Last night I took a UV5R to work to try and listen to the international space station transmissions.
I switched on just before it was due to pass and 446:007 PMR, close in frequency to channel 1 had two blokes chatting about cb radio etc, loud and clear.
Which was pretty good since I was hemmed in between some pretty high metal clad buildings.
On to the space station, unfortunately nothing was heard. (Maybe I should account for Doppler shift)

Later on 446:007 another bloke could be heard but not his contact.
Today I decided to finally look at programming channels for PMR at least.
For anyone wanting to set channels.
I set the frequency steps in menu (number 1 "step") at
6.25k to get the desired PMR channel 1 frequency of 446 00625 and the correct frequency steps to following channels.
Set the vfo/mr button to frequency mode.
And the A/B button to A/top frequency highlighted.
Type in the frequency you require to save.
Eg 446:00625 for channel 1.
Press Menu, scroll to or key in (number 27, "mem-ch") , press menu again, key channel number, eg- 1 and press menu again to save.
If a channel is already stored. Go up in menu from number 27 mem-ch to 28
del-ch and press, menu, channel number, and menu again to confirm delete.
I went through the 16 stored channels and deleted them all before adding PMR to save going back and forth.
So I now have the 16 PMR channels saved into one UV5R and the ISS on 145:800 on channel 17.
