  Picture shows the U3S -deluxe  with PA build into the U3S housing (deluxe). 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.  The 5 band LPF board the U3S with the 80m LPF0 not visable the small coax cables to the underside of the U3S to place the LPF 0 and 1 2 3 4 5 behind the PA .   This multi mode multi band automatic beacon transmitter is a best seller by QRP LAbs kit by Hans Summers I  build 3 of them, one time they should run as WSPR beacon PU7ZWT in HI11ln  N-E Brasil Some issues : Had to replace the original cheap PC 27MHz kristal with a far more stable TCXO Taitien the blue potmeter PCB More output: I use an eBay 2 trap HF VHF PA having a RD15HVF1 power Mostfet in the final RD15xxx Mitsubishi  power MOS-FET are  used in many rigs like the K3 LPA it can operate from HF to 450 MHz.

28 December // N1MM issues Dutch

                                             10m  160m at the 27  December  now we know this were the last days with exceptional high band propagation f.t.t.b.  N1MM perikelen... In CW contest sinds kort random bevriest het programma , invoer stopt  CW TX stopt , na een aantal seconden word het log veld zwart en stopt ook de CAT verbinding. Dit had ik een paar jaar geleden ook,  oorzaak was toen een aangesloten USB SSD.  Hierdoor bevriest de toetsenbord invoer . Daarna heb ik jaren probleemloos kunnen contesten met N1MM. Echter tijdens de CQWW-CW was het weer raak seconden lang bevriest N1MM De QSO's worden hierdoor verknoeid zeker als je net in een pileup bent. Ik heb tot nu geen oorzaak gevonden het moet wel aan mijn PC  of een  malware programma liggen PA4O had deze problemen niet. Ik verwijder zoveel mogelijk malware en hoop dat de boosdoener daar bij zit. mogelijk is er een verband met Telnet en traag i-net De PC is Win7-64 12GB ram SSD 500G  i7 8 core het is een snelle Laptop

How would it be now  did JT  kill ham radio ? https://www.oldtimersclub.info/PDF/Did%20Joe%20Taylor%20K1JT%20Destroy%20Amateur%20Radio.pdf I think the answer is no, CW is still alive    Surprisingly also DX was possible in CW at peak times The goodies: VK6WX   4D3X (=DU)  E25KAE E29TGW (=HS)  V51YJ ZD7BG L33M LU8MHL LW1D LW5HR XQ3WD CE2ML PT3T  ZF5T KP2M  K1MM  & other FLA here in JO33HG only weak Florida calls heard Remarkable: not a single EA not even EA8  heard  some runs to EU East-EU  and S&P for the few  Asian's in the band.  no SV just one Italian but plenty UR YO LZ LY YL DL OK OM HA    Today Monday morning  in FT8 a lot of EU calls    and VK8AW on the screen..

ARRL160 CW and 80m wspr

ARRL160 CW  was very!  tough going .No remembrance  of such weak signals  during the ARRL160 CW Even the big guns had EME like signals. I stumbled over an similar experience by another contester but that was "on" Facebook or twitter lost it.          Band     QSOs     Pts  Sec  Pt/Q          1.8      57     114   24   2.0        Total      57     114   24   2.0 Low band propagation  season has yet to come..   But 80m propagation is real good over long time now almost daily ZL reports evening or morning longpath over S.A.
