It was nice to meet again with the hard-core-dxers TUA, JVA, JSN & JPR at Oulu and Muhos (JPRs super QTH). Once again our Sun celebrated our meeting with a rapid rise of solar wind on Feb 27 causing a sudden decline of mw-propagation!
This has occured every time at our meetings during several years - so that was not a surprise!
We started the meeting at Oulu with nice meal at an old storehouse on an island "Pikisaari" near the city center - at "Sokeri Jussi Inn" with nice beefs and some wine and beer. Indeed the Inn´s recommended Red Wine of Spier, South Africa (Stellenbosch region) was very good.
Maybe we should have taken a wine of the Western World to enhance Trans Atlantic reception after all!
This session ended with beautifull view of the Moon and Venus right above us (nice conjunction although some clouds).

Afterwards the session at night was devoted to "Lessons 1-3 of Perseus receiver" at JPRs QTH. We examined, tested and made some test recordings of TA-signals using the antenna farm with no more than about a dozen long bevarages towards the Western Hemisphere. Unfortunatly the conditions were not that good. By the way, once again a projector and a big screen (of about 100 inches) was nice for older dxers (at the picture the attendances are looking at the big projected screen of the Perseus window of a PC).

Exploring the otherwise great Perseus receiver we made a short wish list of Hard-Core-MW-DX:
1)as we always measure the exact frequency down to at least 1 Hz and while we listen usb or lsb we want to see simultaneously the exact carriers using the zoom knob: however that was not possible but we had to switch the mode to AM to see the center frequency and all the carriers around it! So a button to change the window to center frequency also on SSB is almost a must for serious DX - what´s more a list of peak carriers automatically should be fine (like on SpectraVue-software)
2)the timeline has no time stamp, which makes it hard to know where you are, so the label should be a usefull addition here when checking the recorded file
3)the tiny timeline is hard to "hit" using the mouse, maybe a bit thicker timeline will make things easier.
4)also a stamp of the file (automatic putting the day&time to the file´s name) should be very nice.
We liked of course the good sensitivity and all the tools handling the selectivity with Perseus, not forgotting to mention it´s capability to record the whole MW-band to a hard disk!
