Here is the info you require.



Remove the bottom cover of the rig. 
Next to the battery there are six solder  pads,  numbered  1  to  6,  
pad  1  is already shorted (with a chip resistor)

Simply short pads 2 and 3, also check that pad 6 has a chip resistor on it,
if it has REMOVE it (if this is not removed the radio will not go out of 
band on HF and 6metres).

Replace bottom cover, then hold FAST & LOCK buttons whilst turning the 
radio on, this resets the micro-processor, you WILL lose any already stored
memories.
The Rig will now operate out of band!

TX coverage is
1.8Mhz to 76MHz NO GAPS 

****(WARNING WARNING DO NOT TRANSMIT BETWEEN 31 TO 36MHz AS THIS COULD
    BLOW THE P.A. STAGE DUE TO LOW PASS FILTER CUT OFF ! ******)

TX coverage continues on 137MHz to 174MHz and 410MHz to 470MHz

One problem that happens after the mod is the AUTOMATIC REPEATER MODE
no longer functions but repeater shift still works.

What really appears to happen is the Auto repeater mode gets set to 
USA spec.

To recap then here is the pad info

Pad 1 is short
Pad 2 is short
Pad 3 is short 
Pad 4 is open
Pad 5 is short
Pad 6 is open

I  Hope  this  helps,  Remember  that  transmitting  out  of  band and on a
frequency you are not licenced for is an offence!

One other annoying problem is the fan that is running continously,
This can be changed by connecting the fan to the PA fan, which, under
rx mode has the fan running at a much slower and quieter speed, but
at tx the fan runs as normal.
So you are not actually stopping the rx fan, just slowing it down,
which basically lowwers the air flow, but still circulates the air
during rx.

73 for now....Mark
