Hi all! Beg my pardon for my low English 
.
I have some issues with Arduino UNO and radio module NRF24L01 (with external antenna).
I have Arduino 1.0.5 IDE on my PC, Arduino replics/clones and NRF24L01 from China (arduino UNO R3 from BAITE, "classical" Arduino UNO clone, Arduino Leonardo clone). Also I worked in place without great electromagnetic pulses (Drills/mills, DC motors, welders, electric lines 600V etc. )
I worked with maniacbug version of library downloaded from GitHub.
I opened "Getting Started" sketch from NRF24 library, wired my duinos and modules as described in Intrnet or commented at text of sketch, upload sketches to pair of my duinos...
All goes fine without errors at first time...
So my problem was on screensots below.
On Arduino Leonardo it works well, changes role when R or T pressed (at COM monitor window). But I have 1 Leonardo. 
On all Uno's it writes "unknown characters" as depicted on screenshot. It's really no human language... 
Both of modules wired to my Leonardo works, at least pressed R or T changed their role.
So Uno+Leonardo and UNO+UNO doesn't work via radio...
I am disappointed by that.
Can You help me or have some suggestions about my problem?
P.S.: I do not solder any capacitor between 3.3v & GND on NRF24 modules(them was "as from box").
All modules have their power from 3.3V port on their Arduinos. Arduinos are powered both from PC via USB or 220/6v power supply.
I experimented with supply at all combinations - only bad results on UNO's achieved...
NO other sensors, buttons and so was wired to Arduinos. All NRF24 was powered from Arduino at time of uploading of sketch.
