first qso’s on 4M

This morning excellent Es on 4M to ES en South OH. Although I only have 25W , 20 meter RG-58 (about -3 db) and an open dipole, I managed to work 8 stations also new DXCC’s, although the ARRL is not into 4M/70MHz yet.
Real sporadic E: either you hear&work them, or not.

Working with the transverter is OK, but using the Flex-1500 with PowerSDR is not easy. The waterfall display is nice but tuning is something to learn. And only USB for tx because my key is connected to the HF-set.

So I think it is better to change to another setup: TS-2000 in transverter-mode, N1MM in transverter-mode. Then I have all the benefits of the integrated workplace, logging, macro-keys in N1MM, RTTY (or Iscat or whatever).

The 4 ele LFA-beam for 4M is still under construction. First some parts were missing and now the rains have ‘improved’, monsoon time. I still have to tune the beam and that is something to do outside…

Yesterday there was Es on 2M, only short openings but good distance to UC6A (2500 km, new locator-square) and US8ZAL. Overall Es on 2M is not that good in this part of EU, the Aurora is to strong. Today a new CME is arriving so I assume Es will go down again.


qrv 4 meter: to late!

I decided to go for 4 M/70 MHz and use my flexradio-1500 as input for a transverter. I was very lucky to find the ME4T transverter in the online-market, only 10 minutes after putting my add the deal was completed! And a dipole for free, tnx PA2DW :-))

But setting up the transverter was more complicated than I thought. After opening it (yes, every radioamateur opens a box he just bought!) it was clear that the input attenuation was already there (a variable resistor) so my input of 0 dbm (1 mW) was not enough to get any output… But I only found that after a long time of trying, measuring, reading the manual (which was very old and not up-to-date with the inside of the box).

Alas, now I have 0,5 W input for 25 W output on my dipole. And no conditions on Es whatsoever, Aurora rules. To late for this season..

Next project will be to connect Flexradio-PSDR to N1MM via virtual ports & VAC. It just started to rain (normal Dutch summer) so time enough.

Long time ago

I was writing about ‘best Es ever’ last week. But then I remembered that in the old days we had a few big openings too.
Digging out my logs I found some nice Es on 2M openings in 1989.  Also in the top of the suncycle!
So sun-radiation destroys MUF but sometimes there are huge clouds with high MUF and staying long.
Lots of Ukraine and Eastern Europe and UL7AAX (Kazachstan) as odx. I was just seconds behind PA3CEE who scored the first PA-UN.

Note the old locators! (Much better)

I hope the pictures are readable, click to enlarge.

Best Es ever on 2M

July 1, 2012.

Es on 2M starting early in the day (9.45 utc) but to far away from us. But on the day the cloud is moving, splitting, coming together again, moving again. And all the time the MUF in the centre of the cloud is above or near 144 Mc, sometimes up to 200.
It lastest until 17 utc, 7 hours of Es on 2M. Incredible.

In Holland we didn’t have much luck with this day, the NE part got some short openings but nice DX. Very patchy, very local, deep qsb. Worked stations:
R7YY in LN04, in cw. Came up a few times in JO33. DX with 2600 km!

A complete view of the day on

I must say: operation skills on VHF are quite bad compared to HF. Repeating report a few times five-nine en complete locator takes loooong (sometimes even the name..), with patchy openings opportunities for others are destroyed by these ‘skills’.

For 6M I ordered a preamp. Last week there was a big opening to JA&HL but it was impossible to hear a beep here while PC5C, just 7km away on the NW from me, worked 30+ stations. To the NE (=direction JA) there is a big city but I don’t believe that is a problem (8 km away.)
During the opening I connected a homemade pre-amp which improved reception quite good. But no relays system  so unable to transmit. SP-6 preamp from SSB is coming this week, just in time for some more SSSP openings (I hope).

And if the sun improves (SFI rising fast) than maybe some F2 openings in autumn!
