VER-70: Mass production version, has mass production of the first version of the United States regulations. 

VER-71:
1. Correction in the Air/FM/AM band on page 3/4/5 cannot press the M-plus (P) plus number key Memory radio station (only press the M-ENTER key memory)
2. Cancellation in the info screen displayed by RSSI at the same time as SNR
3. Correction In SW page selection out time (not confirmed), 100k at rotary tuning (normal 1k/5k, slow/fast)
4. Corrections In ATS execution, the bet bandwidth key will be interrupted
5. Fix Store SW/MW/LW at LSB/USB xxxx.5 to xxx.9 kHz, save it and call it back, and it will display 1kHz more 

VER-72
1. Fix Store SW/MW/LW at LSB/USB xxxx.5 to xxxx.9 kHz, after storage, bet SW key to call meter band, and then bet SW key to cancel meter band, which will display 1kHz more, while slow/fast/pause LCD icon will not display the problem point
2. When correcting SW band LSB/USB, xxxx.5 to xxxx.9 bet enter key and encoder down, tuning radio station (quick pick 100kHz), it will display more than 1kHz problem points
3. Correction The frequency of an on-the-machine occurrence (FM band) occurs outside the 64.0 to 108MHz range when the FM band rotates quickly on the encoder station) 

VER-73: Shipping
When being used for FM band fast rotation encoder selection, an on-the-machine condition occurs (FM band) frequency is outside the 64.0 to 108MHz range)
