Yaesu VX-7R Mods

———- Transmit Mod VX7 ——————————————————————————————————————
Remove the battery pack.

Remove the sticker/cover seal for the pressure sensing unit (SU-1), in the battery compartment. This is the black strip above cellular warning label and is where the SU-1 option goes.

Locate row of eight jumpers. They are numbered.

For Mars/Cap, remove solder jumper 5.

For Freeband, remove solder jumper 4 and 5.

Reset microprocessor. (Press and hold in the 4, band, and v/m keys while turning the radio on.

You can do all of this or you can do a soft-mod using VX-7 Commander which can be found at KC8UNJ.com. It’s free software and all you need is a programming cable and adapter. This is the route that I took when modifying my VX-7 since it is extremely easy to do, and just as easy to return the radio to it’s original state.
If something should happen to KC8UNJ’s server here are the files on my server.

—————————————————————————————————————————————————————————-——- Free Band Mod VX7 (Europe)—————————————————————————————————
If you have a vx-7 europe version here is how to modify.

Remove the battery pack.

Remove the sticker/cover seal for the pressure sensing unit (SU-1), in the battery compartment. This is the black strip above cellular warning label and is where the SU-1 option goes.

Locate row of eight jumpers. They are numbered.

For Freeband, remove(Unsolder) all solder jumper exept 3

Reset the transceiver by holding down MON/F + HM/RV + Internet Key and power up the transceiver
This will display the Vertex Standard logo instead of Yaesu. Bear in mind that resetting the transceiver by holding down 4 + BAND + V/M and powering up the transceiver WONT work!

TX Frequencies:
Freeband: 40-224.995Mhz and 300-579.995Mhz

—————————————————————————————————————————————————————————-——- Another European VX-7 TX MOD ———————————————————————————————-
I own the B1 European version (Label outside the box indicates DST:EXP / TYP:B1). Prior to any modifications the transceivers jumpers was soldered on positions 2,4,5,7 (factory setting) and the unit was capable of working on the following frequencies ONLY!

50-52MHz (RX ONLY, NO TX Possible!)
144-146MHz (RX/TX)
430-440MHz (RX/TX) Reception was NOT possible anywhere outside these limits!

In order to modify it you should:

Unsolder every jumper

Reset the transceiver by holding down MON/F + HM/RV + Internet Key and power up the transceiver
This will display the Vertex Standard logo instead of Yaesu. Bear in mind that resetting the transceiver by holding down 4 + BAND + V/M and powering up the transceiver WONT work! It will just enter a curious set up:

RX on all bands

No WX Channels

Menu Item Misc Setup 20: BEAT SQL (Instead of WX Alert)

Menu Item Special Memory 6: JR (Instead of Marine)

Menu Item Misc Setup 17: Japanese (Instead of English)

Transmittion on 50-54MHz, 137-174MHz, 420-470MHz
After the aforementioned modification you will have continues RX coverage from 504KHz up to 999MHz (including analogue cellular frequencies – NO GAPS!)
