Description
This RL Drake FF-1 Fixed Frequency Adapter Accessory Crystal 5107.00, has been checked and is working properly as tested in an FF-1
To calculate the FF-1 crystal frequency:
Band Range Formula (fd=desired frequency) 49.5 49.4-50.0 fd -44.5 = FF-1 crystal frequency 50.0 49.9-50.5 fd -45.0 = " 50.5 50.4-51.0 fd -45.5 = " 51.0 50.9-51.5 fd -46.0 = " 51.5 51.4-52.0 fd -46.5 = " 52.0 51.9-52.5 fd -47.0 = " 52.5 52.4-53.0 fd -47.5 = " 53.0 52.9-53.5 fd -48.0 = " 53.5 53.4-54.0 fd -48.5 = "
For example: Desired frequency is 50.160 MHz. Band 50.0 MHz. Subtract 45.0 MHz from 50.160 MHz and 5.160 MHz is the frequency of the crystal needed for the FF-1. Add a kHz for CW operation.
The Drake FF-1 fixed frequency adapter is disigned to work with the TR-4 series.
Has two crystal sockets. Crystals are not supplied. 8 x 0.75 x 3.5 inches. 11 ounces.
