Included are the following chokes and installation guidelines for three Mercury Models:

Mercury Lite - 4 Ferrite Filters

RF Input: F240 Ring – 5-9 turns of RG-8x (1/4") size through center

RF Output: FSB-1 (Big Clamp on) – 3 turns of RG-8 (1/2") size cable

Relay Cable: FSB-1/2 – multiple turns through choke – ½” diameter hole

DC Power Line: FSB-1 (Big Clamp On) – 3-6 turns through center


Mercury IIIS - 6 Ferrite Filters

RF Input: F240 Ring – 5-9 turns of RG-8X (1/4") size through center

RF Output #1: FSB-1 (Big Clamp on) – 3 turns of RG-8 (1/2") size cable

RF Output #2: FSB-1 (Big Clamp on) – 3 turns of RG-8 (1/2") size cable

RF Output #3: FSB-1 (Big Clamp on) – 3 turns of RG-8 (1/2") size cable

ALC/Relay Cable: FSB-1/2 – multiple turns through choke – ½” diameter hole - Both ALC and Relay together thru same ferrite

AC Power Line: FSB-1 (Big Clamp On) – 3-6 turns through center


Mercury LUX - 8 Ferrite Filters

RF Input: F240 Ring – 5-9 turns of RG-8X (1/4") size through center

Data: FSB-1/2 – multiple turns through choke – ½” diameter hole

AC Power Line: FSB-1 (Big Clamp On) – 3-6 turns through center


 

Also make sure you connect a good RF ground to the transceiver ground post.

Note to Flex Radio users:  Use snap on ferrites for firewire cable, speaker cable and mic cable,  Ring ferrites for Antenna output and DC power.

For additional RFI suppression, use a feed line choke at the antenna to suppress common current on the coax feed line – see our store for feed line choke alternatives for use at the antenna.

 

If you use a linear amplifier we have RFI kits for linear amplifiers that help suppress RFI in your shack or in your neighbor’s house.
