I managed to snag a MicroMod 2 off ebay last week for $500. It was said to have come from a store (hh greg?) but I am not sure because it was set to DVB-T when I first powered it on. At first I thought I had to move to Europe to use it, but thankfully the option to switch it to ATSC was available in the front panel menus (apparently cannot be done from the web interface). I was able to get it mostly configured from all the pointers in this thread. I have RF1 set to 797mhz (ch 68) and RF2 set to 803mhz (ch 69). After tweaking the bit rate and audio settings I am able to connect it to my whole house coax splitter-amp and re-scanning all the TVs in the house finds my two ATSC modulated channels. The only problem I have i that is does not seem to be sending the settings on the Input->Encoder Out Param page. The TVs see the channel as 68-253 and none of the Service Provider, Program Name, Short Name, etc. options seem to be sent down the wire. Can someone share their settings on how to get these populated properly?
Two caveats on the modulator now that I have it working:
1. Be very careful when hooking this up to a TV or your antenna distribution system. As mentioned somewhere in this thread, too much signal can cause damage to a TV. I managed to fry the front end of the tuner in my beloved Panny plasma when I first hooked the modulator up to my antenna system. Once it was cooked, the TV would not receive any UHF high channels. Luckily I had a spare tuner module for this TV so I was able to rip the old one out and solder the new one in, fixing the problem. I have set the power output of the modulator to -30 and added 40db of inline attenuators between the output of the modulator and the modulator in port of my whole house antenna system.
2. There is roughly a 1 second delay added to the stream as it gets encoded, send down the wire and decoded by the TV. This was never an issue with older analog NTSC modulators so be aware if you are coming over from that world. If you are using this to send out your DVR to the whole house and sending remote control signals back to your head-end, be prepared to wait 1 second to see the result of key presses on the remote.
