I'm getting a lot of underwater, warbly noises when listening to digital Fleetnet channels and would like to upgrade the firmware to try to improve it. I'd also like to upgrade to the rebanding firmware on the main unit. Unfortunately, the seller hadn't used the cable in quite some time and could not find it at the time of the sale.

Is there anyone around the Orillia area or the GTR that would be willing to help me flash my BC296D for a big box of Timbits? :)

I'd also be willing to buy a cable that someone isn't using anymore.

I believe I found it. I have no idea what they go for, but why don't you PM me with your details and we'll go from there.

Adjust the P25 card settings..thats probably the reason for the warbly digital noises.
And it can be done WITHOUT a cable (I find for fleetnet the sweetspot is somewhere in the 900-1000 range)

Taken from page 56 in the manual..

Setting APCO 25 Sound Quality..

Each APCO 25 system has slightly different system settings
that control how the audio is digitized. To get the best sound
quality, you need to match as closely as possible the system’s
settings.

To adjust the sound quality:
1. While monitoring a specific APCO P-25 talkgroup, press
the HOLD/MAN key.
2. Press and hold the 9 key. On Line 1 of the screen you will
see SOUND QULTY: 0050 (for example). This shows
the Sound Quality. The lower the level the better the
Sound Quality.
3. To manually set the sound quality, rotate the scroll bar up
or down. As the threshold adjusts in increments of 100 at
the bottom of the screen watch the Sound Quality level
increase or decrease and continue to rotate the scroll bar
until you have achieved the best Sound Quality level.
Notes: • When APCO P-25 signal is not received, SOUND
QULTY: **** appears on the display.
• You must be receiving an APCO P-25 signal to
make this adjustment
A chart showing the Threshold Adjustment Range is listed
below.
4. Once you have adjusted the Sound Quality to the best
possible level, press E.
Press RSM to exit the Sound Quality Adjustment Mode.
