500hd glitch

[mapex]

My hd channels are on 90ish signal strenth but the hd
glitches a lot, ordered an amp but not arrived yet. My
question is can i change or set anything on my receiver
settings to help with this.

this method reportedly working on clones with glitch issue , worth a try i guess , not tested by myself , cut+pasted from another inferior forum lol

Change tone amplitude of tuner. Telnet to your box, and enter the following command... this should show you what your box is currently on.

Code:
cat /proc/stb/frontend/0/tone_amplitude
Then to change it enter:

Code:
echo X > /proc/stb/frontend/0/tone_amplitude
Where the 'x' is, enter a value from 1 to 10... start at 1 and work your way up untill one works (if it works). Then save it to /etc/init.d/bootup so it will execute at startup.
