Congratulations! Great picture and with only a 10 dBi yagi antenna meaning an exotic antenna not necessarily required for successful receive. It would be nice if on Sutro and a 5000 watt xmitter (but a heck of an electric bill), however, I like it. No comcast interference!
Well, no comcast interference, but we can only hope the part 15 QRM stays away.
But yeah, from my house in South East Santa Clara, it didn't take much of an antenna to receive - 7 elements at 900 MHz is about a foot long.
I've modified the exciter-amp connection a bit by adding 6 dB of attenuation and adjusting the exciter power upwards to match. That will keep the exciter in a higher quality portion of its power range. Watch the blog for more details.
Is there any way this could be done using the 50-54 Mhz 6 meter band?
Does the ATSC channel have to be 6 Mhz wide?

@otakumo ATSC channels are indeed 6 MHz wide. The 6-metre and 2-metre bands are just not wide enough.

@denelson83
How about the 70 cm band?
420-450 Mhz

@otakumo Yes, that's wide enough. In the US, there are three channels in the 70 cm band allocated for ATV use.
