Icom 2KL Power Supply Modification

The power supply for the IC-2KL uses two, close to obsolete, power transistors (2SD797) in parallel for the 40VDC to the IC-2KL solid state amplifier.  I was able to obtain 4 of these "original" Toshiba manufactured NPN devices and decided to take KR7KP's advise on modifying the power supply so that all 4 could be used in parallel.  The thought here was to split the load on these devices so they might last literally "forever".  Photos of the modification are available at SmugMug.  Much thanks to Kerry (KR7KP) for use of his shop, parts and "modeling" expertise.  And, the chips and salsa were great too!

Streaming Audio

Click here for audio from an ICOM IC-756.  Listen to others, then transmit and listen to your station for comparisons.  Enjoy and have fun playing with settings and different microphones, etc.

The radio is generally tuned to 3.737 megacycles each morning at 0600 Pacific Time.  If the radio is not tuned to that frequency, please send an email to w9pci@w9pci.com.  There is a significant (about 10 to 15 second) delay so you may transmit and listen to your own audio for testing, (be sure your operating license permits your to transmit on the selected frequency).

Audio Streamed by the BroadWave Streaming Audio Server by NCH Swift Sound Software.  The BroadWave Streaming Audio Server software is running on an old Compaq Presario 1200 laptop.  This laptop also runs Echolink, Ambient VWS weather station software and digital packet programs.

The OS is XP Pro Sp3 on a Celeron 597Mhz CPU with 312Mb of RAM - amazing!
