TH-9800 Factory Software Caution

Modified on Tue, 26 Mar 2024 at 11:50 AM

The TYT factory software can be used to expand the TX capabilities of the TH-9800 but there are some pitfalls to be aware of.

There are two versions of the TH-9800. One is 10M/6M/2M/440 and the other is 10M/6M/2M/220. The only difference is the final available band- 440 or 220. There are physical hardware differences between these two versions.

When you use the TYT factory software you can enter a frequency range that the radio is not capable of transmitting. You can send a 440 frequency range to a 220 radio and vice versa. The radio will accept this information, but it WILL NOT gain the ability to TX on a frequency that it does not have the hardware for.

If you use the TYT software to send a 440 frequency range to a 220 radio and then program a 440 frequency in to the radio’s memory you will be able to call that memory channel up on the radio but the radio will enter in to a continuous loop of beeping to indicate that it is displaying invalid data. The radio will not transmit while in this loop.

Always exercise caution when using software to modify your radio as you can cause issues like the above that can be difficult to recover from. RT Systems software does not facilitate so-called “soft modding” of any radio for any reason.
