Kamikaze,

I've just started palying with these RF modules too and might have some info that may help you.

I found that reception was very flakey when using serout instructions, fortunately I use 16F628 chips that have a built in USART. ie use the HSEROUT/HSERIN instructions.

Straight away i found a marked improvement.

The other thing I noticed, was that if the TX/RX modules are too close, ie less than a couple of inches, the RX module just doesn't work.

I have been able to get good range up to 30m indoors without using any antennas at all.

I haven't yet experimented with the max range but sure it will improve when an antenna is added.

BTW I have had no problems with 4800 baud or lower. Lately I have been playing with manchester codeing, which should be used for RF data... but still trying to get that to work. See code examples.

Cheers
