I'm on 477 opera as well as 474.2 WSPR
I shall leave it monitoring both all night

Still  big signals  Luis !

We know from the Vampire tests , what should happen, but , there is no accurate way of telling who is actually running Rx on 477 now, since the psk-map changed the housekeeping routines ...

Im Rx 477 at the moment , only see your local decode's at the moment

No more DX last night at 11mW

One spot from F5WK and many more from Andy F1AFJ

Maxi, EA5CV got a few at -28dB and being just 60Km away but with a sub optimal Rx
No other EA station got copy

No Opera spots. Monitors were too far, probably

There were few TA spots across north atlantic. So, conditions were not bad Will keep Txing at this power level untill finishing the PA install at terrace

Wellcome to the 11mW challenge, Clemens :-)

F5WK joined the party with just one spot but breaking the distance mark to 1192km

2015-12-01 20:24 EA5DOM 0.475608 -28 0 IM98wn 0.01 F5WK IN99ef 1192 355

Andy has 8 spots so far. And one as good as -20dB !!

2015-12-01 21:36 EA5DOM 0.475610 -20 0 IM98wn 0.01 F1AFJ JN06ht 919 4

You are at 1515Km. A real edge for such a weak signal ??

Hello Luis,

I wonder if there is al least 1mW ERP out ! Still a lot of
room for Opera Deep Search spots

Any other taker ?

I'll give it a try tonight.
RX and WSPR are running now.
I know I can compete with DH5RAE and DJ0ABR regarding WSPR spots (RX-wise).
I'm also quite out in the sticks...

OK Graham, there we are ! ;-)

0,742V RMS over 50Ohm. That's 11mW

Can see 1dB down in my WSPR monitor at 7Km. Reports from EA5CV
which were about -25dB are nill now

Really challenging for me and for RX stations. Probably will
get some spots from EA5CV and EA2HB during
the night, but for >1000Km paths it will be very hard,
depending on propagation conditions and noise floor

WSPR power message set to 10dBm and Opera info changed to 0,01w

Make your bet ! ;-)

Getting there  Luis !

Your 6 dB  in hand  with  G3XKR ,   may be more with G8HUH ,

Go for the  big  1-0    TEN    mW , the  stats are not  good ,
you  need  to  get a  peak  aligned with the  qsb , but  with
 8% fade , but, signal must be  holding  up ...

Hi MF

Yet some remarkable results with 51mW. May be propagation
conditions lowered extra dBs

Anyway, in Opera got a -30dB decode from G3XKR and Deep Search

Should I get down another 3dB to 25mW and still spotted by F5WK ?? :-O

Let's go step by step

3db down now: 1,60V RMS 51mW

Same signals on my monitor and some drop on F5WK and EA5CV reports

Hi Graham, MF

Yes. The efficiency of this antenna setup is really outstanding  :-O
I can clearly see the signal on my monitor waterfall at 7Km
when injecting -33dBm

Just at sunset between EA and DL I got two WSPR decodes from
DH5RAE and DJ0ABR

 0      IM98wn          0.05    EA5CV           IM98ol

 1576           39

I have the 3dB atenuator ready to be installed. Will do it
when I get home in a couple of hours
and will change the WSPR tx power indicator and Opera info to
notice the change

Luis, I switched my radio off last night at about 23:30 utc.
I will leave it running opera all night tonight if you want to
try different power levels again.
