For example, if your frequency is 144 MHz then a full wavelength in air would be 300/144 = 2.08 meters. Multiplying by the velocity fac-tor of 80% gives 1.67 meters.There is also some good advice in the comments section. We note that magnetic loop antenna seem to work fairly well with the RTL-SDR in V3 in direct sampling mode, but you may need to filter out the broadcast AM band to avoid overload if the loop doesn't do this already.

The RTL-SDR is an ultra cheap software defined radio based on DVB-T TV tuners with RTL2832U chips.The signal that goes to the antenna is in the analog domain, no matter what type of (digital) modulation you use. 2FSK is a constant envelope signal, simply put, a sinewave that shifts in frequency. If you are transmitting with 20W into a 50 Ohm load your SWR-meter would ideally show you 20W FWD, 0W REV and a SWR of 1.

RSP1A covered the group of channels around 123MHz and RTL-SDR took care of the Tower on 134MHz. See the following figure: We set the bandwidth of RSP1A to 5MHz which gave us 14-bit sampling precision (better audio quality). We limited the bandwidth of RTL-SDR and put the center frequency the same as the frequency of the Tower (134.55MHz).Southwestern Randolph Middle School · October 3, 2021 · October 3, 2021 ·The hardware the (tr)USDX is running on is very limited, and it is a miracle how the developers succeeded to make it SSB capable with a piece of software even if the hardware is so weak.
