Tyt TH-UVF9 Semi Eyes Free Guide
by Joseph Stephen 21 March 2016
[log in to unmask]

Physical Description:
Hold radio with the antenna at the top left, with the keypad facing you.
The Power/volume knob is to the right of the antenna. Turn it clockwise to
turn the power on and continue turning clockwise to increase the volume.
Turn it anticlockwise until it clicks to turn the power off. 
At the top of the front face is the LCD display.
Beneath the LCD display is the speaker grill with the Fun (Menu) key at the
top left corner of the speaker grill.
At the bottom left corner of the speaker grill is the Band A/B key.
Beneath the speaker grill is a 16 key keypad.
The keys are as follows, moving left to right, top to bottom:
1, 2, 3, up
4, 5, 6, down
7, 8, 9, FM radio
*, 0, #, VFO/MR/Exit.

Note the VFO/MR/Exit button is a single button which either switches you
between Frequency Mode and Memory (channel) mode, or exits one level from
the menu system. 
It is also used as a shortcut to save a channel if pressed immediatley after
the Menu button (see below).

On the left edge from top to bottom are Call, PTT and Monitor buttons.
The call button is used to transmit a 1750 hz tone to activate certain
repeaters. The button must be held in for two seconds to accomplish this.
The Monitor button is used to disable squelch to listen to weak signals.

On the right edge are two rubber flaps, one near the top which covers the
external microphone/programming cable jacks, and one right at the bottom
which covers the charging socket.

On the back, near the top, are two screw holes to afix the belt clip.

If your radio does not come with Voice Prompts on, you will need to get a
sighted person to turn them on:
1. Press menu, 
2. Use up/down to find Voice Prompts (menu option 19),
3. Press menu to select,
4. Press up/down to choose "on". 
5. Press Menu to save.
6. Press Exit until you leave the menu system.
7. A sighted person may also need to set the Beeps on in the same way.

Note: My radio came with both Beeps and Voice Prompts enabled so I did not
have to do this.
Note too that you should have a sighted person disable D Wait (Dual standby)
mode as it is just confusing. I find that I do not need to use the A/B
button since I stay on the same band and can tune to channels or frequencies
in either the 2m or 70 cm bands directly in either A or B. 
Calling the A and B bands is misleading. It is really just two receive
modes, both A and B modes can tune to the exact same frequencies or be tuned
to the same channels. Unfortunately there is no way of knowing which mode is
active.  

While I did manage to program my radio manually, it is difficult to set the
CTCSS/DCS for a repeater if needed without sighted assistance. 
I was able to program the radio using the Tyt programming software making
liberal use of the JAWS cursor as I'll describe later. It is not for the
faint hearted but I proved it can be done.
The software can be downloaded from 
http://www.tyt888.com/download.aspx?page=3
Other than the CTCSS/DCS settings, most of the rest of the radio's functions
are reasonably accessible.

Tip:
You can hear when you switch between VFO and MR modes because when you
switch to MR mode, you'll hear the voice announce the channel number. If you
switch to VFO mode, you won't hear anything. Thus, you can toggle the bottom
right key on the keypad and hear if you are in channel memory (MR) mode or
frequency (vfo) mode.
In Frequency mode, you can enter a frequency directly on the number pad, eg
439000 to tune to 439.000 MHZ. 
In channel mode, enter the channel number as a three digit number, e.g. 001
to go to channel 1, 128 to go to 128 etc. If you make a mistake, press exit
and start again.
As soon as the last of the three digits (for channel) or 6 digits (for
frequency) is pressed, the radio tunes to that channel or frequency.

The same principles apply in FM broadcast radio mode. toggle this on with
the FM radio button just above the VFO/MR button, last button in row three
of the main keypad.
You can again use the VFO/MR button to change between channel and frequency
mode though if you haven't yet stored a frequency, there will be no
channels.

To store a channel in regular amateur mode:
1. Ensure VFO mode is on. To do this, press the bottom right key on the
keypad until you do not hear a channel number. When not exiting a menu,
you'll hear a high beep. If you are in channel mode, you'll hear the high
beep and the channel number. If in VFO mode, you'll only hear the high beep.
2. Enter the frequency, e.g. 439000.
3. Press Menu.
4. Press VFO. The radio will say "Store channel".
5. Press the channel number, e.g. 001 for channel 1.
6. Press VFO to store and exit.

