BC125AT: BC125 off frequency

[Falcon9h]

That said, if you’re near a suitable VHF or UHF beacon then you can check the tuning without opening it up. If you’re stuck and you’re in the London/SE area then I’m happy to pop it on the bench and check the performance.

Well, that's a nice offer, but we've got the Atlantic between us! 😄 I used to have access to a service monitor, but that was 25 years ago.

When I get some time in a couple of weeks I shall set up some appropriate bench tests and quantify what happens in these situations. To be fair I rarely see much kit off-frequency very much because of the type of kit I’m using but based my comments on experience a while ago when I looked at these questions before.
