Flex after v2 software upgrade has decided to recalibrate around 400hz up in tx freq..Ie rx 7.162.000 TX 7162.400....Was perfect prior to upgrade so I can only guess that there is a calibration technique, tried the 15mhz calibration, no change, but its 2am in Australia, propogation is pretty terrible, any suggestions Cheers Brenton VK3CM Tangambalanga North East Victoria Australia

Select enter another frequency like 10 MHz or any WWV or other frequency standard. Hit calibrate.

I highly recommend running the calibration after every software update. Also, try to run it on the highest frequency you can receive. A calibration at 10MHz is good but one at 15MHz is better.

Hi Ria,

Do you ever have a problem with SSDR forgetting the offset?  Seems that every time I go look there, it's at 0...and it's not from updating the software.

HI Ria
tried recalibrate on every time signal known to man, consistently 100hz high on tx, so I am just dropping my 7105 to 7.104.9 and everyone on the net is happy. So, my beautiful fixer of all things Mrs Ria, Im missing something simple, checked xit rit etc, that would have been an easy fix, but its happening on both the computer with dual screens etc and the Maestro and until my one day old ipad's software expired after paying $79.99 yesterday, it was doing exactly the same thing.  Not frustrated by any of this, using it more as a learning curve as we are busy working on a project in the middle east and we have 17 sites in a particular country ready to go and my engineers are just laughing at me as they get the hard work to do, and I refuse to let them look at this, two of them were over from Israel a few days ago staying at my snow fields property, actually it was working perfectly then, but they are in Singapore with team members right now and I suspect over a beer saying, do you know our Aussie guy has got himself 100hz off and is still trying to work it out...Hopefully they dont read forums haha. They are just too smart, my spidey sense says they know Im in trouble.   Small issue thank goodness...

This is a game of pride versus anything, and these two are smart engineers, both ex Motorola GSM designers, extremely smart but I have to beat them on this one, otherwise the next beer is on me....I could tell you some stories of singapore parties with these two that actually thinking about it, my secret is safe, I have video evidence on there attempt to dance with 2 russian women in a Singaporean club, wasnt pretty.  And I warned them, they were not the girls were not there to make friends for fun.  They came back to me shocked when $500USD was mentioned, haha, I learnt a long time ago, 45 countries ive travelled through, be polite, but honour the woman you love back at home, you will also live a lot longer. One of the international companies i have been employed by and affiliated with for most my life made us all do a 2 day course on all the things that wont kill you but will haunt your life forever.  Some of our staff slept through it, me, I couldn't believe the risk some men are taking, let aone the greater issue of respect for wives back home.   To be fair, my two Israeli buddies,  they were not looking to do anything but dance however I still have it on video, you can see when the the russian girls hit them up, its priceless.  When they got hit up for $500USD, their faces just went, bye!!!!!!....

OK Ria, gossip aside, save my butt here, I can camouflage my error with my rit/xit 100hz trick on the remote modules etc, but my 6700 has somehing that is not quite in tune with the other 1000's of others out there, and I probably caused it.  Any of your thoughts appreciated, and the rest of the group of course, unless your one of two israeli engineers, remember, I have the video...haha

Saved by the 5 mhz time signal on 5 mhz........Problem solved........sets at offset as -3 as an indicator.
Also have N1MM pan adaptor working tonight, unreal tool, still a few questions, but at 2am,tie to sleep....Thanks fellow Flex owners, sorry to bother you on this one, we worked it out 30 seconds after we listed the question.

ahhhhhhhhhh ria, your a gem, we only just beat you but your answer was 100% correct, as per usual, I need a hotline to you.....cheers from australia, and off for some well earned sleep, spent half the night on technical problems with Israelis, great mates of mine but boy, it took us hours sorting out some issues.  I told them at 1am I was going to bed, But the Flex kept me up playing.
Did some great tests with Version 2 today with some encryption software, worked beautifully....
Also, have you played with N1MM 's software, just started, looks like a full pack of options.
Thats it Ria, sleep, cya Brenton VK3CM

