Dutch PACC contest my foot handicap prevent me to check and repair the antenna good. The 40m and higher band antenna appeared to be broken just after start. Direct na de start van de contest bleek dat de  3el 10/15   cq  dipool 40/20 antenne niet goed werkte en hoge SWR had op 80 en 160 werkte het nog wel goed. Geen ere plaats dit jaar... 233100 -8 0.3 802 ~ CQ XX9D OL62  Macao cq relative strong my KPA3 sudden broke down... speaking about Murphy law  then tried low power 12W  TX that still worked as long as it lasts 230800 -7 0.4 802 ~ SV1VJ XX9D RR73 230830 -3 0.4 802 ~

144 200W PA WSPR report

Below is the MRF186 VHF 100W PA eBay  2 x parallel coupled excellent quality kit High quality well designed PCB Remarkable it covers 3 VHF bands 6m 4m  and 2m   100W The PCB includes a 3 stage LPF and SWR bridge. This is how all PCB designs for VHF / UHF should be! Lot of tropo DX  at 144.174  last year with just 10 or 8W in FT8 13 dB more ERP  will let me reach the weaker DX running more then QRP.. see building report Jon Joyce GM4JTJ The SWR bridge forward level is about 4V at 100W 144MHz . Measured at board 26.5V 6.5A delivers about 100W  drive 3W 50MHz  1W drive  50W with 28V easy 100W my power supply 27.2V dropped over wiring to 26.5V 2 boards parallel deliver 200W / 26V 12A  at 144MHz   about 4W drive The used balun type  50 to 2 x 50OHm  couplers do not work at 50MHz It is a ferite binoculair core  with a single loop teflon 50Ohm thin coax (1 turn # 3uH ) It must be possible to modify this balun to work for 6 4 and 2 m using 2 turns f.i. Possible I test th
