Kevin Ahrens and several other photographers came down and shot some amazing photos and time-laps videos of the storms rolling in.


Gary Agranat organized and manned a special events Ham station and collected 86 contacts on several different bands during the event.  This was the first major use of the DSES new Club Station call sign, k0prt (prt stands for Plishner Radio Telescope). New QSL card were made by Kammie Russel, the daughter of a DSES member.


Much progress was made in outfitting the dish and getting control set up.


Many members stayed overnight at Diane’s Park which is under the 60 foot dish.



Ray and Floyd prepared a 6 meter antenna for the meteor detection radio telescope. The communications van was outfitted with extra antennas for 6 meter ham radio plus UHF and VHF amateur satellite communications. The van also has a 6 meter to 180 meter dipole for HF communications.


Bob counted sunspots and solar prominences using the solar telescope lent to DSES for this event by Pikes Peak Community College. A star party with multiple optical telescopes was a big hit while watching for meteors.


Myron set up an AMSAT communications system in the communications van.


The neutral hydrogen experiment was installed using the SpectraCyber system. The dish was moved to accommodate the new advanced feed built by Ray. The feed will be permanently mounted on the dish in the next couple of week. This will allow for UHF, VHF, 1296 MHz Earth-Moon-Earth  (moon-bounce) and 1420 MHz neutral Hydrogen radio astronomy.




The next expedition will involve using the new antenna feed system for the ARRL Moon Bounce contest in the October time frame as well as the first use of the primary dish for the neutral hydrogen radio astronomy experiments.

Plishner Open House Weekend August 21, 2016


I set up our eQSL account and created an eQSL card for us. I then uploaded our log file from our weekend QSOs. I attached an example of our eQSL that goes out to our contacts. (In this case it is to Myron, who gave me a call from his radio.) We had 86 QSOs. 9 eQSLs from the weekend were already waiting for us in the eQSL inbox.

I will attempt to set up an ARRL Logbook of the World account for us this week. And when I have a chance I will provide an update to Steve for the QRZ page, now that our weekend activity completed.

Also when I get a chance, I’ll email my photos from the weekend to Bill.

DSES Open House 8/12 & 13

DSES will conduct its first open house this weekend, Friday, August 12 and Saturday August 13, starting at 5 PM on Friday. The Perseids Meteor Shower event should be at its peak this weekend (after midnight) with an estimated 200 to 300 meteor’s per hour.

We should have several optical telescopes on site for viewing of the skies. We will have radio equipment on site for all our working science projects. A ham radio station using the new DSES club call sign K0PRT (Plishner Radio Telescope), will be on the air on several High Frequency radio bands. We also hope to have an amateur radio Oscar satellite station working as well. Our big project for this weekend will focus on installing the new tri-band dish feed. If all goes well with this installation we hope to bounce a 1.2 Ghz radio signal off the moon and be able to hear our echo 3 seconds later.

For those who may want to spend the night, please bring your own sleeping needs. We should have floor space in the bunker for your cot/bed. WE DO NOT recommend sleeping on the floor in the bunker at this time. We have lots of parking space for RV’s, trailers, or trucks/cars. We will start grilling hot dogs around 6PM Friday. Be prepared for hot temps during the day and thunderstorms, rain, wind and maybe hail during late afternoon or evening. Mud boots may be nice to have if it rains.

The Plishner site is located at 9301 County Road 20, Haswell, CO or 4.8 miles south of the town of Haswell, CO.

Call me if you need directions or further information on this weekend’s events. Hope to see you there!!

Report of August 7, 2016 Plishner Site Trip

Steve and I (Ed) made a work trip to Plishner Sunday 8-7-16. There were several changes in schedules this weekend, but Steve and I decided to go down and get done what we could.

We arrived at 10:00 AM, opened the bunker and it was dry. The big trash can out side of the comm trailer had .3 to .5 inches of water in it, less whatever had evaporated.

Steve power loaded the 160 meter dipole at the bunker on all bands, so the raised height has helped. Given Steve could load the 160 dipole, he did not use the 80 meter dipole. He will load and prune that at a later date.

Steve then checked the voltages at each battery pack and compared them to their read outs. The delta on the bunker voltage meter is 2.2 volts for full charge. A voltage reading on the others of 12.1 or better volts indicates 95%+ voltage charge.

Steve and I installed the second air conditioner in the comm trailer. With approximately 2 hrs of running both air conditioners, the inside temperature was 11 degrees below outside temperature. When using the air conditioners, you must keep the side door closed and limit in and out.

Steve took caliper measurements of the pass through hole in the top center of the pedestal for Dave.

I started investigating the 2 dead generator plugs in the comm trailer, and found they route into the mechanical area at the tongue end of trailer. I will investigate and fix next trip.

We ran the generator for approximately 6 hours with a short load and encountered no problems. We secured sight and left at 4 PM.
