WA6YBD's DYI e-Load (300W Test Load)

Bill Melody (WA6YBD) When I first started thinking about building this thing I ran across a kit available from China on eBay for $10. It comes with

all the parts and a PC board. I couldn't even buy the power FET's for $10 let alone all the other parts so I bought the kit. I had a chassis box, heatsink and ammeter left over from another project and was able to put them to good use. 

My DIY load should handle 300 watts (or so they say) but even at 100 watts it heats up quickly. I have not yet put a fan on the heatsink yet but I will.  I did blow some air on it and it really helps. Photo1 - Photo2

KR7KP's & K7KF's Loop Entrance Dual Coil Static Grounding

Kerry (KR7KP) and John (K7KF) among others use this configuration to "bleed" off static voltage from wire antennas.  This may reduce noise and unwanted voltages from reaching the receiver.  KR7KP

Icom IC-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 below.  Much thanks to Kerry (KR7KP) for use of his shop, parts and "modeling" expertise.  And, the chips and salsa were great too!

Streaming Audio - No longer available (More to come)

(Currently Out of Service) 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 3.737/3.742 megacycles each morning at 0500 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.
