Complete Newcomer - my OBS/CDI wont activate

Apologies in advance if I am not using the correct terminology - I am new to MSFS 2020

I have got to grips with the basics - I am trying a VOR Navigation flight in the Cessna 152, following a tutorial I watched.

I ma sat on the runway at Prestwick Airport I have entered frequency for a couple of local VOR stations - Turnberry 117.5 or Machrihanish 116.0. When I click the make frequency active button on the NAV 1 console nothing happens on the CDI/OBS instrument

Am I missing something ? I've done some reading but I cant find anything - I've looked at all the instruments on the dashboard to see if I need to activate something.

My setup

I am using MSFS 2020 via Steam version 1.21.18.0

Windows 11

AMD Ryzen 7 3800X 8-Core Processor

Nvidia Geforce 3060 Ti

16gb Ram

1 TB SSD XPG SX8200 M.2 NVME

2 TB SATA3 Hard Drive

I installed the Game via Steam to my SSD XPG SX8200 M.2 NVME

I put the packages on my other SATA3 Hard Drive

Any help would be appreciated.

It looks like you've got the wrong frequencies entered in both cases. Your text says 117.5 and 116.0, but you've entered 116.05 and 117.05.

I tried the numbers in your text and they work fine, though 116.0 didn't come alive until I was off the ground.

thanks for the reply.

it was indeed a PICNIC issue - problem in chair not in computer
