Baofeng walkie-talkie UV-K61wireless HAM replication frequency, 999CH, C-type, DTMF,remote, NOAA, K61, K5 (8) 50KM UHF, VHF
Aliexpress UK
Resolution: 1Hz. Frequency range: sine wave 1Hz-500kHz (where the output amplitude is flat up to 200 kHz, and the output amplitude be reduced as the frequency is further increased), other waveforms 1Hz-20kHz (but the upper limit of the adjustable frequency is not a limitation, and the use of the frequency can be further increased if the distortion and wobble are not required).
