Re: LF: Re: Amazing night in LF. South Dakota at 7660Km in WSPR-2

Hi Markus, LF

I agree with you about WSPR-15. And keep a decoder always running in LF. As it uses the same dial frequency as WSPR-2 is very easy to run both decoders over the same received (note for those still reluctant)

Last night the LF PA was dismantled to install it today on top terrace. So I tried with just the bare U3 to antenna, which may be well under 500mW. And you managed to copy me once

I must say it is not the first time. This worked before. Even before winter solstice. And clearly remarks the performance of wspr-15 mode

Monitoring stations need signals. Both in quantity and quantity. They like to compare performance of their receivers and antennas. And that can be nicely done combining frequent wspr-2 and a couple of wspr-15 per hour

Unfortunately more than two cents in electricity bill but it worths ;-)

Hi Luis,

I've been  monitoring  WSPR-15 here during many nights, and whenever someone in DX came up the results were usually quite satisfying. DL0AO normally observes both variants continuously (although the old wspr-x r3058 software occasionally terminates itself quietly and needs to be restarted).

Personally I do have a definite preference for wspr-15 over -2, because it can go much further, and also because it won't clutter up the web with such a flood of reports - better choose Quality over Quantity ;-) When you see -29 dB in -15 you anyway know you'd have made it in -2 as well, but at -38 dB it doesn't work the other way round. In case you want to monitor fast propagation changes in near-real-time, a simple straight carrier would be the most efficient tool (just my 2 cents Sunday opinion).

All the best,
Markus (DF6NM)

The only way to convince SWLs to run WSPR-15 instances is to put a signal on air and compare results