To store an FM radio station, first select FM radio by pressing the button
above the VFO button, i.e. second button up from bottom right. In FM radio
mode, you can again switch between MR and VFO mode using the bottom right
button. If you haven't yet stored any stations in memory, you will simply
remain in VFO mode.
Use the same steps as in the above list to store a frequency. The only
difference is that when you get to the channel number step, you must use the
arrow keys to choose the number as direct entry doesn't seem to work in this
mode.
To get around this, I simply pressed up arrow each time I wanted to store a
new channel so that the new channel was stored in the next available slot.
There are only 25 channels for the FM radio.


Programming the radio using the Tyt software and cable.
Note: The cable plugs in to the right side of your radio. The two pin socket
is beneath the rubber flap which opens at the front and is hinged along the
back edge. If you put your finger nail between the rubber and front right
edge of the radio, you should be able to lever the flap open.
The following instructions assume you are using JAWS for Windows. If you are
using another screen reader, the JAWS cursor will be equivalent to that
screen reader's mouse pointer, and the PCCursor will be equivalent to the
application's focus.
Note: in the following steps, the menus work fine with the PCCursor, its
only the actual locating of data on the main channel screen which you'll
need to use the JAWS cursor for to locate and left click.
1. Connect the cable and run the software.
2. Use the JAWS cursor to ensure you can read the screen.
3. Using the PCCursor, choose the Setup menu and ensure that you have chosen
the correct Com port for your USB to Serial adapter cable (which is what the
USB to two pin programming cable really is.
4. Choose the Transfer menu and then "Read from Radio" option.
5. Follow the dialog prompt. (You will need to press Ok to begin reading.)
6. You'll know if you can read from the radio by using the JAWS cursor to
check the messages in the status area of the main window toward the bottom
of the screen. If there is a failure, a dialog will alert you to this.
7. If you are successful at reading from the radio, the fun begins. If you
can't, the real adventure begins. You may need to choose a different com
port, or, like me, fix a nasty issue with the default Windows 10 driver
which was incompatible with my cable. I had to downgrade the driver from
version 3.6 to 3.2.0.0. I was able to get this from the Miklor.com website
where there are also good instructions for doing this. (See
http://www.miklor.com/COM/UV_Drivers.php)
8. To program the radio, locate the JAWS cursor on the first empty channel,
by finding A1 near the top left of the application's client area and
clicking on it.
9. You'll hear "edit". Now switch the PCCursor back on and type in the
receive frequency (e.g. 147.000.
10. Tab once. JAWS will probably say "Command1 button". this is not much
help but tabbing actually causes the program to fill in the transmit
frequency (this makes it easier to modify it since there'll be text to
locate and click on). (Do not click the button).
11. Using the JAWS cursor, locate the A1 text again up near the top left of
the UI and now you'll note the receive and transmit frequencies to the right
of this.
12. Using the JAWS cursor, click on the second frequency (the transmit)
frequency if you wish to change it for repeater use. (Don't forget to enable
the PCCursor to edit the frequency). E.g. you could edit it by deleteing
some of the digits and changing the number to 146.400 for a negative 600 KHZ
repeater offset.
13. Use the JAWS cursor to click on the following two comboboxes (as
appropriate) to the right of the transmit frequency, these are the Rx and Tx
CTCSS/DCS codes for the Repeater, they default to "None." For simplex
operation you can leave these as they are.
14. To the right of the two combos is a power option which defaults to
"high". I'd leave this.
15. Next is the word "Add" which allows you to add this to scan memory. Just
leave this one as well.
16. TO the right of Add is the "Wide/Narrow" combo. Click on this with the
JAWS cursor and Set this to "Narrow" or "Wide" as appropriate.
17. To the right of "Wide/Narrow" is a blank space for entering a channel
name, which we'll come back to in a minute.
18. To the right of the blank space is the BCL field which defaults to off.
Just leave this as well.
19. If you place your JAWS cursor on the o of off (in the BCL field), and
move left about three spaces (between N/W and BCL), and left click, JAWS
should say Edit. You can type in a 7 character name for the channel such as
a repeater's callsign. If JAWS doesn't say "Edit", move the cursor back to
the right to the "o" of "Off" and try again, The click area is about two or
three characters to the left of the o.
20. Once you've successfully added this channel, save your file.
21. Proceed to program the next by clicking on the A2 (beneath A1) and
following the above steps from step 9. Of course at step 11, you'll be
looking for A2 for the 2nd channel etc.
22. Once you've had enough, you can save the file.
23. To write your programming to the radio, choose the Transfer menu and
then select Write to radio.
24. Read the status area with the JAWS cursor. It may take about 30 seconds
to write the data to the radio.
25. Once written, and you see the "Port Closed" message, you can disconnect
your radio from the cable.
26. Turn the radio off and then on and all of your new channels should be
available in MR mode.
27. Don't forget to save your file in the software because if you made any
mistakes or wish to change any of the channels, it is much easier to modify
your file than to start from scratch. I am totally blind and it took me
about 90 minutes to program my radio from scratch, having never seen the
software before.
28. If you wish to do more programming, simply connect your radio again,
open the saved file, and continue where you left off. Don't forget to save
your work and write to radio using the Transfer menu to store your
modifications.
Note: To move to the next/prior page of channels, use Page Down/Up. After
A128 you'll find B1 through B128. Interestingly, I did not program   any of
the channels in the B group so they automatically inherited my A group
channel values. I assume you can program both groups independently but since
a blind person can't tell which one is active, it is probably safer to just
use one group and allow the other band to inherit the same values.
In my case, I used the first 8 channels for 2 meter repeaters, the next 8
for 70 cm repeaters and then added a couple of simplex channels.

