The WRL 65A Globe Scout has been designed to provide the Amateur, Novice or Experienced, with a complete mobile or fixed station transmitter. Primarily designed for fixed station operation, the transmitter may be used very effectively as a mobile transmitter by the installation of a suitable dynamotor or vibrator supply to provide the necessary B plus voltages. The Pi-network in the final stage will load into any random length antenna or into a mobile whip antenna. Complete band-switching eliminates inconvenient plug-in coils. Band changing entails only the changing of a crystal (crystal socket located on front panel) or the switching of a VR1. Precautions have been taken to provide a TVI and BCI proof transmitter; a completely shielded cabinet is employed along with adequate bypassing of all external leads. The Pi-network provides a high degree of harmonic attenuation when properly tuned, eliminating the necessity of a low-pass filter in most cases.
