4m 70.151MHz wspr activity

At present G6HSM is the only? regular wspr transmitting station at 70.151 tx schedule xx:x6
Occasional i am also at 70.151MHz tx and rx.
70.151 seems to be the agreed wspr dial frequency and FT8 = 70.154 this fit's in the DL 4m band

I was uncertain about receiving performance since the last DX event with the 2 Kazakhstan ham
i saw "everyone" working hearing UN7MBH and UN3M
here only 2 very weak decodes my antenna seems broken??
124700 -21 0.4 1105 ~ M0UKR UN7MBH R-23
130300 -15 0.2 1654 ~ CQ UN3M LO61 CQ Zone 17
Good to have a beacon with a weak stable signal within reasonable distance.
So i compared with an other 4m HAM  receiving G6HSM and concluded nothing wrong here technical
Just i am in JO33HG north and ES tends to be staying more south...

Saved a session G6HSM that failed to decode however the trace looked fine to me to decode.
Checked save all, don't forget to uncheck it.
Every receive wav file takes 352k this one took 2813 k bytes. 8x more if deep decoding is checked.

If you run 24x7 wspr like me the HD can be stuffed with thousands of files.

I did reload/re-decode that wav session it did not decode.
Then i changed the decoding option from deep to normal and fast.Still no decoding
Changed it back to deep and then it decoded 3 times in a row that is strange or not ?

G6HSM DX  is 427km
Weak trace with some drift on the edge of decoding
Receiving with homemade XVTR ,antenna 5el 22m a.g. preamp SPF4350z MMIC 0.8 n.f.
It does decode only about 50% of the transmissions
Stange is that weak traces seem to decode better then stronger one's ?

the last 3 decode lines are from reading the wav file

since i have done this test where i only changed the decode setting to fast normal and back to deep where was.
Coincidence or not In a row all tx sessions are decoded !
2106 2116 2126 2136 2146 2156 ..
Something is changed ? possible it was not really set to deep internal??

last week some more results but only very few active 4m WSPR
