Hotspot Operating Frequency
 
When hotspots are delivered, they are programmed with a test frequency. The most common are 434.0 and 436.0 MHz.
 
Unfortunately, depending on where you are located, these frequencies may be causing interference to local repeaters and satellite channels.
 

Interference
 
Avoid using the satellite frequencies (435.0 to 438.0 MHz) completely. Although your hotspot is only putting out 5-20mW, your 1-5W handheld is what will cause the interference.
 
 
Multiple Hotspots
 
If you currently have more than one hotspot, avoid having them on the same frequency. If both are in use at the same time, this will create a loop between them. This loop will lock up a talk group for the entire time both are active.
 
Also, if you are at a hamfest such as Hamcation or Dayton where hundreds of hotspots will be in use in a relatively close proximity, the odds of looping are greatly enhanced if on the same frequency.
 
 
Frequency Coordination
 
Check with your local frequency coordination group. The ARRL has a recommended Band Plan, but your local coordination group has the specifics for your area.
 
 
Eastern Pennsylvania
 
The frequencies designated for hotspot use here are:

446.525 446.550 440.925 440.950 440.975 441.000 441.025 441.050 441.075

But your area may vary.
