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 Luis Nice going for 5 watts, but -8 dB with 75 % of the signal recovered , your nearly +30 over the limit .. can you drop the power down by 20 dB ? say 50 mW ?? 73-G, 20:46 477 EA5DOM de G3XKR Op8
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
Luis , Are these qro or qrp ? 73-G, 19:11 477 EA5DOM de G0NBD Op8 Deep Search 1037 mi -36 dB in WALLASEY 1520.0 Hz 19:11 477 EA5DOM de EB5EA Op8 Deep Search 71 mi -34 dB in IM99tn Moncada-Valencia 15
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
Ok,Luis , this was 5 watts ? 19:21 477 EA5DOM de R6LDD Op8 Deep Search 1979 mi -37 dB in NOVOROSSIYSK 1522,2 Hz This 20 dBm ? 19:47 477 EA5DOM de EI8JK Op8 Deep Search 1014 mi -36 dB in Bantry, South
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
Ok Luis , The web-distributed spots have , 1920z for you and sv8cs ? , 19:21 477 EA5DOM de R6LDD Op8 Deep Search 1979 mi -37 dB in NOVOROSSIYSK 1522,2 Hz 19:20 477 SV8CS de EA5DOM Op8 -27 dB F:38% in
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
How odd , may be just at the change over time , but another in from EI8JK and now SV8CS-5 , with -35 dB , the path to EI looks reliable ! skips very sharp these nights , 100 miles and you have droppe
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
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. 73, Tony, EI8JK On 30-Nov-15 08:07, VIGIL
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
Luis That's just 'a silly , -18 dB with G8HUH , I thought you where running QRP, that's close to 20 dB QRO jiji 73-G, From EA5DOM by G8HUH Loc IO81MG Frequency: 0.477 MHz (600m), OPERA, -18dB All OP8
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
