<ul></ul><p>The Yaesu FT-991 doesn't store all information with the stored memory.</p>
<ul>
<li>Names aren't stored with the memory</li>
<li>CTCSS/DCS aren't stored with the memory (the FT-991 has a global setting for this)</li>
</ul>
<p>Probaly using the CAT commands for programming the FT-991's memory (and settings) seem a good solution for me, the CAT commands are documented online but there seems to be a little difference in the documented commands and the commands with the latest firmware of the FT-991.</p>

<ul></ul><p>I just ordered one of these (will sell my Kenwood TS-2000). Anything I can do to help when I get it?</p>
<p>Is there any other model with similar CAT commands and memory structure that I might use as a starting point?</p>

<ul></ul><p>I have a need for cheap cross-radio-cross-model software and have been approaching Yaesu for information. Performing "Serial Port Monitor" traces and dumps does not provide considerably useful information either. </p>
<p>Usefull communication trail provided at the base of this posting. This communication trail could be used as a learning point for obtaining needed information from Yaesu (i.e. japanese engineers can be extremely literal).</p>
<p>I would suggest that the "status" of this project should be upgraded as the numbers of these radios out there are now considerable.</p>
<p>...............</p>
<p>Dear Steve,</p>
<p>Thank you for your patronage to the YAESU product.</p>
<p>Unfortunately, you cannot write the memory tag using CATS API.<br>
In order to operate the radio as you mentioned, you will need a programming software. Please visit the RT Systems’ website and purchase one for FT-991.<br>

<p>We hope this information is useful and thank you for your continued support to YAESU. We remain,</p>

Subject: CAT Programming - Memory tags FT-991</p>
<p>Hi,</p>
<p>I have been referred to this address via Tim Factor, one of your agents (email attached). Please note that this is not a service related issue but is an issue of general support – how to actually do something that is not documented.</p>
<p>I see from the CAT reference for the FT-991 that it is easy to use CAT codes to upload data to memories, yet I note that the FT-Systems Software also writes the "Memory Tags" as well.</p>
<p>How do you write the memory tag (i.e. to label a memory with say a repeater name) to the radio using the CAT programming API?</p>
<p>Once you have loaded memories, along with label tags, how do you read this data back?</p>
<p>Can you please forward me information on how to do this on the FT-991, and perhaps make this available to the wider community via the CAT Technical Supplement? </p>
<p>Thanks</p>
<p>Stephen I<br>

<p>Conclusions:</p>
<p>(a) CAT Code 53 50 has two main variants:</p>
<ul>
<li>SPR (53 50 52)</li>
<li>SPW (53 50 57)</li>
</ul>
<p>(b) After Execute of SP R or SP W appears to be the memory address, in HIGH, LOW-order byte format</p>
<p>(c) Next 3 bytes appear to be payload data - though it seems to increment in 32-bit increments. So what each octet does needs further investigation. - Which are data? What is the 3rd element? is it a Checksum?</p>
<p>(d) After a SP W there is an ACK (CAT Code 41) written back</p>
<p>(e) The SP R and SP w Commands Definitely appear to read/write a 32-bit number into the FT-991's memory. The data retrived above the set of "SP" sequences appears to retrieve addresses used to locate the start of the data table.</p>
<p>(e) I am not sure with the read back.... Assistance needed.</p>
<p>.....</p>
<p>A sample Excel sheet with data is attached.</p>
<p>Regards,</p>

<p>Hi Gregg & all, two things are needed to develop a drivers for a radio (any radio) in Chirp:</p>
<a name="A-willing-Developer-remember-this-is-done-pro-bono-in-devs-free-time"></a>
<h1 >A willing Developer (remember this is done pro-bono in dev's free time)<a href="#A-willing-Developer-remember-this-is-done-pro-bono-in-devs-free-time" class="wiki-anchor">¶</a></h1>
<a name="A-radio-in-the-hands-of-that-developer-Own-loan-crowdfunding-gift-etc"></a>
<h1 >A radio in the hands of that developer (Own, loan, crowdfunding, gift, etc.)<a href="#A-radio-in-the-hands-of-that-developer-Own-loan-crowdfunding-gift-etc" class="wiki-anchor">¶</a></h1>
<p>For example, I had one radio driver started in 2019 with a short loan, but I had to return it before driver completion; now in 2021 I got a gift of one of those radios again, support was completed in about 3 days (it was a super simple old radio, driver still on production queue to be reviewed & approved)</p>
<p>So a loan offer will increase the odds by tempting a developer with some free time to start development. </p>
<p>I'm a willing developer, but my county custom laws are a obstacle to ship any radio here, I have to use non official channels and that way is expensive and can take a while... (I live in Cuba island)</p>
<p>Cheers, Pavel.</p>

<ul></ul><p>Hi everyone,</p>
<p>I own a FT-991A with current firmware (as of 2022), and I am willing to learn what it takes to become a developer to help get CHIRP working on this radio. HOWEVER, I must advise that I am full-time employed so I will not have a lot of time in any given week. If this is acceptable to this community, please advise provide me a pointer to a "how to get started developing CHIRP drivers" page :-)</p>
<p>Cheers, Dave VK6KV</p>

<p>On the "CHIRP home page":<a href="https://chirp.danplanet.com/projects/chirp/wiki/Home">https://chirp.danplanet.com/projects/chirp/wiki/Home</a> there is a "Documentation":<a href="https://chirp.danplanet.com/projects/chirp/wiki/Documentation">https://chirp.danplanet.com/projects/chirp/wiki/Documentation</a> link. It is at the end of step @#2@ of the <em>To Get Started:</em> section. For some reason this hypertext link doesn't stand out as being a link when I look at in on my monitor. Click this link to go to the "Documentation":<a href="https://chirp.danplanet.com/projects/chirp/wiki/Documentation">https://chirp.danplanet.com/projects/chirp/wiki/Documentation</a> page.</p>
<p>At the bottom of the Documentation page there is a "Developers":<a href="https://chirp.danplanet.com/projects/chirp/wiki/Developers">https://chirp.danplanet.com/projects/chirp/wiki/Developers</a> link that will take you to the "CHIRP Developers":<a href="https://chirp.danplanet.com/projects/chirp/wiki/Developers">https://chirp.danplanet.com/projects/chirp/wiki/Developers</a> page. This is what I referenced quite a bit when I got started.</p>

Gil Kloepfer KI5BPK, <a href="https://www.kloepfer.org/ft991a/">https://www.kloepfer.org/ft991a/</a>, did a lot of work on mapping the memory of the 991A, I did find a few things he missed.
