RFM12B - Distance - How to improve distance between emonTX and EmonGLCD

Hello

Have finally managed to sort out and build all 3 modules and connect up to the PV system - all looking resonable good with the exception of the above it turned out quite a learning experience - I have to thank many of your post and the dedication of the members here for my success.

My question is how to improve the tx and rx distance between modules - simple walking away experiments suggest a line of sight of about 10 feet is the maximum or  less though a wall.  Does anyone have any tips to improve this or what can be measured or checked to confirm they are working correctly?. They are operating at 868Mhz

 Hello David, they should give much more than that, my test range here is about 30-40 feet and two thick stone walls at which point it starts to get flaky. Have you got the frequency in the sketch set to 868Mhz?

Ok I get that maybe not (in the time honered way "don't assume anything")  - too late tonight to check - will have to reload all the programs to confirm this will let you know the outcome.

Many thanks for the promt reply

sucess - most likley the emonGLCD was set as per sketch not 868Mhz - will try out distance trials later on in week

Your help appreciated
