Added new HAM TV frequencies, these are now supported:
- HAM TV Channels: 421.25, 426.25, 427.25, 434.00, 434.20, 434.25, 434.30 and 439.25
The correct setting for NTSC is system BG. We have changed latest firmware so there
are now different selections, not system BG and system L as before but instead
NTSC/PAL and SECAM. It is now much less confusing for the user.
Request for NTSC setting was handled via e-mail, forgot to reply to a post here as well, sorry.
You should set it to System BG. And sound carrier I believe is 4.5MHz for NTSC.
For PAL set sound carrier to 5.5MHz.
All changes effective immediately and are incorporated today.

One of the HAM ATV (radioamateur television) channels was programmed wrong,
fixed that in firmware.

Re: UHF TV update
have purchased your TV max 3000 +4 watts tested it but i can not change to NTSC, when i changed the TV satndard it say B/G and L configures to PAL, how can i change it to NTSC? i tried all the buttons in the TV standard menu but i can not change to NTSC. Need your big help.
Set it to B/G and make sure you have your video source set to NTSC and it will work.
B/G is for PAL and NTSC.
L is for Secam.
However if your video source is PAL it will not be possible to transmit NTSC,
the transmitter cannot convert from one standard to the other.

You can't download firmware.
Also it would not bring you any new features if you could.
