Woody, I had looked at the K4DPK PEP adapter, but oped for something I thought was more fun. On my W4, I use the the circuit from the article by John Fielden GW4NAH, pg 17 of Sept 1989 HR magazine. Great weekend project and works FB. No "extra" test equipment needed. I power it via the 12 volt aux port of the PS7. I thought John's idea of a 2.7K resistor at the power source was a great safety feature. I use RG-174 cable to carry the power. Mounted the perf board and PEP/average switch on a little home made aluminum bracket. Fully reversible with no holes, etc.
For those not aware, you can get HR mag on CDs from ARRL and other sources. IMO, it is a super resource for learning a great deal about Ham Radio specific electronics and theory. 73, Ron WD8SBB --- On Sat, 11/26/11, Woody <ko4...@gmail.com> wrote: From: Woody <ko4...@gmail.com> Subject: [Drakelist] WH7 PEP mod To: "Drake List" <drakelist@zerobeat.net> Date: Saturday, November 26, 2011, 11:17 PM Hello, I hope everyone had a Great Thanksgiving and ate tooooo much!!!I purchased the PEP kit from Phil (K4DPK) who advertise's on QTH and installed it in about 5 min. so you know it was an easy install. And it works Great. Phil is a Stand up kind of Guy, he's a Great person and great to do business with and his products WORK and are ready to go when you get them. He is a friend of mine but that has no bearing on my posting this, his PEP kits work!!!! While I was in the WH7 I decided to add a little light to the meter, since you need power to operate the PEP meter I thought I'd add a blue LED above the meter, I had some laying around and within a couple more min. I had a pretty Blue light shinning on the meter of my WH7, it looks good and you don't have to mod. anything.
