Hi MF Back home ! Antenna is up again and I' transmitting with only 5W from a small PA I will take the opportunity to install the 100W PA in the terrace, as originally planned Txing WSPR and Opera8 e
Hi Graham, MF Good idea. Let's see where is the imit I have just connected the U3 directly to antenna. Have not measured power yet but may be under 500mW I'm not using the 3xBS170 but a mosfet driver
Not bad in Opera Deep Search so far Real decode, as proved with my own monitor decode one minute earlier 19:47 477 EA5DOM de EI8JK Op8 Deep Search 1632 km -36 dB in Bantry, South West Ireland 1520.5
Done 2,33V RMS over 50 ohm load. Should be 0,108w. 20dBm aprox ?? The antenna at Opera QRG is working on the bottom side of the Smith chart at 36 -39j I can measure 2,60V RMS with the antenna connect
That was the last QRO transmission with 5W Graham Txing at 20dBm since 19:22 utc Reports on my monitor from -1 to 0dB So far not monitors in Opera at less than 1000Km 73 de Luis EA5DOM De: owner-rsgb
Well. Looks hard to believe but from my WSPR decodes I changed the power value to 0.05w in the WSPR frame when Txing 20dBm. And the first frame transmitted was 2015-11-29 19:12 EA5DOM 0.475607 +5 0 I
Not exactly Graham The decode on my monitor is at 19:22 not at 19:20 Copy from server spots received at that time 19:22 477 EA5DOM de EA5DOM Op8 7 km -1 dB F:1%_End in Albir 1519,0 Hz 19:21 477 EA5DO
Radical change after 00 utc. Opera spots from SV8CS-5 since then On WSPR the best signal reports came from F1AFJ and G8HUH 2015-11-30 02:24 EA5DOM 0.475610 -14 0 IM98wn 0.05 F1AFJ JN06ht 919 4 2015-1
Thank you Tony That explains the radical propagation change ! :-) Thank you for keeping your monitor working 73 de Luis EA5DOM De: [email protected] [mailto:owner-rsgb_lf_group@black
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
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 73 de Luis EA5DOM De: [email protected] [owner-rsgb_lf_group@bla
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 -37dB from SV8CS-5 at 1819Km 00:34 477 EA5D
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 R
Wow. We have a winner Congratulations Andy ! Fantastic spots -25dB using only 11mW here 2015-12-01 19:36 EA5DOM 0.475610 -25 0 IM98wn 0.01 F1AFJ JN06ht 919 4 2015-12-01 19:24 EA5DOM 0.475610 -25 0 IM
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 A
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
Hi Graham, MF Much worse conditions last night. I even checked the RMS voltage over 50R load to see if the attenuator was not working correctly, but there were the 11mW Only two WSPR spots from Andy
Hi Graham, MF That was just when I went to bed ! -36dB Dynamic decode in Opera. But there was also a G8HUH decode in WSPR with an amazing -17dB !! 2015-12-04 02:12 EA5DOM 0.475609 -17 0 IM98wn 0.01 G
Done Added another 3dB atenuator to the already in use 10dB Power message changed in WSPR and Opera Reports down 1 to 2dB in my monitor. We are really on the "dummy limit" right now PS: The level of
Hi Graham, MF Hard to believe, but true ! :-O Iban EB3FRN and G8HUH spotting me on Opera Deep Search with only 5mW on antenna Specially G8HUH at 1430Km, just one minute after my own spot on monitor d
