Noaa95 HRPT board upgrades

Close pin 1 and pin 2 of U15, pin 1 and pin 2 of U18
Defalut configuration: JP1 open = addr 0x300
both S1 and S2 close to right = DMA ch 3
Close to GND the central pin of R22 (not to be mounted)
In rare case, Noaa95 card may give problems while switching on the PC.
Here is a little upgrade: a delay that will remove this inconvenient eventuality.
Description: cut the existent track between U18 pin 1 and central pin of S1.
Replace using the free port "D" of U7 wired as shown above with a capacitor and a resistor between +5 and GND.

FengYun99 c-HRPT board upgrades

Finally here are all the necessary information to modify your Noaa95 HRPT card to receive c-HRPT transmissions from FengYun satellite.
Unfortunately its signal is very weak so you need a good dish antenna and preamplifier or downconverter.
Not many components must be changed. Unlikely you can't use the same card to receive both HRPT and c-HRPT. You need 2 different cards.

Here is a complete component list CompList

As shown below, you need to change the RED capacitors C9, C65, C66, C67.
Then change the RED capacitor C62 and remove C17.
Finally, replace R29, change C54 value, mount C70 between HD-6409 pin 13 and the ground.
Substitute the pink coil with the home-maden.
