[chirp_users] Setting offset between Tx & Rx
In Chirp, how could I set a Rx frequency of 444.525 and a Tx frequency of 449.525?

It depends on the radio being programmed. If the radio supports "split" you can directly enter the TX frequency by setting the Duplex field to "split" and enter the direct TX frequency in the Offset field.
Frequency: 444.525000 Duplex: split Offset: 449.525
Then by doing anything the refreshes the spreadsheet style memory editor (clicking on the [Refresh] button for example), CHIRP will update the settings to the following.
Frequency: 444.525000 Duplex: + Offset: 5.000000
You obviously could have just entered the second method directly (after calculating the "offset" and determining the "shift direction".
See section 6.3 "CHIRP Programming Examples" on the miklor.com website's CHIRP pages. https://www.miklor.com/COM/UV_CHIRP.php#guides

Super! Thank you for the explanation. I will look into this.
I think that I am right in saying a positive offset results in a Tx Frequency above the Rx frequency.