HI Ria, my wife says guest room prepared and always welcome....OK, so back to technical fun, I was spot on with my 5 mhz signal last night, many thanks, but being in  engineering, its hard not to play, so I hit wwv, set 15 mhz, back to 200khz high doh!!!!!! Why do Australian boffins like me have to play, answer, too much time on our hands haha.  Two of our visiting engineers just left back to their country of origin and Im thankful that they didnt see me "playing" as all test went well for the sites in the country Matt is aware of.  OK, back to normality, do I just go back and do my 5mhz tune tonight, or am I doing something wrong with the 15mhz signal.  It automatically goes to USB that sounds correct, redult is 0 offset, could my N1MM screen above be playing with its normally alone process.  I can see on the N1MM software the TX cal moving back and forth.  Might just shut down n1mm as 15 mhz with a 16 element optibeam pointed at it is 10db over 9 so thats great, and should provide excellent referencing.  And Ria, do you like the snow, we have lots of it right now....Look up Tangambalanga, we are at 102 hogan lane, 5 acres slowly being covered in Antennas but we are so close to Falls Creek Snowfields, we love taking guests up to the snow, we tell them we own it all of course, havent had one believer yet....One day we will strike someone gullible enough haha....Anyways, always welcome, plenty of room here,my son is a ham, I think I said this before, and my wife(to be)(pressure to get that wedding done soon)  she really is my gem, shes just some one you will love. SO put Australia on your visit list, we can pick you up from Melbourne, its only 3 hours save you catching a train...  ok, back to fiddling before my team find out Im not as smart as I tell them I am....Im really not haha....cya

spoke too soon, should have left it alone but back to rx aok, TX 100hz high, I suspect I need a stronger calibration signal on 5 or 15 mhz.  Still playing while you guys are sleeping.  Its not a biggie, just a small issue to sort out.  Got the IPad connected today to the Flex6700 , now thats amazing, even with my little 100hz issue, people were aok as I would just tune to 7.104.9 to get a perfect result on 7.105 both ways.  Ipad software works beautifully, some need to now get cracking on upgrades to routers, extended wifi systems for this 5 acre property.  The fun is only just beginning, even my 13 year old ham who has had his license since he was 10 years old is totally intrigued, especially when I said about the internet upgrades....Im no fool, hes thinking gaming, not radio haha...But good to see him show some interest in Ham radio as well, good balance with hit IT aspirations.

HI Tim,  Admittedly, this is one of the more simple operations of the Flex that 5 year olds can do, at 52, no matter what offset results from the UT signal, im not seeing correct calibration only on both Rx and TX where befoe I have said TX.  Brain now in gear.  rx, thats well, not ok, because if I have to drop to from 7.105 to 7.104.9,  suppose I have basically moved both the TX and RX down 100Hz, (by the way now 200hz after playing with time signals.  (The signal from the last chinese time signal was admittedly a bit low)

You all on here are so helpful its not funny, I'm more mad at myself as at one point, i had a good strong time signal get me right on frequency while i had no N1mm software running.  Is there any other area I could be missing, apart from the time synchronizing/calibration?   At your xmas party, you can say, hey we had this 20 year veteran of Motorola who couldnt setup a simple freq calibration, I know lots of Motorolans names to use instead of mine haha.  No stress re time, we will work it out with you guys, I obviously am presetting my xit to trick it or you could use the rit the reverse way, but its one of those moments down under where you go, mmmmmm what am I missing, its something simple...
Hey, by the way, you do a great job over there, I see a lot of your comments, we should have head hunted you 10 years ago when my business partner was yelling at Malaysians to learn English and follow his directions...We were heavy into GPS TAxi/couriers/Defense etc)He ended up learning fluent bahasa Malay, marrying a muslim malay wife helped that issue.  Hes Australian as well, we are good on football scores when our team is winning, no where to be seen when our team is down 5 goals haha...We now are primarily only defense contractors, I still support Tom at Optibeam and Val At Acom for the Asia Pacific region but they are great mates anyway.  We have been doing deals with them since the early 2000 era.  A lot of gear does not always go to hams from these two suppliers, both are very versatile, overworked like the flex team, but very very versatile.

