Handheld radios can receive but won't transmit

[Tommatwalker]

Hi guys, great forum.

I've got a couple of handheld radios recently off ebay and they seem to be able to receive clearly but not transmit anything. When I press the transmit button both radios go silent (static stops) and I can transmit from the CB radio in my defender but when I transmit from the handheld radio I receive nothing at the other end. Can anyone suggest a way to test the microphones on the handheld radios?

Thanks in advance

Tom

What model radios are they , They may be different frequencies .

Hi Mate,

They are some old radios from RadioShack, I'm not sure exactly what frequency they are on (the back of the radio lists 27Mhz) but the person I bought them off thought they were channel 7 and when I set the radio in the land rover to channel 7 I can transmit to the handheld radios but I can't seem to broadcast anything from them.

Thanks

Tom

Do they say Uk 27/81 on them or do they say FCC . If FCC then they may be American frequency , Mid Band and could be AM rather than FM. Try your landy radio on EU channel 7 .

They say 27/94 on them, I believe that the radio in my landy is on the EU frequencies but I'll check.

Hi..i am a new user here. As per my knowledge you may simply have a shorted antenna connector or a bad antenna. You need at least a VHF SWR meter (cheap) or better than that an "antenna analyzer" (expensive) to test an antenna. THe radio may be fine -- modern radios protect themselves and won't transmit into a high SWR.

27/94 could be midband radios try them on the am freq but with fm modulation
