I have been bitten by the analog bug... 
I recently got a Toshiba TRX-80 analog receiver and will soon be getting a remote that should work for it (thanks Davage). It's currently only set to C band, and I only have a Ku band dish, but I've played around with it some and made some interesting observations. I have the Toshiba slaved to my Pansat's IF Loop Out port. I'm using the Pansat to move the dish and select the appropriate polarization.
Since analog reception is a lot more forgiving with a weak signal or improper tuning, a lot can be learned by playing with it. For instance, a receiver (analog or digital) can technically receive something from Ku band when it thinks it's receiving something from C band. LyngSat shows a couple Ku band analog test cards, one at 85°W (12175 H, tp 24) and one at 121°W (12045 V, tp 23).
My analog receiver was able to partially tune in the 85°W card by tuning to channel 1 (3720 H, tp 1). The intermediate frequency for 3720 is 1430 (5150-3720). Adding that IF to my Ku band LNB's local osciallator frequency of 10750, I get 12180... high by 5 MHz. The audio came in ok, but the video was somewhat scrambled looking like analog cable premium channels used to be. I assume it was from missing one of the sync signals (horizontal or vertical) since it was a matter of the scanlines not being correctly aligned horizontally and the colors were off. But it did have enough of the signal to sync with the frames since the picture was stable vertically.
The 121°W card was the same situation. The analog receiver found it at channel 8 (3860 V, tp 8). The IF is 5150-3860=1290, which becomes 10750+1290=12040 on Ku band, low by 5 MHz.
Soon I might get a C band LNB to put on my motorized 100cm dish to see what analog stuff I can get. I know it will look like crap without enough gain, but I should see at least something, whereas with DVB I highly doubt I'll have enough signal for a lock.
