sounds silly, but have you checked the position of the 3 way switch on the ptt...are you on "always transmit"???
 
Can't hear them

If you unplug the radio from the autocom can you hear them? At least this will narrow it down to radio or autocom?

Okay , now swop bikes this will narrow down Autocom unit or helmet?

Volume ? on the radio turned down to nil ?

do you know what model of radoi's your buddy's have ?

take the radoi out of the Autocom setup and using it on it's own,, if they can hear you but you can't hear them, it sounds like you are on diffent sub-channels or CTCSS

basically PMR radios have 8 main channels and 32 sub-channel on eack main channel.

so if your on channel 3 but no sub channel and your buddys are on channel 3 but sub channel 13 then they will hear you but you won't hear them.

check the radio channels, Kenwoods have a selector switch but the numbers on the switch don't relate to the channel you on, check the manual or check the Kenwood list here
 
Right i will have to put the batt back in and i'll try of bike. my brothers radio is a cobra microtalk.tryed all postions on switch to.
 
Why can't life be simple?

Do you hear other audio sources such as navigation prompts or music. Better still do you hear yourself when you talk on the Autocom?

[edit] - Does the unit have a squelch type control. If so and you turn it right down (so least amount of filtering) then can you hear taxi/emergency services/any other traffic. Or does it have a scan option where it scans through all the channels and stops to play anything found, then keeps scanning again? Won't solve the problem but would at least let you know the unit works.

Oh and can you hear anything through the radio when it is off the bike?
 
Set your mate's Cobra to channel 1 and use CTCSS code 10. If that works have a look at the list Roddy linked to for the other common channels/codes
 
Why use ctcss at all?

Is pmr 446 that busy down south that you have to share channels?
 
As I understand it Kenwoods come with a CTCSS code for each channel by default

In my neck of the woods there are endless beeps, whirrs and other bursts of RF so CTCSS makes things much more relaxed

If you don't use the sub-codes you get every taxi driver, chinese restaurant and security officer on air this side of Bognor!

right if i press the squelch button i can hear them so where do i go fron here as i know nothing about walkie talkies:mad:
 
Normally squelch is adjustable. It sort of filters out weak signals.

Therefore if you have the squelch all the way down you should hear all sorts of crap, hiss and the like (as well as legitimate transmissions). Then as you turn the squelch up, you should lose the crappy signals and hiss and only hear strong decent transmissions and there should be no hiss or static when your mates are not transmitting.

But you say you just have a squelch button? That I don't understand.

[Edit]. Just downloaded the manual - seems this unit does not have adjustable squelch just (as you say) a squelch on or off system. If you can only hear your mates whith the monitor key held in then they must be transmitting using a very poor signal, or you have a hardware problem, or you are not using the same channel (maybe close but not exact).

Do your mates have the same radios?

[Edit #2]. Have you looked page 15 of the manual, QT and DQT - seems like that matches your problem doesn't it?
 
The Sub-codes thing isn't really hard.

The 446 radios work on 8 standard frequencies:

  • 446.00625
  • 446.01875
  • 446.03125
  • 446.04375
  • 446.05625
  • 446.06875
  • 446.08125
  • 446.09375

For the radios to talk to each other they have to be on the same frequency.

Some radios, eg the Kenwood TK**** series also have subcodes. Kenwood call the, Quiet Talk (QT) codes. These are also referred to as CTCSS codes. Some are analogue, some are digital (DQT). The purpose of these codes is to filter out unwanted signals from other transmitters using the same frequency. If either bike-to-bike radio is set to use the sub-codes, they must both be set to the same code. There are around 40 different codes.

The Kenwood is programable so to can amend the sub-codes on any preset channel. This is a case where you really do have to read the manual for both radios and ensure that not only the frequency is the same, but the sub-codes are the same too.
