WSPR bogus decodes 2019 are stil present in 2021 LQ0HGF 14MDA

last 2 weeks check on LQ0HGF and 14MDA possible there are more "calls" like this those implausible decodes are multiple decoded over a long period of time 2018 until now their locations always end in the middle of nowhere No stratospheric balloons since the locator is not changing my guess, this is a software issue TimestampCallMHzSNRDriftGridPwrReporterRGridkmazMode# Spots 2021-02-04 20:06 LQ0HGF 5.288599 -8 0 RP22 200 EA8BFK IL38bo 9887 359 2 1 2021-02-07 07:44 LQ0HGF 5.288756 -19 0 RP22 200 DK8FT JN58oe 7492 341 2 1 2021-02-03 15:32 LQ0HGF 0.475739 -21 0 RP22 200 DL0AO JN59vk 7347 341 2 40 2021-02-07 19:16 LQ0HGF 7.040099 -17 0 RP22 200 G8LCO IO91vu 7235 350 2 1 2021-02-08 12:08 LQ0HGF 18.106201 -18 0 RP22 200 DM3FML JO60ux 7148 340 2 1 2021-02-17 06:20 LQ0HGF 5.288589 -26 0 RP22 200 DL0HT JO43jb 6999 344 2 1 2021-02-03 18:54 LQ0HGF 14.097021 -12 0 RP22 200 SP7WT JO91 6996 337 2 36

PACC contest 2021

Our National PACC HF Contest weekend, while the halve nation was out on the ice. Aa canal in city Groningen. seen from my former QTH where i was active as PA0OOS from 1972 in those day's we had cold winters but no-one was ice skating there 40m linear loaded/ foldback dipole PACC our national HF contest 24 hours February 13/14 is history. After some doubts i choose the A1 section CW 100W power Rather cold even in the shack at night i had to use an electric heather .. During the quiet periods thoughts came up saying it makes no sense energy wise , switch off the heather and on the PA.. but i did not. Again top activity in CW many long time PACC friends seen on the bands thanks for giving out points. just a serial number and the obligatory 599 will do. A pity that no easy 28 MHz local DL OZ ON G could be logged that could have made the difference between first or second position. Also zero SA CW activity no PY LU in the log, propagation was good enough.

CQ160CW CW alive and kicking

I choose to enter the low power 100W max. contest section. K3 i-L 25m vertical and rx Beverages E/W Since in our ADSL2+ network a "notch" is set by the KPN network provider,what a relieve! finally. TX-ing 1.8MHz is without interfering our network TV. Did you know that ADSL2+ is using 1-2 MHz base band ? The KPN helpdesk man and woman do not know this. Friendly people but they are schooled in "communication" that's how they call it in the University and schools it has nothing to do with technical communication but it is a sort of training to build a pleasant buffer between the public and authorities in general, many good job's to get in this field ! Thanks to a real KPN technician the ADSL2+ carriers within 1.8 - 2.0 are switched off, called a notch. This is the only way to get rit of 1.8MHz RFI in the network all other methodes failed.

ISS MMSSTV picture

Strong passage of ISS Receiving results at 472.4 kHz are very poor this year no USA decodes seen so guess the receiving antenne has a problem. The 40m rotating dipole "lineair loading" 14m shorted works reasonable. Tuned in band the top wire capacitieve loads are very critical in length. 10cm / 100kHz . I now use special very flexible wire and a small nut end weight to keep the wires 120cm lenght stretched. Last night at 7.093 the NL Nasiballen round VE1CHW slightly better copy on the dipole about 1 s-unit in favor of the dipole at 22m a.g. against the GP with base at 1m above ground. The GP is a much easier antenne to set up.

Powered by 12V 1.5A max 1 UA7805 for the U3S 5V, A IRF9510 P-channel + NPN BC557 to make TX 12V switched by the U3S "key" and an connected UA7805 for TX5V.
