Default power up screen which you can change.
Meters have pedestal bar graph.
Change settings via touch buttons down the side.
IF plot shows shift, width, APF, notch & contour - great for FT-991A.
Displays transceiver Zulu (GMT/UTC) & local time.
Voltmeter for SOTA / POTA / field day battery monitoring.
Large vivid BAR meters are ideal for quick information.
Perfect for digital modes like FT8, FT4, Etc.
Change settings via touch buttons down the side.
Displays parametric microphone equalizer based on transceiver settings.
Touch screen changes frequency & level for each band.
TX bandwidth for selected mode shown in red.
Mode automatically updated by transceiver - can also be selected.
Automatically shows PARA or PPARA based on transceiver MIC EQ & PROC settings.
These settings can be saved or loaded from internal EEPROM or SD card.
CatTouch can be used to transfer settings between compatible transceivers.
Settings stored in small, easy to email, text files.
Drag a curve to change levels (base/mid/treble).
Touching SSB,AM,Etc shows speaker equalizer for chosen mode.
Red lines show LCUT & HCUT freq / slope if turned on.
FTdx10 & FT-710 are the only models with speaker equalizer.
Works with all models that have an internal clock.
Local is calculated from transceiver UTC time.
Set local offset on CFG screen (+/- 14 hours, 15 min increments).
Clock is great for SOTA / POTA / field day & log book entries.
Handy 2.4GHz WiFi channel scanner.
Ideal to find least congested channel.
Plots SWR response for the currently tuned band.

This screen allows you to customize & calibrate Cattouch.
Slide show 480x320 JPG images from SD Card.
Great for displaying awards, QSL cards, Etc.
Touch as close as possible to the arrow point.
Use the provided stylus & be as accurate as practical.
Easy power connection via 2.1mm jack or screw terminals
FT-710 version has no power switch, socket or screw terminals

Unzip the file & copy CatTouch.fw to FAT32 formatted SD card
This firmware file must be in root folder like D:\CatTouch.fw
Unmount / eject SD card from computer to close file
On FT-710 turn off transceiver & leave CatTouch connected
All other models unplug CAT cable from CatTouch
Insert the card into CatTouch & turn it on (FT-710 turn on transceiver)
CatTouch automatically finds new firmware on SD Card & installs
Do not turn off CatTouch or remove the SD card until it has finished & restarted
Once new firmware installed, Calibrate Touch screen shows
You MUST use the provided stylus & touch each arrow when prompted
If you touch wrong area, touch calibration will detect an error & repeat the process until you get it correct
The trick with calibrating the screen is to put your glasses on & use the provided stylus
The screen has a resistive touch panel so the stylus must be hard & smooth so as to not scratch the screen. A soft stylus will not work.

Includes short microphone port cable
Same socket, same CAT signals as rear port (RXD, TXD, GND)
Works independent to rear CAT port
Handmade in New Zealand
FT-857 & FT897 are great "shack in a box" transceivers.
With digital modes like FT8 now so popular, a second CAT port is often needed.
If rear CAT is taken up with a tuner or linear, 2ndCAT provides a much needed 2nd CAT port.

Isolated USB sound card with VOX PTTFor transceivers requiring a USB audio interface.
Adds digital modes to Amateur, Commercial & Military transceivers.
Unlock digital modes like FT4, FT8, JT65, PSK31, RTTY, FreeDV, VARA, Etc with USBRigLink.
Provides seamless, isolated audio performance with VOX PTT circuit.
Superior Audio Isolation
High-quality Bourns isolating transformers ensures complete isolation of audio signals,
helping to prevent ground loops and RF interference.
Dedicated USB Audio Codec
Integrated CMedia audio codec converts analog audio to USB data,
delivering crystal-clear sound to and from your computer.

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
