![]() For new gear, Icom makes a repeater module (FR5000?) that is the size of a mobile radio but can provide up to 50 W out (run it at 15W or less) for about $700 USD. 1 W to 10 W out, decent receive sensitivity, integrated controller with CWID, etc. ![]() So that leaves 70 cm as the most practical portable repeater as flat pack duplexers work just fine with the standard 5 MHz split used in 70 cm.Īs far as affordable equipment goes, if you can find them (they are difficult to find) a Motorola R1225 (not the GR1225 and not the RKR1225) is one of my favorite portable repeaters. Now for commercial application, there are itinerants out there with 5.25 MHz of separation.so a VHF portable repeater is actually doable. It works but it means you have to place two physical pieces of equipment. Now some folks have done split site VHF repeaters using two crossband (uni-directional) repeaters where 2 m RX is connected to a 70 cm TX and then 1/8th of a mile away or so 70 cm RX connected to 2 m TX. VHF is typically more difficult to accomplish for amateur purposes at least due to the fact flat pack mobile duplexers need 5+ MHz of frequency separation.
