HAM UHF Simplex Frequencies for Intra-NET Use

With the increased number of hams in NET, the Radio Training Liaisons (RTLs) have received a number of questions on using amateur VHF or UHF frequencies for intra-­team comm to complement the FRS/GMRS channels. Teams are concerned about potential unwanted interference on FRS/GMRS due to the large number of radios in the community. Basically the NET AROs are all asking, “Which frequencies should we use?” We coordinated with Multnomah County Amateur Radio Emergency Service (MCARES) to add this template of UHF frequencies to the MCARES 2021 Radio Frequency template. To see the most current MCARES Radio Frequency Templates visit https://www.multnomahares.org/resources/frequency-lists-and-radio-programming-templates/

For VHF there are 18 coordinated simplex frequencies. Currently all are assigned which now includes 12 NET TAC frequencies, previously we had only 3 NET TAC frequencies. Typically, there are two or three agencies subscribing to each channel.

 

The RTLs have discussed the topic and concluded that UHF is the best choice. Below is the PBEM-approved template which assigns 21 simplex UHF frequencies to NET use. Basically a NET team uses the same FRS/GMRS and UHF “channels.” ­ For example, a team using FRS/GMRS channel 4 would use UHF frequency 431.450 MHz, a team using FRS/GMRS channel 7 would use 431.5250 MHz, See full list below.
