HYS TC UV-55

Cena rozhodně pod 200 USD stejně jako UV-66.
45W na 2m a 20W na 70cm je docela dost...

CALLING FREQUENCIES
HF To 6M -- DX, DXpedition, SSB, CW, AM, FM, RTTY, SSTV
Note: By tradition, 20M and up is Upper Sideband, 40M and below is Lower Sideband. An exception is the new 60M Ham Band -- use USB. This protocol came about as a matter of convenience in early SSB transceiver design and has remained to this day. And yes - you can operate either sideband legally where phone is allowed. And yes you can operate CW on the phone bands -- but best stay with the protocols. See URL:
