A Little VC10derness

The comm 1 and the comm 2 on the VC-10's radio stack have four places to change the frequencies for example 12.28. How would a VC-10 contact lets say Heathrow Director on 119.725 which has six digits or generally any position with six digit frequencies? Has the RAF installed more modern Radio Stacks on the VC-10?
I am using the VC-10 C1K by David Maltby,and maybe the panel is a little out-dated.

Basically you've got 5 positions on the Comm sets, but the first '1' cannot be changed. This isn't necessary as all comm frequencies are between 108 MHz and 136 Mhz. When you've got a six digit frequency just set the first five digits in the set. So for 119.725 set 119.72 in the set and this will work fine.

Officially I'm not the helpdesk for David Maltby's Flightsim stuff. His own website is here: http://www.dmflightsim.co.uk/ and for support it's best to go to the Classic British Flightsim Forum here: http://www.cbfsim.org

Thanks for the reply,yea i'll post on his forum.
