Hi Stefan, MF That would be great ! I have seen the first EA7 (Andalucia - South Spain) QRV on WSPR MF last night And have to find any interested in Canary Islands (EA8) I'm going to boost to 100W ne
Hi MF One more test here to check if there is any difference in SNR when using WSPR-2 and WSPR-15 for a short path I set my U3 at QRPP. Low enought to get about -9dB at WSPR-2 at my remote monitor 7K
Amazing signals and amazing distances Edgar :-O Please keep up the good job on keeping us updated with this 73 de Luis EA5DOM De: [email protected] [mailto:owner-rsgb_lf_group@blacks
Hi Stefan, MF Good to know you have managed to get CT1JTQ interested in the low bands :-) I keep Tx every night on MF WSPR-2 + Opera8 + QRSS at 476.178KHz every 30 minutes But no decode at CT1JTQ so
Hi MF I'm back again with is topic While making some calculations for the <crazy> vertical I recalled Stefan's comment "If C is 55 pF and your losses are 50 Ohm and the power is 50 W, you will have 6
Hi Stefan Thank you for your comments on this <crazy> topic If you remove the counterpoise wire from the PL connector, the screen is floating so there can be no HV problems. Or do i missunderstand so
Hi Stefan Can see CT1JTQ QRV on WSPR map but he doesn't receive any station Which is his Rx setup ? 73 de Luis EA5DOM --Mensaje original-- De: [email protected] [mailto:owner-rsgb_lf
Hi Stefan Yes. I can completely remove the cable for the motor at the antenna. It uses a connector But then I wouldn't be able to retract it quickly (or remotely) in case of storm I would have to acc
Hi Joe Not really readable but bet it is your signal. Received all night long here on the mediterranean coast IM98WX https://dl.dropboxusercontent.com/u/7162072/Docs/476KHz%20Grabber0008.jpg Need som
Hi MF Hope to copy you on OP8 Joe I'm also Txing. I have increased power to about 100w into the horizontal loop Thanks to Fausto, IK4NMF for providing the PA So far this has proved to add some dBs to
Thank you for the spreadsheet Andy I have set the parameters of my loop. As I know the total lenght and capacitor used to tune it have adjusted diameter to a theoretical circular loop. Don't know the
Fantastic. Very close to being there Just miss the smell of old iron and copper :-) The site is quite complex. I miss some schematic or coarse description of the different blocks ans were are located
Hi Mike, MF From my records last night, DK7FC was transmiting in 06-16-26-36 ... periods, but not at 23:04 The locator shown in your decode is also wrong The closest frame to the time you decoded was
You catched me Graham ! ;-) Running the horizontal loop again. Better matching to the PA than before, but only 8W now I have continued Txing WSPR and Opera8 during daylight hours. Nothing on WSPR-2 a
Hi Graham The answer is ... QRO :) I'm running the 100w PA made by Fausto IK4NMF. Not big signal increase in local (7km) decodes but clear difference at 300Km as seen by EB3FRN After improving loop m
Even with the loop we are on the way ;-) 2015-09-29 22:00 EA5DOM 0.475611 -27 0 IM98wn 0.002 DK7FC/P JN49ik 1398 27 73 de Luis EA5DOM De: [email protected] [owner-rsgb_lf_group@black
Hi MF Probably not 2mW ERP Stefan ;-) Have to reconfigure my U3 but really don't know which ERP I'm getting right now The PA outputs 60V RMS under 50Ohm load, but the loop is not an ideal load and I
Hi Stefan, MF I have been calculating the loop area with the help of Google Earth. Not a regular shape but counting on the known perimeter and measures it can be estimated as 224 m2 I detect the RF c
Reaching here in Deep Search Mal -35 and -36dB and you are Txing on 1520Hz Keep trying and may be we can get a decode over Deep Search level ;-) 73 de Luis EA5DOM ____________________________________
