    Does anyone have a copy of the technical note re: adding RF gain control or the kit?
    Info on the mods made to the VFO by Tentec on exchange?
    I read about them here: https://www.qsl.net/tentec/mods/525mods.htm

    I'm particular interested in TN2-525.

    WRT RF gain, I do not have a blanker or audio filter board. That leaves three
    front panel switches free. If I can't find the TN and/or parts, one switch can
    be adapted to switch a 20 dB pad in and out between the LPF and BPF boards.
