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.

BIG and MAJOR update of the manual.

We have also changed the format of the manual itself.

Any feedback will be extremely valuable, please let us know how you like it.

Note we have also added new VHF TV omni-directional antenna!

Also added TV MAX for low VHF range and low power no-tune UHF version.

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.
