Tnx Bill....it sure would be nice if it would TUNE (for the RF-sensed auto ATU) on every band hop UNLESS "RX ONLY" was ticked.  When using multiband antenna with auto ATU, the TUNE burst would be great to "tune" the antenna if the next-up cycle is RX.  In my case, my antenna system uses auto ATUs at the feedpoint.

Hi Ken,

you can do that with a minor limitation. Create a symlink (hard link on MS WIndows) so that same log file is visible in both instances log files directory. You will need to merge the two log files into one before doing that, just append one to the other omitting the header record.

The limitation is that QSOs made on one instance will not be visible to the other until the log file is re-scanned ("Setting->Colors->Rescan ADIF log") or the instance is restarted.

If the Call 1st check box is clear then the system will wait for you to select a QSO partner.

Ken,

the DDS is phase continuous when doing FSK frequency shifts. The ramping can be disabled in ramped-FSK mode by clearing the TRIANGLE bit if necessary. I did say that any F1/F2 swapping would need to be done in dwell time mid-symbol, probably just prior as at mid-symbol in ramped-FSK mode it is time to flip the FSK input to start the next frequency change if there is one. So I don't think any of your questions above are relevant or unanswered by the data sheet.

Hi Andy,

non-linear ramping is well defined for that DDS, the ramp control can be changed and timed on the fly as I said before. Even if the ramp is divided into a few segments with different slopes it will probably be better than trying to tweak the DDS in single frequency mode at exactly the right intervals to generate anything like a Gaussian filter. In fact I suspect a linear ramped-FSK will be better than any attempt at a piecemeal generation a Gaussian filtered MFSK, certainly much easier to generate using the DDS chip's facilities for it.

My interpretation of the datasheet, as below, is that the 9852 can perform non-linear transitions.  I think that the more difficult obstacle to overcome with respect to using the auto frequency changing mechanism in this chip, is that the frequency shifting mechanism in this chip seems to be designed only for two-tone FSK operation.  Even then, the non-linear frequency shifting looks to require constant updates of the delta frequency register during the transition between the frequencies.

Ken
KC6PUQ

-------- From Datasheet --------
 Although linear sweeping, or frequency ramping, is
easily and automatically accomplished, it is only one of many
possibilities. Other frequency transition schemes can be
implemented by changing the ramp rate and ramp step size at
any time during operation.
Frequency ramping, whether linear or nonlinear, necessitates
that many intermediate frequencies between F1 and F2 are
output in addition to the primary F1 and F2 frequencies. 


locked Re: FST$4W in a PIC #FST4W

Bill Somerville
 

Hi Ken,

the DDS FSK features are probably designed for 2-FSK where F1 and F2 are fixed, FST4W is 4-FSK so it gets a bit more complex as the next tone shift may be to higher or lower frequency than the current F1 or F2 frequency. The problem as I see it is that although you can exchange F1 and F2 values you will need to avoid changing the one that is currently being used to synthesize the output. Hence my suggestion that, when F2 would need to be set to lower than F1, you could set the one not being used to be equal to the one being used during the dwell time when there is no ramping (mid-symbol) then flip the FSK input, which would not change the output frequency, then set the register that was originally being used for synthesis while maintaining the F1 ≤ F2 requirement for ramped-FSK operation.

OK, I do see that but I see nothing that says F1 has to be the initial frequency, talking only about ramped-FSK mode because, per the datasheet:

The purpose of ramped FSK is to provide better bandwidth

Going back to my second comment in the thread, and without actually working out the details, I have to believe that the process of sending out a stream of symbols with both upshift and downshift of frequencies must be possible with the mechanisms in this device (ramped FSK of course) otherwise the stuff in this chip would not have much value.

Yes?

Hi Ken,

that device requires the F1 register be the lower frequency when using *ramped-FSK* mode, in non-ramped FSK mode the two registers may be either higher or lower than each other. The ramp from F1 to F2 or F2 to F1 depends on the last change of the FSK input pin.

From the look of the curves for BT=1 and BT=2, at any one time only the contribution from two pulses need be taken into account.  The contribution from pulses further away are too small to contribute when using a table-based approach to generating the GFSK waveform.

The next stage, when time permits,  is to write some code for a PIC that will sample at 32 or 64 times symbol rate, which is less than 1kHz even for the fastest FST15 mode, then send the results to a 48 bit DDS.
 It needs to be a 48 bit device - I use the AD9852 - as a normal 32 bit one is too coarse to give the correct increments at the slowest modes.

If I'm using contributions from two adjacent symbols, the curve stored in the table need only cover half the entire shape as the second half is a mirror image.  That will possibly,simplify the table lookup process.    I'll be using an 8 bit table, so frequency during the shift  will be quantised and I don't have the mathematical nous to calculate the effect that may have on spurii.

Andy   G4JNT

Hi Andy,

the AD9852 appears to directly support smoothed FSK transitions using what it calls ramped-FSK, I would have though that is a better approach that will avoid possibly noisy small frequency steps between symbols. The data sheet says that even though the ramp function is linear, it may be adjusted on the fly for more complex transitions.

Bill
G4WJS.

Hi Andy,

having suggested that, I am not sure how feasible it would be to generate ramped-MFSK using the FSK capabilities of that DDS since you cannot ensure that F1 is always lower than F2 without sometimes having to change either F1 or F2 while it is being used by the DDS. I say this because ramped-FSK has a requirement that F1 always be lower than F2. Perhaps it is a non-starter :(

73
Bill
G4WJS.

Hi Andy,

OTOH you may be able to set F1 equal to F2 (or vice versa depending on the last frequency transition direction) mid-symbol then flip the FSK input when; you need to exchange F1 and F2 to shift down or up (depending on the last frequency transition direction) to a new frequency for the next transition. That way you can do arbitrary frequency transitions while always keeping F1 lower than F2.
