    Hi,
    I just got a Kenwood 7500G VHF transceiver and the optional external VFO. According to the VFO manual (from the internet), one should set the channel in the Trx to "VFO" in order to use the VFO. However, the Trx has 23 channels, but no "VFO" setting. When looking on the internet, I saw a Trx-VFO combination with "VFO" displayed in the channel window.
    Can it be that there are two versions of the 7200G, one with and one w/o the VFO setting?
    Thanks and 73,
    Florian OE1FLS

    Trio made a TR-7200 and a TR-7500. You mention both in your initial post. Which one do you really have?

    The TR-7200, which was designed as a mobile rig, has crystal switching for receive and transmit. Don't see how a typical VFO would work here. What is the name and model number of this VFO?

    Kenwood produced the TR-7200 and the later TR-7200G VHF FM (2-meter) transceiver
    SO, Which model did you actually purchase?

    RigPix has the Manual for the TR-7200G transceiver and Accessories.

    There were TWO (2) Kenwood Models of external VFOs,
    VFO-30 and VFO-30G (600 kHz offset added).
    Photo of VFO-30G below.

    NOTE: Circuit Wiring modifications are required to the TR-7200 transceiver.
    Found on Page 9 of the MANUAL.
    Your “TR-7200G” MAY already have these changes.

    Hi,
    thank you for your feedback!
    I got a Kenwood-7200G and a VFO-30.
    Interestingly, while the English manual of the 7200G mentions the option for an external VFO, the translated German one does not.
