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

<pre class="moz-quote-pre" wrap="">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.
