I finally have my LF receiving setup active again. K2ORS is very audible 24 hours a day. I spotted WH2XND (on 138.000 WSPR) 99 times the first night back and 113 times the second night, so things see
I will be making some overnight transmissions on the 136kHz band, using Opera32 in the next few days if you would like to monitor. It is possible to run Opera and WSPR receivers at the same time. I w
Hello Mike, Looking forward to your first WSPR on LF. I'm watching for you in WSPR-2 and WSPR-15. 15 is also possible with the U3, right? 73, Stefan Am 24.10.2017 11:58, schrieb Mike Dennison: I will
I'm also monitoring WSPR-2 and Opera32 in LF. Was in WSPR-15 too, but finally abandoned that mode. There is less activity than in EbNaut ;-) Very low activity in WSPR-2 too. Just Chris, 2E0ILY. Last
Hi all, N1BUG was my first TA in previous MF session. Now taking my first steps on LF would be a pleasure to repeat. Pse Paul, this saturday again ;-) 73! Alberto-EA4GHB 2017-10-25 18:31 GMT+02:00 VI
Yes, WSPR-15 is possible with the U3. I may have to add a fan to the PA, though, as I have never run a 15 minute continuous transmission at full power before. The U3 is an amazing and cheap piece of
I was very happy to provide your first TA report on MF in the previous season, Alberto. I hope we can do it on LF this time! I am continuing to monitor LF WSPR every night. So far I am only hearing t
I wish it were possible to have more WSPR-15 activity on LF. It seems like a very promising mode and would be much more interesting to me than Op32. Unfortunately for many of us the old WSPR-X softwa
Hello Paul, I am surprised you have had issues with WSPR-X and WSPR15 I often forget I have it running in tandem with WSPR2 on WSJT-X and it is still sound and solid after a few days. PC is Windows 7
Paul 61 material has the best Q of any of the ferrite materials (that I'm aware of) at LF/MF. Can't say whether or not the change to a different coil would be appropriate in that circuit. Jay W1VD WD
Thanks Jay. I am far from knowledgeable about these materials but that agrees with measured performance of several receive bandpass filters I built for LF/MF last winter. I tried several different fe
Hello Chris, It seems WSPR-X is "conditionally stable". We had a fair bit of discussion about it on this side of the pond last winter. It works for some, but for others it doesn't. For me it stops do
Paul, Conditions were much better last week. We are currently in a coronal hole flow which has depressed the northerly LF paths. Dst numbers are around -70, another indicator. DCF39 was way down last
Agreed John - last week dcf39 was up to S6 over the North Pole - and this morning I see no trace at dot60 slow on Argo "...things can only get better......" ps my 2200m tx has been on and not one dec
Paul, However I have no idea how that would compare to the powdered iron T50-2 normally used in this circuit. <<< I have sucessfully used T50-1 and T68-1 powdered iron toroids. The optimum frequency
Paul 61 material ferrite will give higher Q than -2 powdered iron at LF/MF. Nothing wrong with -2 powdered iron ... it's just 61 material ferrite offers superb Q. I wouldn't recommend any of the lowe

Hello Domenico, Very interesting and a good work, my compliments! I often had the wish to have more options for the WSPR uploads. For example i'm running 2 instances on MF from the two loops on the t
