I have been asked to post information on how you can modify the Midland G9 PMR Radio to output at 5W and open up the Euro/UK LDP Channels. Currently the G9 PMR Radio is hard to find in the UK. These radios are perfect for family trips camping, walking etc. Once you have modified them the range between 2 5W handsets can be as much as 20 miles in open air.
Please note the legal maximum power of any PMR radio is 500mw as such this modification is for testing only, and will only transmit at the full 5W when the boost PTT button is pressed.
The modified version gives 5W of power when the boost button is pressed (under the PTT button) and provides 500mw when the PTT is used.
The same applies to both PMR and the LDP Band as the unit (once modded) is dual band.
Aerial is about 12cm long fixed. Feels very rugged, all the parts are sealed with a rubber grommet.
Takes 4 AA batteries (1800mah GP Batteries are included), the desktop charger is included. But as it a continuous charger is pretty pointless unless you want to kill you batteries. I use 2500mah batteries and charge them with a Maha MHC9000 charger which i use for my camera batteries and flash batteries.
A belt clip is included as well. Has lots of functions, half of which i wont use! I have the manuals and circuit diagrams etc as PDF files, please request these via PM.
OK the mod, i take no responsibility for this especially if the UK and EURO PCB’s are different (unlikely) My radios were bought done from the Netherlands.
You need to un screw the 5 screws that hold the back down,
Watch out for the battery clip as the pin will fall out.
Watch out for the battery wires they are short and connect to the back so be careful when removing the back. You can see how well the unit is now, as the seal runs around the top half of the case and clips under the aerial.
OK heres the mod,
You need a small hot soldering iron and a steady hand!
If you have any questions please let me know, or need the manual or wiring diagram etc, if you have a specific question please ask.
