WideBand for Yaesu 817 857 897

Widebander. This software will allow you to extended TX for the Yaesu FT 857 FT 817 FT 897 and reset back to standard factory defaults. Warining: this programs looks like not to be supported. Download and use it at your own risk.

MODS

==================================
02-01-2001  Battery mod for ft-817
==================================

Yaesu folks want you to buy the 9.6 vdc battery pack and do not recommend you attempt to charge
batts. from the included "stock" alkaline pack. They have even rigged the pack so it will not 
charge. Poking around with a VOM I discovered that there is a way to make the alkaline pack 
charge. Pull out the pack and peel the tape off of the end with the wires. You will find 2 red
wires, 2 black wires and a green wire. cut and insulate the green wire. Put Nicads or NiMh 
Batteries in the the pack and set up the charge time circut. I have done this with no problem. 
This keeps you from breaking the bank buying alkaline cells and give you portable batt. power. 
Two words of caution: 

As with all mods, the warranty is affected, do so at your own risk. 

By during this mod you have now disabled the protection feature and can re-charge alkaline 
batts. This could be dangerous and messy...be careful not to do that. Of course with this mod, 
you will have little reason to use alkaline cells. Enjoy. I look forward to hearing about other
ft-817 mods for this nifty little rig. When you do the "green wire mod" on the FT-817 to permit
charging of internal NiMH or NiCad batteries, it's very important to install fuse protection or
you could ruin your motherboard (a VERY expensive mistake). 

Perhaps the easiest way is to install a 2-3 amp Pico fuse in line with the positive (red) wires
leading to the battery pack. Better still, put another Pico fuse in line with the negative 
(green) wires also.

20-01-2001  Extended TX for FT-817
==================================

1.Remove the front panel

2.Look down on the back of front panel, with the VFO knob just left of center. Look at the 
  jumper locations just above the VFO knob on the circut board. Solder the first four jumpers 
  and remove the solder at location five.

3.Reassemble the radio, and reset the cpu by pressing the HOME and the power button.



This will extend the xmit freqs. on HF,VHF and UHF 
--------------------------------------------------------------------------------
Another mod. 
The following Yeasu FT-817 frequency expansion modification is identical to the version provided
by the manufacturer for MARS/CAP application. 

Remove any power or battery from the Radio.

Remove the 14 screws holding the top and bottom covers to the radio.

Remove the battery cover latch.

Remove the covers.

Remove the BNC retaining nut.

Carefully lift the 4 plastic tabs holding the front panel to the chassis and slightly move the 
front panel forward.

Disconnect the ribbon cable that connects the chassis and the front panel.

Remove the jumper at location on Front Panel (J4005)

Press and hold the "VFO/MR" key and the "F" key while turning on the radio.

Reassemble the radio. 
Note: The manufacturer states that "this modification opens up transmit coverage for MARS/CAP 
ONLY!" Other published modifications also have the user bridge the "first four jumpers". The 
difference between the two modification schemes has not been tested by the author. 

Proceed at your own risk.

=======================================

Just push and hold A, B and C simultaniously while putting the rig on, and you're in the hidden 
menu with about 57 settings. Number 5 for the 2 meterband will increase sensitivity while 
increasing he numbers; Default setting / 79. 

To leave the menu just push and holf the F function just as the "ignition" switch will do . 

It works...