Scanning
To scan, either from VFO or channel mode, press Menu, press 1, you'll hear
"Scan", then press Menu again. Scanning will continue until you press either
Menu or Exit. Note you may need sighted assistance if you wish to change the
Scan mode. 

Scanning has three modes:
* CO Mode (Carier Operated): Scanning stops when a carrier is received and
continues when it drops.
* TO Mode (Time Operated): Scanning  stops when a carrier is received and
then continues a few seconds later, even if the carrier is not dropped.
* SE Mode (Stop and Exit): Scanning stops when a carrier is received and
scanning is cancelled until you manually start it again.

Note: If you scan in VFO mode, the radio will scan all frequencies in the
current band (either VHF or UHF) by the step size programmed. If in channel
memory mode, the radio will scan through all channels. Once the radio has
reached the end of the band or channels, it will start again. 
 
Menu Shortcuts
When you press the Menu key, you can use the keypad to jump to 12 of the
most common options. Note you'll need to pres Menu again to actually select
that option to change its value. The shortcuts are as follows:
1 Scan,
2 Priority Transmit,
3 VOX,
4 Power,
5 Squelch,
6 D Wait (Dual band mode) (i.e. monitor  both A band and B subband for a
signal)
7 Auto Light,
8 Display Color,
9 Beep,
* Code"  (to set CTCSS/DCS),
0 ID Code,
# Shift (for a frequency shift),
VFO/MR/Exit Store Channel.

For example, to change the squelch setting:
1. Press Menu.
2. Press 5, the radio will say "Squelch".
3. Press Menu to select the option.
4. Use up/down to choose the value.
5. Press Menu to save the value.
6. Press Exit twice to exit the Menu system.

Hi All,

 

I'll do an audio of this one when I get time but besides the CTCSS/DCS setup
which must either be done via programming or with sighted assistance, the
rest is quite reasonable. One of our reputable ham sellers here in
Australia, Andrews Communications, says that its performance is probably the
best ever out of China. See http://www.andrewscom.com.au/amateur-radio.

I managed to program it completely using JAWS but it wasn't what I'd call
easy.

 

The reason I don't sign off with my callsign yet is because I'm waiting for
it. I've been a CB user for many years. My son and I just sat our foundation
exams and are awaiting our licenses. 

 

BTW, I have been successful in getting Uniden to make their handheld UHF CBs
accessible here in Australia. See http://wwww.criticalcommunications.com/ a
site set up by my son. I have an audio and text review of a couple of their
100% accessible models, no they don't speak but like the TH-f6a, beeps are
properly thought out. While these are only legal in Australia and New
Zealand, it should be easy to port their new firmware to new models. So, ask
and keep on asking, write to them, call them until you get a response. I did
and within 4 months I had an accessible radio in my hand. They are a company
worth supporting! If only they made amateur handhelds.
