FT8 160m Japan pile up in a busy CQWW PHONE top band !

Every HAM knows that the CQWW Phone weekend in topband is not exactly a pleasure for CW DX  friends.. Hard to believe but  this is no obstacle for  FT8 In a crowded CQWW SSB 160m band I was  having a pile up of Japanese stations  running CQ barefoot Receive 1908kHz dial   Transmit 1840kHz dial JA with the typical deep QSB  but  most callers in the log  19 Japanese HAMS thanks for calling also seen HL3GOB and another HL forgot the callsign  HL3GOB  was worked 6M in summer real magic    !

23cm Transverter

My 23cm dish plus transverter  is now down  for revision                                          measured by ham 0.15 db NF!  it has a band filter                                                               this XVTR box is at the dish the feeder tube enters top left to                                                                  connect the relay as direct as possible                                                           The new SKY67151 LNA just fits in next to the relay replacing the SPF5189z                                                                         the SWR d-coupler say 1:1  with this combination                                          these Chinese eBay connectors  can not be used for 23cm 1300MHz                                     it will result in high SWR and lower output and possible instability My transverter is a modified DB6NT  + 30W PA And SPF5189z preamp 0.73db nf this worked very well F.i.  in oktober  test OM3KII w

Japan 160m FT8 , VP6D at topband

In Japan digimode is allowed 1907.5  to 1912.5 kHz only FUNK FA 11/18 1087 ( posible in future i am thinking of writing in German language since the Brexit  why should we use Englisch ?) JA TX  USB dial  1909kHz or 1907kHz   rx dial 1840kHz EU send 1840kHz  RX  dial 1907 or 1909kHz where ever signals are seen. Tonight i tried with succes for the first time with several JA stations 2-way FT8  heard HL  HL3GOB dial 1907 must say it is some time ago i have seen JA in CW at 160m JA CW is only in the JA -window 1810 to 1825kHz  and that part is mostly occupied for us In contest the only chance is calling S&P normaly and only the big guns can be worked But in FT8 it is easy 100W! i just set my K3 VFO A to   dial 1907kHz   mode DATA A and VFO B to the usual 1840kHz WSJT-x  setup   radio split operation must be none but the K3 must be set to split  TX 1840 rx 1907 kHz thats all  btw  this morning VP6D  was on topband weak but some QSB   1826.5 up many EU heard call
