That  beacon should be in FT8 window 70.154.. many USA calls copied XE2OR  1x only here not workable I tried 50.107 classic CW CQ  the  former.. DX part of 6m  was very quiet  during the best of the opening  2 weak USA responding 2018-07-23 13:53 N4ASF 50107.00 CW 519 519 K fm27do 2018-07-23 14:05 K4SN 50107.00 CW 529 559 K el96dc

21 July 6m band open to Thailand

All time new   HS at 50MHz never seen before  Thailand  since QRV  last 3 solar cycles...                                           Psk reporter map very nice but not all dx is shown f.i. XE is not shown Do not go out for dinner if you don't want to miss the rare good openings 2nd time away for dinner while XE2OR was copy'd But later in evening 6m opened again to USA XE2OR in DL98ok !  decoded  working OZ   DL grid heard only one time before over 30 years ago in USB  in solar cycle 23 i think it was later  again heard 205345 -11 0.2 2007 ~ PA0O N0LL RR73 205400 Tx 2426 ~ N0LL PA0O 73 205415 -17 0.1 2201 ~ OZ2PBS XE2OR -18 205432 Tx 2426 ~ XE2OR PA0O JO33 205435 Tx 2426 ~ XE2OR PA0O -17 205500 Tx 2426 ~ XE2OR PA0O -17 205445 -17 0.1 2201 ~ OZ2PBS XE2OR -18 205530 Tx 2426 ~ XE2OR PA0O -17 205600 Tx 2426 ~ XE2OR PA0O -17 205630 Tx 2426 ~ XE2OR PA0O -17

cheap genuine RD15HVF1 do'nt exist

                on eBay or UTsource (above)   its all fake UT source did refund  left is the genuine a bit smaller then the TO220 IRF stamped as RD15HVF1 The original RD15xx types have a small Gate to source C ca 80pF and the source at pin 2 The fake have high gate - C  this one 800-900pF  and its source is pin 3 like all IRF -types The IRF510 has the lowest gate capacity of about 400pF the best of the rest Misubishi's   RD15HVF1 is an  UNIQUE  VHF power FET. With its Source at pin2 = cooling flange,  the only right  place of course No other manufacturers deliver comparable divices. It must be hard to produce. The eBay offered types are all fake cheap IRF5xx imitations in fact fraude. The RD15xxx is relative expensive for a small FET  5-7€  from vendors that will easy take 50$ or more for shipment. Not sold by  Farnell Digi Key Reicheld  and Mouser In RF high power FET segment there is plenty of choice  but   it's crisis in HF VHF  medium power land. The classic
