QRP HomeBuilder - QRPHB -: Onto Jupiter
http://qrp-popcorn.blogspot.com/2015/04/onto-jupiter.html
QRP HomeBuilder - QRPHB -. Popcorn Radio Electronics and Radio Astronomy. Tuesday, 14 April 2015. I spent some grand time on the bench this Fall and Winter. On May 3, I'll cease bench experiments blog posting and go outside in our garden. To keep in touch with other radio and QRP work bench enthusiasts over the spring summer, I'll employ Twitter. Here's a quick glimpse at the front end filter — amplifier in test mode. I swept for S21 and performed DC measures last weekend. Above —1 of my first rege...

Radio blog. and other stuff too. Applying for a Florida Amateur Radio license plate. After about 45 minutes of hunting for the code, they finally found it – “. 8221; I am apparently not the only one who has had this problem in the state of Florida, John KU8Q has written a helpful article explaining the exact process he went through (very similar to my experience). It’s here, on the LWRA website https:/ lwra.us/wp-content/uploads/2010/07/Call-sign-license-plate.pdf. January 7, 2017. February 22, 2017.

Radio blog. and other stuff too. Radio astronomy with RTL-SDR and RasbPi. Https:/ www.hackster.io/mariocannistra/radio-astronomy-with-rtl-sdr-raspberrypi-and-amazon-aws-iot-45b617. This looks like an interesting project. Might have to experiment with this a little. I’ve been kicking around some ideas about a homebrew radio telescope – basically a 1400MHz 15-20 element yagi, fed into an SDR dongle through a couple of LNA’s and a bandpass filter. Also good info from the British Astronomical Association.

kd0ar's Ham Blog: 2304 Yagi
http://kd0ar.blogspot.com/2010/11/2304-yagi.html
Saturday, November 13, 2010. Being I got some power out of the transmitter, I had an idea a couple of days ago, and thought about building a yagi antenna for 2304. I went with the DL6WU design, but with a twist. Instead of doing the folded dipole and balun, I went instead with the WA5VJB unbalanced half - folded driven element. Everything else about the yagi is in accordance to DL6WU's calculations. I used the VK5DJ Yagi Calculator program to design this antenna. The driven element was designed by me...

Saturday, February 13, 2010. Softrock and the Digital Modes. There are 2 programs you will need in order to make everything play nice. First is "Virtual Audio Cable". it can be downloaded from here:. Http:/ software.muzychenko.net/eng/vac.html. When you get it, you will need to create 2 virtual sound devices. There are good instructions at the above website on doing this. One will be needed for receive, the other for transmit. Http:/ com0com.sourceforge.net/. Ham Radio Deluxe sets up in a similar fashion.

Wednesday, September 14, 2011. Useful Microwave Test Gear. I bought it so that I can use it as a reference oscillator for various brick oscillators. I have 2 bricks in my possession, one on L band, the other on 6200 or so MHz. Here is a test setup showing the unit in operation, referencing my L band brick:. Mike H - KD0AR.
