I ended up just browsing using the tuner to find the various channels. Just start at 1 and go up to 63 writing down what you find. This is made easier by the watermarks that all channels feel they need to impose on us???

I am running a UK unit so my RF channel is probably 22 (which is the UHF frequency that I am using to view output, as the default 60 clashes with Prime where I live).
