SAQ transmission on Alexanderson Day 2023

[Alexander Hahn]

Hi, this was one of the best transmissions with a strong signal, as I was listening to
the Morse signals from Grimeton, which I can receive at home with my RSP1A SDR receiver
and my Grahn GS5-SE active ferrite antenna. Thank you very much and vy 73, Alex DH2ID

Copied both transmissions at Barn Island Wildlife Reservation, Stonington CT USA on Alexanderson Day 2023. About R3 during the first transmission in heavy static crashes on the Wandel u Goltermann AT-611 Selective Level Meter with a 200 foot trailing wire on ground (TWOG) antenna on the salt marsh. Static crashes were peaking about -80 dBm above nominal -110 to .120 dBm noise floor. On second transmission, used just the Volvo XC60 roof mounted 80 meter Hamstick mobile whip instead of the TWOG. R5 copy with much less static crashing, even though SAQ signal levels were down at -100 dBm or so.

The W u G SLM was powered from a LiIon portable jump start 12V battery and a 100W switched mode power supply 12V DC to 120VAC inverter. On the second transmission I used a 4 AH Ryobi 18V LiIon electric tool battery and a Ryobi 120 watt 12-18VDC to 120 V AC inverter. It only used about 25 percent of its battery charge in the nominal 1 hour I had the WuG powered up from it! No interference from the inverters on either transmission. The reception site site is very quiet, no man made electrical noise, the nearest power lines and residences are over a half a mile away.

What was RF power level to the antenna during the two transmissions?

Was SK6SAQ on the air during the event? I listened on 40 and 20 meters but did not hear any SK6SAQ activity here on the published frequencies.
Thanks to all of the staff at SAQ for putting on a great event!

Hardly heard in my noisy urban environment. I was happy to decode ….vvvv saq… with my homebrew tube superhet

Hardly heard in my very noisy urban city Hannover. I was very happy to decode “vvvv saq” with my homebrew tube superhet. The antenna is a longwire in the attic of the house. Please follow the link.

Tried receiving the 1400 CEST transmission and was pleasantly surprised to capture a readable signal through all the QRM (and supposedly some QRN) in the centre of Cologne.

I’ve put a text with some audio on my (German) blog:

Always fun to watch and listen. Thanks for your great work.

SAQ transmissions were weak but recognizable at Cohoe Radio Observatory at Cohoe, Alaska USA. A full reception report has been submitted.

Good signal here in JN48MM during both transmissions, using a Mini Whip at the roof top and an upconverter with S042P into an Elecraft K3. SNR was about 18 dB but it was somewhat more pleasant to listen to the transmission at 9:00 Z.
Thanks to the whole team for your effort and hpe cuagn.
