Following the recent threads on handheld VHFs, I bought myself a Standard Horizon HX270S, which I took out on the boat for the first time last evening. It works fine, but I am getting interference on some channels. The interference takes the form of a short burst of static every second or so, and is worse on some channels than others - 16 is particularly bad, but 12 (and others) are fine.
I discovered that if I turned off my nav instrument, a B&G Network Quad, then the interference disappears, and I am pretty sure that the interference is cause by he depth sounder part of the Quad. When the Quad is working, you can hear a quiet click every second or so, which, according to the B&G website, is..
“…perfectly normal and indicates that the unit is functioning correctly. Within the display, there is a powerful transformer that increases the transducer voltage to the levels necessary to fire a depth pulse. It is this particular component that you can hear.”
I am guessing that this pulse is generating a radio signal, which the HX270S picks up as static, but that it only happens on those channels of the HX270S which are operating on a frequency close to that of the radio signal generated.
Am I on the right lines? And if so, what can I do to prevent this interference?
Thanks very much
