Wireless microphones?

[Kenny Cargill]

I have an Ashton AWM200 wireless microphone receiver and it lists among
channels:
UK9 863.100
UK10 863.900
UK11 864.500
UK12 864.900
Looking at:
http://www.maplin.co.uk/p/prosound-replacement-8648mhz-mic-for-n61gf-wireless-microphone-kit-n09jl
and
http://www.maplin.co.uk/p/prosound-replacement-8638mhz-mic-for-n61gf-wireless-microphone-kit-n08jl
listed as 863.8MHz and 864.8MHz.
Will either or none work with this?
It was bought with a headset mic but would like to use it with a handheld.

First check that those frequency remain legal where you are.

They MAY work with you receiver, but there is a (remote) chance that the
system uses a pilot tone for squelch or data such as battery condition,
in which case it may not.

How about the correct Ashton mic - or no longer available ?

If you are asking will the system work with the rx and tx off from each other by 0.1 MHz or 100 kHz, the answer is, not very well if at all.

Thanks for the replies, the receiver has 16 UK channels, 9-12 legal in the
UK between 863-865MHz and 16 Australian 795-820MHZ, all legal, says the
others need to be licensed whatever that means.
It has a Mode switch which apparently switches between channel select and
variable tuning, does this mean that I can tune it like a radio to suit the
mic so long as it falls within the frequency band?
To Geoff there's a variable squelch control on the receiver, also I recently
missed out on the correct Ashton HT200 mic cheap on Ebay!
This is Australian made and the Ashton mic isn't readily available here in
Ireland.
This is for home, not commercial, use and I'm just trying to get a
reasonable priced mic to work with it.

It means that if you want to use them, you have to fill out some paperwork
and send it to the ACMA.

Maybe. I highly, highly recommend not using the variable tuning because it
is apt to drift or be knocked out of place.

It may not be legal to operate in Ireland.

The problems that you have, though, are mostly that the wireless mikes,
although they may use the same frequencies, don't always use the same
compression and modulation. So you may get audio, but it may sound weird
if the compression at the mike is different than the expansion at the
receiver, or if the emphasis equalization at the mike is different than the
de-emphasis at the receiver.

If it's just a paging appplication you could get away with it but for
proper work I'd hold out for the correct transmitter.

Here in the US, you constantly see wireless receivers on the surplus
market, often pulled out of churches and schools, but never with the
appropriate microphone. Consequently there's a big demand for used
mikes on Ebay....

As he lists a UK supplier, I assume he's in the UK or Northern Ireland,
which doesn't have the same licensing rules for radio microphones as the
USA.

For contact details and getting a licence.

http://www.pmse.co.uk/equipment/wireless-microphones-and-monitors.aspx

For information about what frequencies are legal, which are licence
free, and which need licensing either as a one off for anywhere in the
country or for a particular location and event.

The rules may differ, depending on whether he's in the ROI or Northern
Ireland.

Personally, I'd just go for a complete package from a local Maplin or
Digital Village store, as that will be guaranteed to comply with all the
legal requirements and work without problems.
