On our rides, we sometimes have bikers who can communicate using bike-bike radios. These are all PMR-446 type ones with 8 channels and 38 sub-tones. We have organised them according to the chart below and we normally use channel 7 as the "MANHOC" frequency. So, if you want to join in, just tune your radio to match the list below. Those with Kenwood radios may want to contact Alan (@manhoc.co.uk) to get channel 7 tuned in correctly.

There are lists for the Kenwood 3101, 3107 and 3207 plus the Icom 22R. Other radios should be compatible with those.

If you need a translation from CTSS number to CTSS frequency, this table should help (thanks to Tom for this).
