User manual YAESU FC-20

[. . . ] The FC-20 includes a cooling fan to ensure thermal stability of the critical matching elements within its compact case. [. . . ] On the HF and 50 MHz bands the impedance matching range is from 16. 5 to 150 (up to 3:1 SWR). Accordingly, the FC-20 should not be expected to match "long wire" type antennas unless you have taken specific design steps to ensure that the impedance presented to the FC-20 is within these specifications. Please refer to the FT-897 Operating Manual for operating instructions. Various setting By changing the configuration of an internal DIP switch, you may change the RF signal path (to enable the FC30 both on receive and transmit), and you may also clear all the tuner's memories. Remove the 6 screws affixing the case of the FC30, then remove the case. H Do not place any objects next to the ventilator ducts on the FC-20, especially those in the front.
