433 tx/rx modules usually have some minimalist antenna on their PCB. Additionally a 12m wireless link is peanuts for most UHF work, as these cheap receivers are in fact quite sensitive. Suggest you try longer ranges, with 50-100m thru' light obstructions a more typical range test. Line of sight (LOS) most can readily cover 200m-500m with simple antenna.

Glad it's working & that you've no interference- other band signals can be a 433 nightmare!

Extra: Andrew "BrightSpark" has just sent me a few pix of his solar garden lamp powered DS18B20 + PICAXE-08M + cheapie 433 MHz units. Sorry- no code or schematic were sent, but the setup is no doubt akin to my 433 mentions at www.picaxe.orcon.net.nz. He's got these "triffids" scattered around his rural property, & is even able to read them via TCP/IP WiFi network he's also involved with.

Order with the 13,10 can be an issue- try 10,13 & maybe a few commas. The normal abreviations are CR (Carriage Return) & LF (Line Feed). Ensure the SERTXD "F8" screen is set for 4800bps of course!
If fact to clarify further, CR and LF are predefined SYMBOLS in the Programming Editor. Just try:

Code:
b0 = CR
b1 = LF
debug
Have a look at page 192 in Manual 2 (rev 6.6). It has keywords and pre-defined values (symbols) intermixed but a starting point.

Maybe Rev Ed could split the list into real program keywords and predefined symbols :rolleyes:
