PROBLEMS:
My VX7 resets or goes back to VFO mode immediately when I try to write!
OR
I added memory information to the included default.vx7 file, and it will
not write to the VX7!

SOLUTION:
The config info in the VX7 does not match what is in the file being sent.

Goto Advanced > Mods
Check Enable Mods.
Read from the VX7. It does not matter what is in the VX7.
Open the file you want to write, and write it to the VX7.

Enabling mods does not actually apply any mods. It only allows your file
config to be changed, based on the last successful read or write to your VX7.




PROBLEM:
I can read from the VX7 just fine, but I cannot write data that I read back to the VX7! Or
The write seems to go OK at first (CLONE RX for a while), but you eventually get a CLONE ERROR.

SOLUTION:
On a very few PCs, the software routine that writes to the VX7 is executing too fast, and 
the VX7 cannot receive the data quick enough. I think this happens mostly on XP. 

To slow it down:

Go To Settings > Port.
Click the "!" button. This will display the "Write Delay" dialog.

The default value is 15. Try higher values to make the write take a little longer (17,20,25).
Increase the value a little, and try to write to the VX7 again.
Very high values will cause corruption or a clone error. However, the VX7 seems very tolerant 
of slower write times.


PROBLEM:
I cannot read from the VX7, no data is received in the status window!

SOLUTION:
If you do not see any response data, then you likely have one of the following problems:

Your cable has a bad connection. Be sure it is FIRMLY plugged into the PC.

Your adapter or CT-91 has a bad connection. Be sure these are FIRMLY connected.

The CT-91 must be SCREWED IN to the VX7 all the way.

Be sure you are using an 1/8" to 3/32" adapter (such as Radio Shack - Catalog# 274-373). 
This plugs into the SMALLER jack in the Yaesu CT-91 speaker/mic adapter cable. 

You should NOT use the 3 to 4 conductor adapter that comes with the ADMS cable with the 
CT-91 and 1/8" to 3/32" adapter. 
This should only be used when it is ground down, INSTEAD of the CT-91.

If you are using a modified ADMS adapter instead of the CT-91, it is likely not
"ground down" thin enough to allow a good connection.

It is possible you may have a bad cable, adapter, or CT-91. If you purchased your cable 
from RT Systems, read the help on their website and use hyperterminal to test your cable.

Your port setting in VX7 Commander is not the one the cable is connected to.
This can be set under Settings > Port. Normally this would cause an error though...




PROBLEM:
I have tried to read from the VX7 many times, but I always get an "Invalid
Checksum"!

SOLUTION:
Double check to be sure all of your connections are good.

Try a "Set Mode Reset": Hold down [BAND]+[V/M] and power on the VX7. Then, press the 
[MON F] key.

Try a Microprocessor Reset: Hold down [4]+[BAND]+[V/M] and power on the VX7. Then, press 
the [MON F] key.

Try it on another computer. 
If it does work on the other computer, you may have an issue with your COM port hardware on 
the problem computer.
If it does not work on the other computer, then something is bad between the VX7 and the PC 
(Cable, adapter, etc)

Icom-based two transistor designs may work on some PCs but not on others due to
differences in COM port hardware. If this is a problem for you, build the 
six-transistor design here: 
http://www.icongrp.com/~sllewd/pcware.htm
or purchase a commercially made cable.



PROBLEM:
I encounter the error: "Variable uses Automation type non supported in Visual 
Basic" when trying to use VX7 Commander!

SOLUTION:
Run the included Reg_Xp.exe file. Click "Uninstall" then click "Install".

If VX7 Commander still does not work:

Download the "OLE Automation Update" from here:
http://www.qsl.net/kc8unj/OLE_Update.zip

Unzip it, and install.



PROBLEM:
I receive an error "First Block Too Long" when trying to read from the VX7! 
Every byte in the first block has a "zero byte" after it, such as "0A 00 01 00 02 00 06 00 09 
00 24 00 E3 00 03 00 02 00 24 00"

SOLUTION:
Under Win9X/XP, go into your device manager. Select your COM port, and remove it. Then, re-boot 
and let windows detect it and re-install the driver.
Under WinNT/2K, you may need to manually remove and reinstall the COM port.



PROBLEM:
I encounter errors trying to use VX7 Commander with my USB to serial adapter!

SOLUTION:
Try going into device manager, COM port settings, advanced. Slide both FIFO Buffer sliders all the 
way to the left.

Try another USB to Serial adapter. The following model has been reported to work with VX7 Commander:

Manufacturer: Belkin
Model#: F5U109
Cost: 29.99
Where: Circuit City (in the PDA section)
Settings: default Com setting, except for FIFO buffers turned all down)
