Hi guys,
I'm just starting out on doing some research on which radio might work best for my project, and decided to get some breakout boards for the radios (rfm69's and 12's of all flavors) solder them up and then swap in and out as needed for testing in the environments. well, i ordered some breakout boards from OSH Park

and soldered the radio's to them (the picture shows a rfm12b 915mhz) and plugged it into the breadboard, have triple checked all the wiring against the info associated with the radio and arduino hookups,

have made sure to use the 3.3v so no resistors are needed (at least as far as i can tell) and have tried running the basic send/receive sketch from the library here:
https://github.com/LowPowerLab/RFM12Bso they upload and compile properly, i change the setting in the sketch to be set for 915, and i can get the serial monitor to read out that it's sending, but the receiver doesn't seem to send the ack, so the sender won't continue to send, adn it pretty much stalls out there.
i've tried switching the programs on the two setups i have (identical) so the sender acts as the receiver and vice versa, but they both respond in the same way as mentioned above. If anyone might ahve any insight into how best to troubleshoot this, i'd appreciate the perspective. i'm at the limit of my knowledge and have tried everything i know how to do- i'm guessing that i might need some additional hardware, as all the breakout boards i see on the other sites seem to have resistors and things such as that (showing my ignorance of hardware here) plugged into the boards, and i have none. but the 3.3 volt interpretation of the sketch doesn't seem to call for them, so i'm not sure what's going on. anyhow, i'll post the picture below so you can see my rig and thanks for your help, i'll answer any questions if there's more details you need to troubleshoot. thanks a million guys and gals.
