    Overview
    A very inexpensive, small and lightweight VHF aviation transceiver.  It is not a TSO'd unit.  It fits into a small 57mm (2 1/4") instrument hole.

    Customer Feedback
    I have heard back from several customers about this radio.  Their feedback was very positive. 

    Pros

    • Inexpensive
    • Small size
    • Lightweight
    • Simple
    • Music input jack (mono)
    • Dual Frequency Display (Easy to enter new frequency in the standby line and the use the flip/flop button to swap the active and standby frequencies.)
    • 32 Memory Channels
    • PRI button - One button press to access a primary (user programmable) frequency such as 121.5 or your home airport.

    Cons

    • Non-TSO - I think that means that it can be used in experimental aircraft, but not certificated aircraft.
    • The minimum input voltage of 11 VDC makes it questionable for use with a 12V glider battery.  However, 12V batteries normally charge to 13 or 14 V - so it may be OK.  A 14V battery is probably necessary (but I really don't like 14V systems because the 2V batteries don't last and it is difficult to find a good 14V charger.  The specifications state that the minimum voltage is 11.7 volts.  I told my dealer that 11.7 volts was a big problem for use with a glider battery and he said that the manufacturer said that it would operate down to 11 VDC.
    • High standby current of 300 mA (compared with 50 mA for a Dittel FSG 2T)
    • Does not work with dynamic microphones as supplied by Dittel, Becker, etc.  But it works well with the Peiker ME510-25in gooseneck electret microphone.
