Trans Atlantic. beacon copy by CT1HZE 70005.0 WG2XPN/B 2016Z 23 519 3xEs!
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 13:53N4ASF50107.00CW519519Kfm27do 2018-07-23 14:05K4SN50107.00CW529559Kel96dc
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 bipolar RF me…
This afternoon 14 July i saw this remarkable spot 151700 -9 0.0 2100 ~ XE2JS SP3E JO72 XE2JS is in DL68 !
but we had to go out for dinner
6m DX typical happens around dinner time
I thought to be smart and let the rig at 50313 with Teamviewer for remote control
But the always working remote Teamviewer access now was broken
Typical internet/ network it seems to refuse to work when it is needed
strong reports from DL but here zero XE2JS
at first no DX copied but later some USA in Golf area came in my QTH
