DuWayne's Place: 8307 power meter repackage
http://kv4qb.blogspot.com/2016/10/8307-power-meter-repackage.html
A place for me to share information about my latest Ham Radio and electronics projects. Thursday, October 6, 2016. 8307 power meter repackage. I have been playing with the CAD software I use with the 3D printer. I tried several ways to make a housing with a top and bottom piece, but couldn't get one to print that held together tightly. I kept the SMA connector for the input to the meter. That allows me to use a cable to check output levels of modules with connectors,. Subscribe to: Post Comments (Atom).

I quit playing with the new toy (3D Printer) long enough to populate and test the AF amplifier section of the SMD BITX. With everything connected but the signal generator turned off and the Volume pot all the way up I had a fairly flat baseline out to over 16Khz. that had a value of about -115 dB at around 1500 Hz. Not sure where the 1 Khz. spikes are comi...Next to b...

The North Georgia QRP Club has been selling several small kits for the last few years. One of them is a simple QRP SWR meter, but the small meters that were originally used are becoming hard to get and much more expensive then when the kit was first offered. Several members of the group spoke to me about coming up with an updated replacement. I decided that I woul...

A place for me to share information about my latest Ham Radio and electronics projects. Tuesday, March 15, 2016. Sweeperino Jr. Part 1. Now that I have the SWR meter nearly finished, I want to get back to working on the spectrum analyzer. I will need to build and align several filters that are higher in frequency than either the SNAJr. or the Chinese SNA cover. Lookng at some posts by Asher Farhan on his blog, he has a simple SNA that he called the Sweeperino. When I built the power meter I found it was ...

A place for me to share information about my latest Ham Radio and electronics projects. Thursday, May 26, 2016. Four Days in May 2016. Well because of my schedule it was only Two Days in May, but it was still fun. I really enjoyed the seminars on Thursday, and was pleased to hear Paul M0XPD mention the SNA Jr. during his presentation. The WBB was great! I spent a lot of time talking about and demoing the SNA Jr. After suggestions from several people, I am in the process of writing an article on it for QR...

The narrow filter about 1Khz uses 9 crystals and has two in line amplifiers between each set of 3. The wide filter should have about a 400Khz bandwidth and is comprised of 5 LC networks. I wound some toroids and tried to...

http://kv4qb.blogspot.com/2016/10/bitx-40-p.html
A place for me to share information about my latest Ham Radio and electronics projects. Monday, October 31, 2016. BITX 40 v 3. I want to make a few minor changes to the kit, first I wanted to use a 10 turn pot instead of the one included in the kit. Along with that I will add one of the re-packaged DL4YHF counters I designed a couple years ago. I also will use an external hand microphone with PTT instead of the electroet mic. that came with the kit. November 1, 2016 at 7:15 AM. What would you charge?
