Hello all,
I know several threads have discussed issues with using mobile radios (such as the Maxtrac/Radius) for repeater usage because of their designed duty cycle.
Besides adding forced air cooling with fans, has anyone tired extending the cooling fins with aluminum using a thermal adhesive such as Artic Silver adhesive? It would seem that it would help with having more thermal mass and surface area.
On a side question, at least on the Maxtrac, is that the only issue with longer duty cycles is the PA and heat? In other words, there are no other components that would be the limiting factor? (ya I'm aware of the RX/TX algorithm the microprocess uses to lower TX power, I wondering more about heat generating components)
I was going to try and add maybe four inches to the fins and use an infared temp sensor to measure before and after.or maybe just use the hand touch method
