The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site.

I just posted poll regarding operations beyond 30m. Please vote based on your interest and ability to operate on a band other than 30m.

During the last week, we've more than doubled the spot rate that we're collecting, and we now have over a hundred regular operators. I think we have enough critical mass to have meaningful operation on one or two (especially if we do day/night).

Here are my personal thoughts:

We're heading into Es season in the northern hemisphere. Most seem to think of this as germane to 10m and above, but it affects lower frequencies as well.

I have now started WSPRing on SIX

DIAL 50.293,000
Tx: 50.294,535

This, of cause, only have value if a critical mass of active stations is reached, so please join in if you are at all interested in VHF propagation.

Currently running 32dBm to an omnidirectional, vertically polarized, antenna.

I plan to run this activity throughout the day and evening time until the end of summer ES (unless, of cause, if it's a complete bust with no activity) When not otherwise active on the band.

This seems a handy place to Notify and Remind everyone about my 5 unit Multimode Visual + WSPR MEPT.

Reports to the WSPR Spots or Screen Captures are always welcome, whilst it does involve a shift of Dial Frequency to 10.1386 in order to receive the Beacon, during this time stations can still RX and TX in the 10.140100 to 10.140200 Range.

MEPT Frequency 10.140073MHz.
Power 40mW.
Antenna 40m 1/2 Wave Doublet + ATU - OR 6m Vertical + ATU - OR 0.9m Hairspray Vertical. (Variable)

I heard from Bonnie KQ6XA of ALE/HFLINK, who pointed out that my proposed new frequencies on 15m and 12m overlapped primary ALE channels by about 100Hz, so I'm updating the matrix below and on the sked page to move them down by 1 KHz.

We have about 100 stations operating WSPR regularly, almost all on 30m
most of the time (9,300 spots there today). We have had small nomadic
groups try out different bands, but I think the next step should be to
decide what bands we would like to get a critical mass of operation
on; having only a handful of stations on a band doesn't tell us nearly
as much. On the other hand, if we spread ourselves out over 9 HF
bands, we wouldn't have critical mass anywhere.

My initial thought was to try to promote a group on 10m during the day

2008-04-19 update: After no negative and several positive feedbacks, I'm including the new suggested frequencies I sent out and posted a couple of days ago, modified by 1KHz to not overlap the ALE channels.

Also, please note that many JT65A operators also run WSPR while on JT65A calling frequencies, particularly 7.076 and 14.076.

The 6m frequency is not settled yet; several are using 50.293 as a starting point.

160m 1.808.6 1.810.1
80m 3.592.6 3.594.1

This is a community blog, to which registered users have the ability to contribute (under "create content" -> "blog entry". This can serve for more long-term community content than forum topics. Enjoy!

We clearly have a critical mass of WSPR operation on 30m with over
25,000 spots on 30m alone in the last two days. As we being to think
about more systematic operation on bands other than 30m, we should
really standardize on where to operate. This message is long, but I
don't want anyone to think I'm arbitrarily suggesting changing some
frequencies on a whim.

To net it out, this is a proposal to:

This is the new home page for the WSPR community. You can still easily get to the Sked/Chat page and the database page via the links on the left, but here we can also post articles, reference information, have forum discussions, etc. If you are an amateur radio operator using WSPR or interested in it, please register an account for yourself using your call sign as the login name.

Eventually, the Sked and Database features of this site will all be integrated under this framework.
