[amsat-bb] really strange RX

I cannot identify what it was that I just heard:
at 20:55, i was bringing my dial up to try and hear IO-26, but I was startled when I came accross another signal several hundred KHz below my destination! I stopped to see if it was juse local noise, and found that it was indeed LEO in origin. I picked it up at about 435.801MHz while rotating the beam from the north to my east. As far as I can tell, there is no satellite using a frequency in that range, on the list found on the AMSAT website under "Satellite Frequencies". The signal seemed to be strongest in the direction of IO26/KO25. judging by the rate of doppler-shift it must probably be either one of those satellites. It also faded out just before IO26/KO25 were near my horizon, given the inaccuracy of my PC clock, they might have been exactly at the horizon. It's been a week since I synchronised my clock, it was 4 seconds behind.
The signal sounded exactly like AO-16 MBL mode before they put it in voice mode. I think I even heard a packet or some form of data transmitted once during this pass.
Is it just a typo where IO26 is actually lower in frequency by about 60KHz? Might it somehow have drifted that far down? Or is it another satellite altogether?
