Has it been determined by anyone yet, whether the IC-9700's drift is due to TCXO thermal cycling, or a voltage regulation problem?  (or even some combination of these)

Potential fixes for either of these causes could be very different from each other.

I asked the same Q earlier. But I'm not opening mine at this point.

Hi. Belonging to the 9700.io Group, I have seen that Icom Europe has made a firmware change to eliminate the 'drift' issue.
However, we'll have to wait for Icom Japan to make it official.
I LOVE my 9700 and since I don't do EME or FT8, my radio has performed orders of magnitude over my 271A (with optional Mutek preamp).
Lots of guys on the 9700.io Group have reported making MANY FT8 contacts on 70 CM with NO problems.

So all the 9700 haters should move to a different radio, they can't afford. ha ha

Something else that is broke, how about all of the software titles that don't support the 9700?
N3FJP - Nope
WSJT - Nope
FLDIGI - Nope
JS8CALL - Nope

The 9700 is a great rag chew rig. Some of us would like to do more.

The 9700 will be fully WSJTX supported in the next mid-July general release v2.1.0 I got this from Joe Taylor himself. In the mean time you can run WSJTX using 2.0.1rc5 not 2.0.1.

Actually if you want to marry up WSJTX with the IC-9700 v2.1.0rc7 has just become available. It can be found here.

Thanks for the links Valentino, both upgrades went well.

Does the “sync to ref in” now mean it will lock to an external rubidium or GPS 10 MHz standard to operate in the same way that test equipment does? ie no more drift...

It would appear so. I am using a Leo Bodnar GPSDO tied to the IC-9700 and can see (from a cold start) constant ongoing adjustment the LO REF setting......after the radio has been on a while it settles down and there is very little adjustment change over time.

 I am reading discussion on the IC-9700 email list as people are trying out this firmware release. Early indication is that there is a marked improvement in the whole drift concern; but ongoing formal testing is being done to quantify it; particularly on 23cm (1.2Ghz).

I wasn't aware that WSJT-X had been updated for the IC-9700.......however, I've been successfully using it prior to this by changing the CI-V interface address in the IC-9700, to that of the IC-7300.....effectively making the software think it's talking to the IC-7300......it works perfectly. Then, I merely removed all band info and references to HF bands leaving 2m, 70cm, 1.2Ghz as available band options.

My understanding is that it's not phase locked, but more of a constant "compare and correct".  In talking to my friend though, he suggested this seemingly inferior method of frequency stability might be a good thing because if the 10 MHz reference has phase noise on it and an otherwise clean oscillator is phase locked to it, the phase noise will be imposed on the clean oscillator at least within the bandwidth of the PLL.

This is really funny information.... What does it have to do with the ICOM IC-9700 performance?
