You will see a T on the screen of tone is enabled. SHORT PRESS again - toggle tone, tone sq, dcs, and off.SHORT PRESS one time - set the tone frequency.SHORT PRESS while in the offset freq or toggle to save.LONG PRESS again - the second time you long press you toggle between -,+, and none.LONG PRESS one time - you will see the offset frequency amount.This quick guide should help to program directly. Take care in not transmitting out of band. Out of the box the unit goes below and above the legal 1.25 ham radio band. Some units have been prone to internal speaker failure due to cold solder joint or related issue. We have taken the time to document the most important programming procedures here and verified them to be correct.
#How to switch vfo mode on tyt uv8000e manual
The manual is inaccurate and nearly useless for programming. This thing is a to program from the unit! It is probably a lot easier to program with software.
The two biggest criticisms of the TYT TH-9000D are the lack of a cooling fan, and even more significantly, the painfully non-intuitive programming. Some wise ham operators have added a cooling fan on the back of the unit using a PC CPU cooling fan or something similar, especially when used as a base station. The manufacture should have equipped it with a rear cooling fan, but they did not. However, it will get very hot when operating on high power, or long QSOs on medium power. There is even a menu option to disable the VFO for channel restricted use. This is a solid built and rugged transceiver.
