NAC 6 November 144MHz

 Again good tropo   and a long m.s. FT8  burst 1734km  to YO3YKT this burst was 1903Z and noticed by more local hams must have been a bigger meteor, that is the advantage of FT8 mode events like that will be noticed with so many observers at 144.174   Strange enough the 144.174 was overloaded with signals but no one went to FT4 or an alternative frequency as this is the procedure at 6m and HF. VHF UHF amateurs in general are old-fashioned  in operating technics .. Also rarely PC logging or LOTW  is used by VHF/UHF hams .. but FT8 yes most do .. Everybody likes doing  CW the real mode  but in real activity events ... not... best 2-way EW6FS 1334km   Red =6m pink 28MHz And at 432 MHz  SM0KAK FT8/ CW    SM3LBN  -6 did not hear my 25W / 23ele signal 40W -3dB cable estimated at 432 MHz   FT8 SP2WRH CW SP2HMR

144 MHz MMC Marconi Memorial CW contest 2/3 Nov 2024 exceptional propagation

   Very busy CW band during the Marconi CW  excellent propagation. The N1MM bandmap was filled from 144.0 to 144.150 rarely seen in the FT8 era.. First time used the Flex6500 plus the Ukraine UR3LMZ setup as in my previous post. That worked very nice, the Maestro as control. Doing  only S&P no CQ runs, wtKST was on so I was open for skeds.  I did cherry picking and there where lots of cherry's on.. The result is a very high average distance 733km over 85 QSO on 2m. A full contest station of course  should work al stations on the band. My tx signal was clean I could come very close to competitors without IMD or reciprocal noise. So the Ukraine transverter is excellent as long as its internal l.o. is not used. And the Flex has very low  internal noise. I use an older SSB LNA close to the 12 ele  dual band  Antenna & Amplifiers. This SSB LNA can handle max 400W  it's nf is not extreme low measured about 1.7 or so at144MHz But it really makes the difference especially at 7

50MHz najaar F2 openingen

 De afgelopen week  veel Japan en diverse VK6 27 November zelfs oost VK  VK2IR  korte opening  LOTW bevestigd d 6m beam DK7ZB verlengd to 7ele 9m30 misschien heeft dat nog iets geholpen tot nu was VK2IR de beste DX verder lijkt niemand me te kunnen horen of zien ook niet met de ACOM1000 er bij aan er komt geen hond retour!     Nieuw DXCC was Vietnam  Eddi Visser XV9T  FT8 en USB vaak gezien en  3W9A ook 1 ochtend YB5QZ en 9V1XX  Singapore na 30+jaar +  nu in FT8 mode VK6TM VK6ZLX VK6DU VK6APK  regelmatig te zien  De meeste DX word gemeld in de JOx0 zone  100 -200km zuidelijker     VK6ABS in SSB   4S7AB en DU6/PE1NSQ  ook gezien  maar PSK krijgt niet alles mee

144 UR3LMZ XVTR with Flex6500.

  I wanted to receive 2m with the good band panorama of the Flex6500. This offers  a different experience seeing what happens on the band without tuning all the time. Also at HF using split the pan adapter is very useful. My IC7100  performs very well at 6 4 2 and 70cm but it lacks the panorama view. I tried RTL dongle and SDR-Console  but connecting the RTL dongle behind the preamp without affecting the 144 reception was not as easy as I thought. I got extra noise when connecting the 2nd receiver.  Also tried N1MM with pan driver but I could not see the signals  I heard it should be the other way around ? possible I did something wrong. Tried an old DEM 144 but that is a huge box with Xtal oven and relay T/R switching. 12V 0.4A and start 1.5A to heat up I still owned 2 so called Ukrainian transverters , very small footprint 40x80x20mm nice build low priced.  low standby power 30mA/12V (real),  SS T/R switching no relay's.  As small as it is it brings 10W rf from a RD15HVF1 high ef
