Title: Ranger II parasitic suppressor Post by: N4RMT on July 20, 2016, 11:27:27 AM Good day gents.
Could someone tell me what the value is of the plate parasitic choke resistor on the Ranger II? This one's burnt to a crisp, and the schematic and parts list just list the whole assy. as "L9". Thanks Title: Re: Ranger II parasitic suppressor Post by: KA2DZT on July 20, 2016, 10:40:05 PM Those resistors are usually in the range of 50 ohms. Someone should know exactly the value used in the Ranger.

According to Carl, 33 ohms. He also gives the values of other editors to check. --Shane KD6VXI Title: Re: Ranger II parasitic suppressor Post by: N4RMT on July 21, 2016, 03:03:03 AM http://amfone.net/Amforum/index.php?action=printpage;topic=34063.0 According to Carl, 33 ohms.
