I want to know what the +10khz switch is on most of these export radios?? Thanks and sorry for the newbie question!
I always heard that the FCC allowed 5 freq. for remote airplanes and such back in the late 60's or early 70's ?? not sure on the actual date of this and some of the old 23 channel base and mobile radios had these channels and they were channel-3a freq. 26.995, ch.-7a-27.045, ch.11a-27.095, ch.15a-27.145, and ch.19a-27.195 your 10khz switch will take you there put your radio on ch. 19 and flip up the switch and you will be between ch.19 and ch.20 on freq.27.195 Back in the day we had some fun on these 5 freq. Hmmmmm enough said about that. Hope this is helpful for you.
... but the 10 meter repeaters usually have an offset of 10 kc......
