WSPRers,

Keep in mind that we have a couple of active stations now who's radios are highly accurate and stable being locked to GPS or Rubidium reference.

Stations Im aware of so far are -

Iain VK5ZD - 144.490540

Jim VK3ZYC - 144.490500 ? (needs to be verified)

David VK5KK (?not sure, but Davids sig is very stable) - 144.490501


So if u find you can hear/decode signal from a Ref Locked station, you can verify your rigs accuracy and adjust if required.

I've listed the stations TX freq above. So if you are able to get a signal, for example, from Iain VK5ZD, we know he's station is set to TX 144.490540. So when your program decodes VK5ZD, you should see his decode reported at 144.490540 in the program.
If its not then you may need to tune your RADIO dial freq up or down accordingly to correct this. This will then get your radio tuned up as accurately as possible.
So for example if you did decode VK5ZD at 144.490511 for example. You would need to tune your rig down 29 Hz to get it on exactly the right freq to the Hz. After this VK5ZD should decode close to 144.490540 ... depending upon how drifty ur rig is with temperature. You may need to re-check and adjust now and then if it does drift over time of course.

If anyone else is on, or sets up 2m WSPR with ref locked radio please advise us in this thread. Let us know what you have set the programs TX freq to be so we know where we should have you decoding at.
Thanks

Any other updates for 2m WSPR stations who are now ref locked ?

Here is the current list that I am aware of and what freq they occupy -

Iain VK5ZD - 144.490540
Jim VK3ZYC - 144.490550
David VK5KK - 144.490525
Andy VK5LA - 144.490515
Keith VK5AKM - 144.490470

Hi,

VK3ZYC Normal frequency 144.490550 Mhz.

Jim.

Thanks Jim, Ive gone back and edited my post with your info.

A new addition to the list, Dean VK3NFI.

G'day Leigh,

Chuck me on the list as well, TX frequency for 2m will be 144.490570.

Cheers

My 2m station is now locked to a GPSDO

TX frequency is 144.490460Mhz

Derek,

This is great news, well done

It looks like Dean VK3NFI is on 144.490450 already, could you perhaps go for 144.490460 ? or maybe 440 ?

Changed to 144.490460Mhz

Righto Derek, will do a list update.

Here is the current list and what freq they are set to TX on -

Keith VK5AKM - 144.490470
Derek VK6DZ - 144.490.460
Dean VK3NFI - 144.490450

Thanks to some great input and encouragement from David VK3HZ and Andy VK5LA and others, I've now got my IC910 GPS locked.

I've been thinking that its probably a good idea if GPS reference or OCXO hi stab stations clear out the middle of the 2m WSPR bandpass. Probably a good idea to make that area clearer for non locked stations that are probably better of being in the middle.
I've moved mine out to 144.490560. So people may notice a change to where I am showing up.
I've also moved stations who aren't regulars out of the main list so the freq's they were on may be taken up by others.

Here is the current list and what freq they are set to TX on -

Jayson VK1JA - 144.490570 (GPS)
Leigh VK2KRR - 144.490560 (GPS)
Andy VK5LA - 144.490515 (Rubidium)
Keith VK5AKM - 144.490500 (OCXO I think?)
Derek VK6DZ - 144.490.460 (GPS)
Dean VK3NFI - 144.490450 (GPS)
Phil VK5AKK - 144.490??? (OCXO I think?)

Stations known to have GPS locked rigs but not often on WSPR-

Jim VK3ZYC
Iain VK5ZD
David VK5KK

Has a similar database/thread been setup for those primarily on 6M?
e.g.: "6M WSPR Ref Locked Stations"
Danny VK6DVR PH12cf Broome

Hi Danny,

No I dont think there is a thread for locked 6m stations. Primarily because in most cases its not really required on 6m, rigs mostly seem stable on 6m.

I dont know who has a GPS locked 6m station. Some of the JA stations seem to but dont know of any VKs. THough I could be wrong. I guess someone with a TS2000 could have a locked device.

Hello,
I have moved to using my IC-910 for WSPR now that I have the Omni-antennas in the air http://www.parelectronics.com/omnis.php

My decoded signal should show up as: 144.490460 in WSPR at your end.

Above 500 Hz segment was getting a little crowded so have slipped down there until further notice. If you notice me drifting, its either I am on the old rig (IC-275) or the antenna has been pulled of the GPS receiver again

Regards,
Peter, vk5pj

Hi Peter,
Seems Derek was on 460, but looking at the map now, seems he may have moved to 485, so I might amend the list accordingly.

Here is the current list and what freq they are set to TX on -

Jayson VK1JA - 144.490570 (GPS)
Leigh VK2KRR - 144.490560 (GPS)
Andy VK5LA - 144.490515 (Rubidium)
Keith VK5AKM - 144.490500 (OCXO I think?)
Derek VK6DZ - 144.490.485 (GPS)
Peter VK5PJ - 144.490.460 (GPS)
Dean VK3NFI - 144.490450 (GPS)
Phil VK5AKK - 144.490??? (OCXO I think?)

An update with Jeff VK5GF, Wayne VK2XN, Scott VK4CZ (not sure where u are Scott? 470 ?)

Its probably a good idea to try keep +- 10 Hz of 500 vacant for stations who are not locked, so they can try get in the middle of the bandpass. But in some situations like VK2XN, being in a more unique location, being on 500 should be OK.

As more stations come on board with locking, we can have some discussion regarding if there is any better placement for some stations. But currently I think all seems OK.

Here is the current list and what freq they are set to TX on -

Jayson VK1JA - 144.490570 (GPS)
Leigh VK2KRR - 144.490560 (GPS)
Jeff VK5GF - 144.490530 (GPS)
Andy VK5LA - 144.490515 (Rubidium)
Keith VK5AKM - 144.490500 (OCXO I think?)
Wayne VK2XN - 144.490500 (GPS)
Derek VK6DZ - 144.490.485 (GPS)
Peter VK5PJ - 144.490.460 (GPS)
Dean VK3NFI - 144.490450 (GPS)
Phil VK5AKK - 144.490??? (OCXO I think?)
Scott VK4CZ - 144.490??? (GPS)

If ok i'll keep to 144.490470MHz where I ran over the w/end. At this stage I'll only be 'active' on w/ends after other activities cease.
