I've received a reply from Jackson Labs re my email.

FYI...

Hello Adam,

Thanks for your interest in our products! I am a HAM too, N6GSJ. Cool item the Icom unit, I have a Yaesu 991A and love it. Talk to New Zealand and Australia on FT8 20/40M from time to time, good propagation usually.

Does the Icom unit accept an external 49.152MHz input? I read in the specs it looks to an external 10MHz input, so I guess you and your team would open the unit and replace the internal oscillator?

The international pricing for the LTE Lite 24.576MHz is PN: 100422 for $182 each. Quantity breaks are available for >100 units, Giovanni can quote you.

Unfortunately the unit talks NMEA at 38,400 baud, and changing this is quite time consuming, as the software team is very busy right now. We could consider it for orders of 100 units or more. Maybe if someone can hack a PIC or Arduino etc to translate 38.4KB to 9.6KB that would be the fastest way to accomplish this?

Hope that helps,
Bye,
Said

No doubt all are already aware of the Leo Bodnar GPS units, but I'll re-post a link. Whilst expensive they may be another option.

VK2IJM recently GPS locked his FT847 using one of this units with a switch between the internal and external oscillator. Perhaps something can be implemented with the 9700.
I visited Rex 7MO yesterday who was testing his on the bench. He experienced significant drift on the digital modes once the fan operated.

Already issues to be solved, given that VK hams had input allegedly to the design why is this an issue?
Will ask the JA nagoya boys am sure they will solve it, but as radio nya in usa wont be much from them yet.
maybe next month along with the nya rt systems software.
Anyway only need the radio for summer tropo and es and 1296 with fall back to proven 910s.
Dont need such a radio for the two hour morning local rush hour.



Latest is 30hz drift when fan kicks in
Means wspr bit suspect
so leave the fan on continuous
All sounds a bit mix and match for a new rig.
Early days, maybe not best to buy first run?
Hear the sellers laughing all the way to the bank with the cash this week.
Mine included.. :crazy:

Why oh why wouldn't they supply the appropriate 8 pin din plug in the spares kit?

Of course the other format from Kenwood 8 pin.

Had a real scrabble around in the junk last night to make up the amplifier interface lead in time for the Meteor Scatter net this morning

Here is the receiver test data from http://www.sherweng.com/table.html
Added 04/11/19
Summary, with preamp on.

Noise Floor = -145 dBm,
AGC threshold = 0.18 uV,
100kHz blocking = 111 dB,
Sensitivity = 0.082 uV,
LO phase Noise @ 10KHz = 130 dBc/Hz,
Ultimate filter = 100 dB,
Dynamic range 20 kHz and 2kHz = 74 dB.

Better than the IC-9100, FT736R, IC-275H, but worse that the IC-706Mk2G ?, sorted by third order dynamic range narrow spaced.
Time will tell if the 9700 is a real improvement in receiver performance.

Strangely, Sherwood never tested the IC-910, the radio that the IC-9700 essentially replaces.
This would be the most relevant comparison.

I'm looking forward to seeing the ARRL Lab review of the IC-9700.
They are the only reviews worth reading, and do not need to be sugar coated so as to not upset advertisers.

I am amazed that there has been almost no discussion about the short (TX) and long term drift on the IC-9700.

Other forums have discussed it at length.

I don't have an IC-9700 and may never get one until it can be used on all bands an WSPR.

Max drift during TX for WSPR to decode is about +/-5hz in the 2 minute TX window.

From figures quoted elsewhere It may just squeak in on 2mx but not on 70cm or 23cm.

It appears that the drift during TX is due to the fan coming on as soon as the PPT is activated.
Apparently there is no menu setting to have the fan on continuously.
Any manual change to achieve that would void the 5 year warranty.

The external reference lock facility is poorly implemented as it is a one time calibrate and not
a continuous lock.

Good luck to the early purchasers.

Rex 7MO was testing this. I haven't heard his full results but was seeing close to what you have reported. The issue seems to have plagued some Icom radios in the past such as the IC7000 (aka the banana trace rig).

Rex has done some great work in this area. His figures indicate that on an IC-9700 that is thermally warmed up on receive the 1st 2 minute transmit cycle drifts about 30hz on 2mx. Further TX cycles after a break are around 4hz. It should not be "rocket science" for Icom to fix that.

It has been discussed for several days on the 9700.io group.

Rex, VK7MO has made several posts there on the subject of frequency drift on his IC-9700.

Looks like I should buy the IC-9100 from VK6 that was advertised with a Reflock as part of the deal :crazy:

Nice box, cardboard no foam packing so environmentally a green tick.
removed old IC910A ex JA.
Hooked up new 9700 serial number 12001248 (whats yours for tracking warranty and any issues).
entered warranty before turning it on.
Stored all boxes away safely this guy does not sell on radios minus the box, which some people seem to always do. Keep your boxes for RON :om:
Hooked adaptor lead from old Yaesu power to new plug.

Initial
2M Preamp and attenuator work same as 910H so 2M mast head all working.

Off to read the manual (the English one) why do we get foreign language handbooks included?
Off to load the OPC 2350LU

cheers..

Worth a few comments
why would you put a $2500 radio on wspr?
VK5GF and I and 7HH only ones on anyway so my $350 IC910A fromTokyo ham fair is all that mode is worth.
APRS tells me more about 2M prop than WSPR anyway.

As for good luck
I work my backside off in middle of night fixing tv stations because we cant find any new chums to take on the work load.
50 years this July BOCP #7 and still working at 73YO.
The radio is one months pay, so be it.

50 radios sold in a week in VK3 unknown in VK4 so 50 mugs out there at least :lol:

Same reason I just bought an 6 year old 86GTS..with 4300 km on the odometer from a mate and driving it 2000k to Dubbo nationals on Saturday
if its a bummer like the 86GT, Cost $35000 bought for $20K,
we will see them under $2000 like the ill-fated FTDX3000 and 1200s and the crap 9981 991A..asss fell out of resale...

Its only money or a good set of golf clubs..
You cant take it with you old timer..

No mike holder either?