PS...I love what you have done with Version 2, I dont think a lot of people understand the hours, previous beta testing and then the hours of tightening up the package after the fact.  Great Job Tim and to your team, holding a product back a little, very wise choice.  Every time we bow to our clients time restraints, we always regret it, and now, even if we are into penalty clauses, we just have to wear them as they are going to hit us with them anyway if the package has even one flaw in it.  Better to do the job right first, V2 is a great example of Flex and its team using the 7 levels of engineering we were all taught and applying them..

have tried all the time signals ie 5,10,15 and propagation now a few hours into the evening a lot better, unfortunately, each attempt brings around the same reult of a high of 200hz? Strange one for sure.

is there away of tricking the offset in ppb manually?
ie 120hz equals an offset of ???? ppb.
or an internal osc that can be set to sort the small 120hz, I imagine not being SDR.
We are all qualified here to do what we have t do but just want to follow your instructions as best as possible.  The time signal is a good 5 x 9 on 5mhz but still offset is around 120hz high.  Going to check around 2am again and see how propagation is with al tie signals. I have a conference call with Motorola anyway, so I will see how we go.
cheers

I think Tim meant the 'old' 1.10.X manual -- section 31.10.  There's a very brief description there of hitting the 'Start' button, but it isn't clear how you go about 'setting the radio' to the calibration frequency.  Again, a little more detail for us 'newbies' would be a big help.

Got it figured out.  Best bet is to open up the Band selector and tap on the WWV button.  This will automatically set you on 15.0000 Mhz.  Make sure that WWV's signal is audible -- doesn't have to be completely clear, but at least should be 4x6 or so....
Then, go to Settings menu (at the top), Select Radio Setup, then the Rx tab.  With the radio still tuned to 15.Mhz, the  value in the Cal Freq box should be "15".  Then click on the Start button, and the radio will chug away recalibrating itself to 15.0000 Mhz.  When all done, you should see a new value in the Offset box.  When that shows up, you're all done!

Thanks... it only took a second and now shows a zero in offset so I guess it's OK

I honestly have never run this cal.   So I tried it while remoting into my radio using 2.0.  

Before I started I was at -2.  Now I live in Fort Collins which means I can literally see the antenna farm for WWV. 

I hit start and it switched to 15 Mhz and there was a very nice very strong (as expected) signal.  It sat there for a while and came back with a computed offset of: -492.  I repeated it several times and I still get -490 or so.

Is there a valid range to this?  I do leave my radio on full time so I wonder if the value varies based on heat?  It would make sense.

But I guess I'm wondering if -492 shows a problem or pending problem?

Of course, there is a valid range and you are well within the range or you would have received an error message.  Your radio should be warmed up before calibrating.  Usually, 30-60 minutes is sufficient.

But I guess I'm wondering if -492 shows a problem or pending problem?

No problem.  XOs age over time and need to be corrected for that aging process. On the non-GPSDO radio I have I run it every time I upgrade to a new general release of SmartSDR just to make sure I am dead on frequency.

I am assuming this procedure does not need to be run if you are using an external 10Mhz reference.

Hi there,

as I have never had a good reception of WWV with my simple antennas.. Is anyone experienced what time signal transmission to use in Europe (the russian one at 9.996 Mc?) and if the procedure is the same if you don't use frequencies like 5, 10, 15 Mc??

Thanks and 73

Burch, it can be run with an external source to make minor corrections to the source.  My Rb reference clock is a little off, so I have used the frequency cal routine to fine tune it.

I wonder just what the number represents... sometimes it's 1000 or do and sometimes zero but what does the ppm represent in terms of frequency error??? Can't find anything in abt manuals I have that even mention the calibration process... was it left out??

It should be relatively constant on multiple runs using the same frequency reference standard.  It is the amount of correction needed in ppb (parts per billion) to put the reference XO on 10 MHz.  The value changes depending on the reference frequency
