First look: SEQ-9700/10

Post by VK4GHZ » Wed Nov 13, 2019 7:46 pm

Hi all

The SEQ-9700 is a purpose built touch-screen based sequencer for the IC-9700.
There are now 66 user configurable settings via its set menus.

Yes, 66!
You are not locked into settings that someone else thought you might want.

It is CI-V driven and plug 'n play.
It will not void your warranty as there are no modifications required to the IC-9700.
Just connect it up.

Some history with the old Rev 2 SEQ-9700/9 prototype with 9 outputs.
That being PA, LNA, and Antenna Switching relays for each band.


Project development started in March 2018, and this PCB was designed May/June 2018.
Long before the actual IC-9700 became available!

As you can see above, lots of Veroboard mods have been tested and assessed during hardware development.

Fast forward almost 18 months, and we now have the Rev 4 board and the SEQ-9700/10.
The 10th output being the addition of a "Transverter mode" relay.


A few custom cases were recently laser-cut, CNC bent, and then powder coated.
I'm really happy with the satin black finish, although it does tend to show finger marks.


Rear panel connectivity:

The 9 main output relays appear on the DB15 and can switch to GND or a positive voltage, each being configured by an internal jumper. There is also an internal diagnostic LED associated with each relay for visual confirmation of relay activation.


For interfacing to the outside world you can use a standard DB15 male connector, or for a no-solder solution, one of these breakout adapters with screw terminals.


A mini-B USB port is provided for PC T/R control when using digital modes.

A genuine FTDI USB transceiver chip is used, and unlike the cheap eBay FTDI boards out there, this FTDI chip is properly terminated with the correct R & C components.

Whilst you can buy a complete cheap Chinese FTDI board (delivered) for less than a genuine chip only, no driver issues are expected with using a genuine FTDI part.


A proper 8-pin GX16 connector has been sourced for plugging in the mic, the same type as fitted to any OEM transceiver.
These are quite different to the commonly available 8-pin hobbyist mic sockets found on eBay and Jaycar etc which leave very little thread to properly screw on the locking ring.



Running in transverter mode.


Xvter band is selectable and display is offset by your designated LO freq. Both N.O. transverter relay contacts appear on the DB15 so you can switch your transverter system how you like.

I have not investigated silk screen printing, and to be honest, that will only increase the cost for not much benefit.
Each rear panel connector is unique and will be detailed in the manual anyway.
Once you plug the connectors in, you're unlikely to touch them regularly.

And the front panel?
Well, the touchscreen tells you what it is when it powered up anyway!


I am not keeping any "list" as such but when the time comes regular VK Logger Forum users, (those who understand that technical content is better posted on a Forum rather than on living-in-the-moment and I-can't-find-it-again Facebook groups), will automatically jump to the top of the list!

T.B.A but affordable.
18 months of development won't be given away, and there is >4,700 lines of code in the main MCU and >4,500 lines of code in the touchscreen MCU.

Production numbers
Limited, as each of these is hand assembled, and I will be back concentrating on house renos during 2020.

SEQ-9700/10 More than just a sequencer.

Very impressive, Adam.

Well thought out and packed with features.

It goes without saying (but I'll say it anyway), put me down for one!

I like to be on the list
the usage as a sequencer for 3 in 1 is fully enough for me

Thank you for this NICE project.
Do you plan to do something more simple?
I have sequencers in each PA, so timing between LNA and PA is correct.
I am need only separate PTT outputs(by band) and delayed IC-9700 output(delay(possible to be constant 100mS) between PTT pressed and IC-9700 PTT activated).
Simple, something like Multi PTT for IC-910.
I understand that SEQ-9700 sequencer possible to configure for my needs, but I will not use all other GOOD options.

Best Wishes.

Hi Adam.
What a handy unit with much thought and many hours gone into its design no doubt.
Please include me when available.

Nice work Adam. Any ETA yet on when the units will be available for general sale?
Is there any pre-release manual or other information (ie: setup or configuration info) yet?
