Note: FT-710 still has CAT issues despite Yaesu firmware updates.
MSHV is a reliable WSJT-X alternative with no issues. FT-710 has issues handling multiple CAT ports. WSJT-X errors due to FT-710 "?" response.
Try MSHV by LZ2HV.
It works great and doesn’t error!

Unzip the file and copy CatTouch.fw to a FAT32-formatted SD card.
This firmware file must be in the root folder (e.g.,
D:\CatTouch.fw).
Unmount or eject the SD card from your computer to close the file.
On FT-710 , turn off the transceiver and leave CatTouch™ connected.
For all other models, unplug the CAT cable from CatTouch™.
Insert the card into CatTouch™ and turn it on (for FT-710 , turn on the transceiver).
CatTouch™ automatically finds new firmware on the SD card and installs it.
Do not turn off CatTouch™ or remove the SD card until it has finished and restarted.
Once the new firmware is installed, the Calibrate Touch screen appears.
You MUST use the provided stylus and touch each arrow when prompted.
If you touch the wrong area, calibration will detect an error and repeat until correct.
Tip: Put your glasses on and use the provided stylus.
The screen has a resistive touch panel, so the stylus must be hard and smooth to avoid scratching the screen. A soft stylus will not work.

Replaced by CatTouch™ TTL for Old Yaesu
The 3.5" CatDisplay™ hardware is now being gradually phased out as production moves to the newer CatTouch™ 4" platform.
This newer hardware provides a better long-term foundation and is easy to keep updated, with simple SD Card firmware updating for future improvements.
The TTL version of CatTouch™ 4" is compatible with all older Yaesu transceivers currently supported by CatDisplay™, making it an excellent replacement platform.
Initially this version will operate as a display-only unit, with touch support not yet enabled, although this may be added in a future software update.
This change allows continued support for older Yaesu radios while moving to a more modern, flexible, and easily maintained hardware platform.

Supports Power-Over-Serial (POS) for compatible CatTouch™, CatMeters™ & CatKnobz™ installations
The FT-710 provides USB-CAT on CAT-1 and CAT-2, plus a separate CAT-3 port on the rear TUNER/LINEAR connector.
CAT-3 is TTL-level, so RS-232 accessories won’t connect directly.
CatAdapt™ converts CAT-3 into an RS-232–compatible CAT connection, so your accessories can plug in and just work.
This lets you run USB-CAT to your computer (MSHV, WSJT-X, logging, rig control, etc.) while simultaneously running RS-232 CAT to your accessories.
No swapping cables, no compromises.

Turning ideas into quality radio gear.. Welcome to CatMeters.com & CatKnobz.com,
..where passion meets craftsmanship in the world of amateur radio.
This isn't a faceless corporation; it's just me, Chris ZL1CVD..
Timaru grew from an 1839 whaling station established at Patiti Point.
Present-day population is over 48,500.
My station includes Yaesu FT-100D, FT-818ND, FT-857, FT-897D, FT-710, FT-991A, FTdx10, FTdx101D, FT-1000MP MkV Field, and various handheld transceivers.
In addition to exploring different communication methods, I find joy in collecting and restoring military radio equipment.
Test equipment includes Rohde & Schwarz CRTU-RU, CMU200, HMO1002, NGMO1, NGMO2, Aeroflex 7100, IFR1900, Agilent E6621A, HP 8924, and Bird 43 with slugs & loads.
But my true devotion lies in developing innovative amateur radio products.
From CatDisplay™, CatTouch™, CatMeters™ to CatKnobz™, each creation underscores my dedication to enhancing the radio experience for both novice and seasoned operators alike.
Days are a blend of designing, soldering and programming.
Beyond the technical aspects, I enjoy sharing my knowledge & assisting like-minded individuals.
Remember, my friends, the joy isn't just in picking up the phone to contact someone globally;
it's about creating that connection, sharing experiences and extending kindness.
So, as you explore my offerings, stay safe, stay well, and remember the essence of amateur radio

Military History
Introduced in the mid-1970s, the AN/ARC-174 was widely adopted by the U.S. Navy, U.S. Army, and Royal Navy.Its versatility allowed for installations in military helicopters, fixed-wing aircraft, land-mobile and marine applications.
It became standard equipment on aircraft such as the HH-60H Rescue Hawk, SH-60B/F Seahawk, MH-53E Sea Dragon, and CH-53E Super Stallion.
With additional hardware, the AN/ARC-174 supported secure voice and low-speed data services, extending its utility beyond conventional voice communications.
Civilian Applications
The commercial counterpart, the Collins 718U-5, served extensively in civilian aviation for long-range operations.It was installed in aircraft such as the Boeing 747, DC-9 series, and various Gulfstream business jets.
The 718U-5 earned a reputation for reliability and performance with coverage from 2 MHz to 30MHz with SSB, AM, and CW modes.
Higher-power amplifier configurations (400W) were available for long-range commercial communications.

Military History
Introduced in 2012, the RF-7800H-MP marked a major advance in tactical HF communications.Adopted by the U.S. Department of Defense and over 20 allied nations for secure beyond-line-of-sight operations.
Used in Afghanistan to link remote outposts where terrain prevented line-of-sight or satellite communications.
Deployed by forces in the Middle East during regional conflicts including the Yemen intervention and counter-ISIS operations.
Also confirmed in Ukrainian battlefield use, where resilient HF links proved critical against heavy electronic warfare and SATCOM disruption.
