DAC 70MHz

3 rd Thursday this month 70MHz  RSGB  / DAC contest

see what can be catched with my 2 ele 4m   of   3 band  VHF246  DK7ZB
Band was noisy here  local carriers sort of digi QRM
But  signals present in this normally very quiet band.

managed 10 QSO    in tropo scatter propagation

DAC 23cm

Image
High activity at 23cm  3rd Tuesday evening during the DAC  
My guess DAC stands for Dutch Activity Contest organised by the VERON
But EU wide activity every month 3rd Tuesday evening starting 17:00
After the May IARU contest this was the next good opportunity to test my 1296 GHz station.
And it was a success this monthly evening activity contest is very popular.
remarkable strong signal from SK7MW real 599 CQ-ing

My 23cm setup 120cm dish with  frontend transverter.  On top DK7ZB 642 VHF  below 5e6m +HF


                                            attempt to make a night picture  of the digital readout top-light.

                           The front end transverter DB6NT  + PA 30-40W ,  preamp eBay SPF5189z                                     PLL DF9NP 1150 MHz  not yet climatized 3 cables down:  28meter   RG58  3x1.5mm 230V    UTP for T/R and measurement      148MHz i.f. to the IC706 classic

Off season low band

Thunder storm   nice spring weather temperatures  20C

                                                 80M

still the  West Beverage is in the field
last night was not bad but missed sunset gray line due t-storm

WSPR 1296.500 MHz

test with Jorgen OZ7IT was success even ON5KTO was received  over 651km

VERON IARU mei contest

zaterdag gast operator bij PI4GN op 70 23 13 9 6 3 1,5

zondag  vanuit huis op 23cm
hoge verwachtingen voor mijn 23cm station
maar uiteindelijk slechts 9 QSO

behalve PI4GN 9++  en DF0MU geen signalen te horen

De dagen ervoor sterke WSPR signalen van o.a. ON5KTO en PA0JME
Maar geen spoor van al die PA's en ON's die ik verwachte
waar zijn toch al die om's  met die Bulgaarse  23cm transverters ?

23cm   WSPR  ON5KTO  first decode ever at 1296.500 USB
lots of Doppler airplane reflections

Have to isolate the PLL 1050MHz pll
Now it is drifting a bit and 100Hz lower then at room temperature

the IC706 reports the 146.501500 MHz i.f. at WSPRnet.org
WSJT-X can report the 23cm TX frequency if the i.f. offset in my XVTR  -1.150 is set
nice feature  this is not possible in N1MM+  as far as I know
 UHF contesting  often using transverters  that would be a nice option




1296.830 GB3MHZ  JO02pb  signal here with airplane traces all over
USB dial 1296.828400  (i.f. 100Hz too low )


QRV 23cm/ 1296 MHz again after 30 years....

"mast head" placed close behind 1m2 dish in plastic box (ACTION 1€50)  XVTR  1.5W , PLL 1150 DF9NP ,   PA PE1CMO  30-40W rF ( hoping) pre-amp  SPF5189z eBay  lowered to 2V7 still draws 160mA ! I replaced the original SPF5189z because it almost looked like short circuit  at 5V an UA78L05 could not supply it! needed a UA7805 200mA+  PCB heath up  need a better quality SMA - N  adapter   first QSO with  local PA0T very loud 9++  After 30 years  back on 23
                                          yesterday evening in nice temperature and no wind finally.
 A good time to place the disc + XVTR up
The modified DB6NT with PLL 1050MHz l.o. that was prepared last year up in the mast for the real test.
In JO33HG  could copy  4 beacons reasonable almost 100%
