CHIRP

Jim,

I have a UV-5R, purchased in Jan 2017. I have the offsets set in the chirp program for my presets, I select UV 5R and upload them to my radio. But when I go to MR and select the preset channel, my radio doesn't change to the proper offset frequency when transmitting. It stays in the receive frequency. It doesn't seem that chirp is calculating the offset frequency and sending it to the radio as a seperate transmit frequency.

If I go to VFO mode and set all the same things manually that I have in chirp, the radio shifts to the proper transmit freq, and transmits the proper tone (ie it works manually programmed in VFO). So this seems to be a programming error.

From what I read in your post above, Chirp should be taking the offset I put in it, and calculating the proper transmit and receive frequencies, then uploading them to the radio. Correct?

If you set he Duplex and Offset fields correctly, CHIRP calculates the required TX frequency for the memory. Select a memory where the RX and TX frequencies are different (one where "+-" is shown in the upper status display). The RX frequency will be displayed. Then tap the [*] key to put the radio in "reverse mode". The display will switch from the RX frequency to the TX frequency.

If I go to VFO mode and set all the same things manually that I have in chirp, the radio shifts to the proper transmit freq, and transmits the proper tone (ie it works manually programmed in VFO). So this seems to be a programming error.

Not a programming error. As I explained above, the radio functions differently in VFO mode.

No. CHIRP only calculates the TX frequency. You provided the RX frequency.

When Duplex is set to "-" or "+" then CHIRP uses the provided RX frequency and the provided Offset amount to calculate the TX frequency. The RX frequency and the TX frequency are what is sent to the radio because that is what it requires for each memory channel.
