Introducting the Leo Bodnar IC-9700 GPS Injection Board. This board is installed into your Icom IC-9700 and solves the issue of drift and frequency stability! Best of all NO soldering is required!
From the Leo Bodnar website - www.leobodnar.com/shop/
"This module allows locking the ICOM IC-9700 radio transceiver internal frequency reference, to an external 49.152MHz signal. If the internal reference is locked to a GPS signal, achievable ICOM stability can be better than 1Hz on all bands.
Installing this module inside the ICOM IC-9700 does not require any soldering or modification to internal circuitry. This modification is completely reversible and should not affect your warranty.
This module is designed to be used and has been tested with our range of GPS reference clocks signal sources."
In this video I show the installation and setup of the board in my 9700.

Nice demonstration of how the tuning the radio for lock works. I've seen quite a bit of uncertainty about the topic on IC-9700 mailing lists. It's simple when you know what to do, but I'm sure this video will be helpful for those who don't.

Nice summary of the board and installation Hayden. That should help people to make the decision to get GPS locked and onto 2m WSPR when they see how easy that is and you dont need to make any permanent mods to the radio to do it. Have had mine working for around 6 months now and never had an issue at all and mine runs 24 hours a day.

Thanks Hayden a nice succinct video. Best piece of advice is have the right screwdriver - JIS 2.0 - for the cover screws before you start. Another hint. The SO239 that is used for the 2m antenna on AU/US models is not soldered in place and can be simply exchanged with a N type socket by unscrewing 2 screws and swapping out. No need to remove the cover.

@VK2AAK Жыл бұрын

For anyone reading the above comment, be advised that this won't work if you're using the external GPS to steer the IC-9700. You need to disconnect the output of the GPS clock from the new SMA connector on the back of the IC-9700 and have it instead loosely coupled to the antenna input of the radio ... think along the lines of a piece of wire as an "antenna" from the GPS clock SMA output at 49.152 MHz with the signal being picked up by an antenna connected to one of the coax antenna connectors the 9700. That way the IC-9700 will be using its internal reference and you can adjust the REF Adjust sliders using a harmonic of the output from the clock as the CW source. You can use any harmonic ... 3rd at 147.456 MHz, 9th at 442.368 MHz or 26th at 1277.952 MHz.

Was my goto reference for finally getting the board in and setting up the frequency - am already impressed how rock solid it is, I actually use WSPR on 2M with my 9700 when I'm not chasing the 'birds' but cant wait to get into digital modes as the sats go over now as the frequncy will be far more stable.

When I installed the Bodnar injection kit I drilled a new hole for the Bodnar connection and left the 10 MHz ref in place. When I power the radio up, I leave the Bodnar turned off, and I turn on the 10 MHz ref sync with a 10 MHZ GPSDO connected like usual. This puts the radio very close to on frequency. Then I turn off the 10 MHz sync, and turn on the Bodnar, and the radio locks immediately to it every time. I repeat this procedure a few times a year, or when it appears the radio is coming out of lock. I use my rig mobile and It does need to be redone from summer to winter.

I’m about three years late to the party Hayden but thanks for the great video’s. I just did this install and the only thing that doesn’t go well for me is the tuning it back onto frequency. My 9700 is reading 144.100.18 then it’s on a beacon locked to 144.100.00. If I uncheck the GPS box and tune it down to read 144.100.00 on the 9700 it jumps up again when I check the box in the gps software. It’s driving me nuts. 😂

Question, maybe dumb, when you used your TPI link signal generator to create that 1200mhz signal, did you inject this directly into the front end of the 9700? If so, what db level did you set? I was looking at picking up one of those TPI signal generators, they look super useful.

@HamRadioDX 3 жыл бұрын

Do I just hooked it up to an antenna (a little test log periodic) and hooked the 9700 to one too. I just set the dB level to about -70 which was super strong. The lowest the TPI will go is -90, so you need more attenuation if you were to plug it into the radio, but... I didn't do that just in case I accidentally hit transmit and blew it up!

@BryanGrigsby 3 жыл бұрын

@@HamRadioDX So I just received my injection board and their mini GPS. When I enable the output via the software, it does weird things to my 9700. It's like it's distorting the received RF I might be receiving at the time. For example, turn on my RF generator, things look good in the waterfall. Enable the output of the mini GPS clock, and I get all kinds of RF on either side of the waterfall. I took a screenshot: imgur.com/a/ByweUoU No idea what's happening with it.

I saw another one of your videos, where the running fan would cause it to drift which sounds like a thermal problem. The new board looks like it also blocks air flow, I wonder how it would work with just adding the unconnected board. The goal would be to control rapidly cooling but not let it get to hot -constant temp regardless of fan state.

@HamRadioDX 3 жыл бұрын

The drift is really only an issue on longer transmissions modes such as WSPR etc on 2m. JT65 works fine especially if you have the auto calibration sync with 10MHz connected to the back. 1.2 GHz would be another story though

The drift is 1/10th as much on 2m as it is on 23cm. I've seen it drift as much as 30 Hz on 2m. That's enough to wreck decodes.

@kevinmccool3719 3 жыл бұрын

What is really going on with these companies that make such nice radio equipment but they can't simply install a stable master reference oscillator in them. People pay a premium for it already so a little extra cost for frequency stability and accuracy should not be an issue for most to pay a little more.

@stargazer7644 Ай бұрын

Because sub 1 Hz frequency accuracy at 23cm is not a simple thing to achieve when the inside of the rig is changing temperature during transmit cycles. That's why high end radios have external ref inputs. It's a shame that Icom screwed the pooch so badly with the ref implementation in the 9700.

Hey mate, the sync to ref button only does a calibration of frequency. The radio drifts due to thermal temperature changes around the oscillator. The latest firmware can continually track, but it's still not fast enough to stay on frequency. That said, it's good for probably 95% of situations.

@stargazer7644 Ай бұрын

Yes. If you have an external 10 MHz source connected, you can turn on the sync for a moment, then turn it back off, and then turn on the Bodnar. That's how I do it. However, the instructions with the Bodnar unit have you disconnect the 10 MHz ref cable so you can use the chassis hole instead for the Bodnar cable. So if you do it that way, your 10 MHz will no longer work. I drilled a new hole for the Bodnar connector on the back panel and left the 10 MHz connected.
