I've received lots of questions about this radio. I finally picked one up and found that the Extended TX mod on this radio is exactly the same as the VX-170 mod. The procedure is posted below.
Please note that it is not illegal to modify a radio to transmit on other frequencies. However it is illegal to transmit on a frequency that you are not licensed for or that your radio is no Type Accepted for by the FCC. ThePrepared.com and it's owners are not responsible for the use of this mod nor damage done performing it.
This is a very simple mod that anyone with decent soldering skills should be able to perform. It only requires the removal of a resistor and a factory reset of the radio afterward.
Start by removing the battery from the back of the radio
Remove the adhesive cover that sits to the left. Don't worry it will stick right back on when you are done.
Locate the resistor show in the images below.
Use some solder removal braid to remove the solder from both sides.
Apply the soldering iron to the side of the resistor with slight pressure until it slides off. Be careful not to lose the resistor.
Reassemble the radio
Hold the PTT and lamp buttons at the same time and power the radio on while doing so. The LCD will display SETRST.
Rotate the dial knob to ALLRST and press F on the keypad. Please note that this will erase all the memory settings you have save in the radio.
Your radio is now modified, please be careful when entering frequencies into the radio that you normally just scan as the radio is now capable of transmitting on them. I recommend programming an offset frequency that is back in the Ham Band to avoid accidents.

If you are uncomfortable doing this mod on your own I can provide the service to you for $20 plus shipping both ways. I can be contacted at
Please use [VX-170 MOD] as the subject.
Glock 21 Torture Test
ThePrepared Gear Review: Glock 21 .45acp (Performed by Bigbore of Adco Firearms)
For almost 10 years I’ve been abusing and neglecting my Glock 21. Its been a running joke among some friends and I. Nothing was planned or documented. As I tell people what it has been through, most simply don’t believe me. I guess I wouldn’t either. If someone told you their Glock has at least 150K rounds through it and has gone almost 15K rounds with no cleaning or maintenance would you believe them?
