Those GPS 1pps problems. (Some bystander thoughts)
Yesterday I thought I'd try to do a bit of research regarding the
GPS modules used by kit owners.
Now I'm not sure if I've got all the model numbers correct but
from what I've seen so far, all the

Re: v2.02k - Twice the fun, WSPR and QRSS together!
This is the upgrade I'm most excited about!
Once the Martello Tower Group have received their 2.02k version, we will be installing it into G0PKT and running both WSPR and QRSS on 30m and setting up a

Re: v2.02 released
Seconded ! The improvements are OUTSTANDING.
Hans has done absolutely brilliant work on this version, and it stands
head and shoulder above anything I've seen so far.
I've already ordered my bunch

Re: v2.02 released
Hi All
I recommend v2.02a be rapidly installed in all v2.01 U2's.
It really is good. The improvements in spectral purity are outstanding and some of the operating convenience improvements well worth

Re: v2.02k - Twice the fun, WSPR and QRSS together!
Hi Hans
That's great, exactly what my PIC DDS MEPT does, shown on Knights Frequency Table as 8minutes QRSS, 2miinutes to commune with Satan. I knew you would manage to do something with those few

Ultimate2 kit status

An update on where I am with the next batch of U2 kits, which I had hoped
to have ready near the start of June, but clearly that was over-optimistic.
Firstly the PCB manufacturer claims a 1 week

v2.02k - Twice the fun, WSPR and QRSS together!
Good morning all,
This is all the fault of Keith Maton G6NHU, who asked for a special
version. Then we thought others might like it too. So that became v2.02k.
It is based on v2.02 but the

Re: Argo - Display Actual Radio Frequency
I don't think you should assume your receiver calibration is absolutely correct or that the sound card frequency display is spot on.
This is what I do to set up a QRSS transmitter. I set Argo to

Re: Argo - Display Actual Radio Frequency
Argo v1 build 143 :
I set the two left-hand boxes to 1000 and the right-hand to 10138700. This allows QRSS and WSPR to run simultaneously.
Obviously you need a filter bandwidth of at least 1.3 kHz

Re: Argo - Display Actual Radio Frequency
I set my receiver to 10.139000 USB
Also set Argo to 10139000 Setup/calibration
This takes care of the offset and you get a proper read out in the LHS
Hope that helps

Argo - Display Actual Radio Frequency
Hi Gang
Just built my 3rd QRSS beacon - this time it's the Hans Arduino shield. Mighty fine piece of kit too!
I've managed to completely confuse myself with the setup of Argo and hence the frequency

U2 Spotted on 7MHz
Not the first time I have Spotted Andy G0FTD's U2 on 40m but the mid screen ident was a spot of luck..
You may be able to spot yourself on my Grabber.

Re: WSPR TX Time Charts
I am watching this one with interest too.
I have a U2 which I initially used with no GPS.
I calibrated the clock frequency correctly and left the U2 on WSPR
witn NO problems. After a day the U2 was
