Frequency Variation FlexRadio 6700 SmartSDR 2.0 over SmartLink

Thomas Dias

Hello, I have noticed after upgrading to SmartSDR 2.0

Doing remote testing I have noticed frequency variation, it has varied upward when down.

Did anyone notice this problem?

I do not understand "upward when down"?? Please explain...

Thomas Dias

I've noticed a frequency stability problem.

Example at 40M I'm listening to someone on Mhz, 7,140, I have to make small corrections up or down.

Thomas Dias

In the display the frequency remains fixed but I hear variation in the voice.
As if the frequency varies, when I transmit the people also inform me that it is varying.

Prior to doing any upgrade I always export my profiles.  After I do any upgrade, I always do a factory reset of the Flex, then import profiles but making sure I do no include the Preferences.

If you haven't done this, I suggest you give it a try and see if the problem goes away.

I recommend that you frequency calibrate your radio.  After you do that, tune to a strong frequency reference signal (like WWV).  The carrier should be a straight line on the waterfall.  if it isn't, then open a HelpDesk ticket so we can investigate.

Thomas Dias

hi Tim, how to calibrate ?

Tim - W4TME

Open the RX tab in the Radio Setup and run the frequency calibration.  You will need a strong reference signal, like WWV or one of the other frequency standards.

Tim - W4TME

If the signal is varying in frequency, a frequency calibration will not fix that problem.  Like I said, if it isn't straight, open a HelpDesk ticket.

Thomas Dias

hi Tim, i have done calibrating, but i note in 80M don't show me spectrum scope, only Waterfall, you have other tips..

change values of spectrum by sliding scale on right side

Thomas Dias

Hi Chris.

I tried to do this, however in 80M it seems that there is a bug in the scale, I tried to close the slice and open another but it comes back the same.

Chris DL5NAM

can you make a screen shoot from this part of your SSDR and show here?

Tim - W4TME

I think you should address one issue at a time.  Resolve the frequency variation before starting on a different issue.  Since you will be checking frequency stability on WWV (10 or 15 MHz), the 80m band issue is not relevant to this particular issue.

Thomas Dias

Hi.

In the upper right side has the two arrows, up and down both are locked do not work, but I did a test opening a new slice in 80M when I do this back the Scope band for the two. And when I close it disappears into the other.

Thomas Dias

Hi Tim,

Frequency variation seems to be normal not noticeable plus variation.

i will do more test  at nigth

Tim - W4TME

Change the magnitude of the signal strength scale on the right by using the up/down arrows located at the top of the scale.

buttons don't work corretly

I noticed the Quality Meter was showing 2 yellow bars, not that that has anything to do with Tom's reported problem. However, noticed that on my radio this morning as well.

Thomas Dias

Hi Bill, wifi level is low but works perfectly, in others band, Spectum Scope work good.

Tim - W4TME

Thomas, the scaling controls work fine.  Are you clicking on the small triangles?

Bill, if your comment has nothing to do with the post, adding it just adds to the confusion and degrades the signal to noise ratio of the replies.  We are trying to help Thomas, not muddy the situation.
