A 50Ω dummy load is a simple but crucial piece of test equipment. Not to perform tests on its own, but to provide a good testing environment. A common test is output power of a transmitter, or a stage within a transmitter. At QRP power levels of 5 watts or less, it becomes very...
There are only two basic steps used to optimize the operation of a simple ISM transmitter (shown in Figure 1): make sure that the reference frequency is properly tuned, and correctly match the output network of the transmitter to the antenna. A crystal oscillator is commonly used as the ref...
433mhz RF transmitter and receiver:It operates on a specific frequency of 433MHz. There are several other radio frequency devices available in the market and as compared to them the performance of an RF module will depend on several factors like when we increase the transmitter’s power a larg...

Finally getting Freelink to work I’m trying to program some S6R receivers. I’ve updated the S6R firmware to the latest and greatest, I have the latest OpenTX (2.3.11) on my transmitter. The latest Lua for the SxR. Now the problem. I can’t get the receiver (s) to bid to the...
At this point you can also go in and modify that value. It could change the upper range to something different by pressing ENTER and then go ahead and make your change. Notice down below it is showing you what the default value range are for that particular transmitter. I could go anywhe...
increasing the power of the transmitter does not help the problem; you will always be getting the same ratio. The loss of signal is due to the signal going in every direction, which results in less of it as the distance grows. What we need is a way to concentrate the signals where we...
The diodes and circuit of the trigger coil tester may resume their role as a diode in themselves if they do. Also, the end of the trigger coil, which is not connected, acts as an RF transmitter with a with a short range, which can be picked up by the ghost detector circuit. Just ...
