hi all
i am thinking about buying one of these
http://www.ebay.co.uk/itm/80MHz-108...026?pt=LH_DefaultDomain_0&hash=item19f659b6c2
how stable would it be
and what is the component called that i have ringed in the pick
cheers

 

Hello,

The ringed part is a coil with a copper core for tuning.

The transmitter will not be that stable as it looks like a free running oscillator using ceramic capacitors.

i understand the coil
but does it have a name for it as i can not find any on ebay?
makes me think it has another name

 

Everything will cause that thing to drift; battery voltage changing, temperature changing, hand-capacitance, phase of the moon, etc. It is a toy...

 

Hello,

There are some brands of those kind of coils.
Neosid and toko are two of them.

The coil in this german add looks a bit like the one you show:
