G3ZPR erecting a Comet hf vertical antenna

Thanks Dave & Viv for your kind help in supplying and putting up this aerial for me!

First off I’m sorry for the poor quality. It will get better very soon. Showing a very portable end fed dipole HF antenna setup with a 20 gauge trifilar wound 9:1 unun transformer I made and currently sell on eBay. My username is “nelson_antennas”.This antenna matchbox will work 160-m trough 6m with a single wire antenna. 160 and 6 meter will depend on your tuners capabilities but tunes up and works well with my LDG-YT 100 and 897D . Antenna can be ran as a sloper/vertical or inverted L. Counterpoise wires are not necessary but can help on some bands but that’s the fun part of HAM radio….Experimenting! Enjoy

Martin O’Shield – Software Defined Radio Demonstration

Software-defined radio (SDR) is a radio communication system where components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system. While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which used to be only theoretically possible.
A basic SDR system may consist of a personal computer equipped with a sound card, or other analog-to-digital converter, preceded by some form of RF front end. Significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware. Such a design produces a radio which can receive and transmit widely different radio protocols (sometimes referred to as waveforms) based solely on the software used.
Software radios have significant utility for the military and cell phone services, both of which must serve a wide variety of changing radio protocols in real time.

Field Day C A R L 2013

A lot of youg people won rubber ducks for performing a Morse Code test at the Arizona Science Center C.A.R.L. Amateur Radio Station during the International Amatuer Radio Field Day on 22 June 2013. Some NEW HAM Volunteers were inducted also. That’s always good news.

Baofeng UV-5RA Handheld Ham Radio with FM Transceiver

This is a review/description of the Baofeng UV-5RA Ham Radio. I got this off Amazon for including the Nagoya NA-771 antenna. If you want to start getting into the hobby of Ham’s and want to use a simple handheld, this is the one for you. Although the instruction manual doesn’t tell you how to program in the repeaters you can easily find videos on YouTube.

RTL-SDR HF SDR# SDRSharp Airplane Tracking HFDL w/MultiPSK & HFDisplay

HF Airplane Tracking HFDL with MultiPSK & HFDisplay

Using SDR# with the RTL-SDR, but the MultiPSK RTLSDR Key setting will allow you to connect directly. I haven’t found yet how to set the Ham-It-Up converter offset in MultiPSK RTLSDR config, but the results should be similar.

Receiving Spanish DRM (Digital Radio Mondiale) radio, transmitted from Noblejas, Spain. DRM is digital shortwave radio.

Received from Auckland, New Zealand. Using the nooelec “Ham It Up v1.0” upconverter circuit, an R820T RTL2832 RTL SDR tv dongle with a random wire antenna about 15m long.

Used SDR Sharp as the software radio and DREAM as the DRM decoder.

RTL SDR is a low cost software defined radio. The RTL SDR dongle can be purchased from http://www.amazon.com/gp/product/B009U7WZCA/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B009U7WZCA&linkCode=as2&tag=youtube0ae9-20&linkId=RR5VUVIXLMIB43M

Are We Living In A Multiverse?

Catalyst: Custom Universe – Consider one of the most perplexing problems of modern physics and philosophy: is the universe fine-tuned for us?

Einstein predicted them and finally a telescope may have found evidence they exist – gravity waves. And, excitingly, the discovery supports the idea that there may be many universes out there, of which ours is just one. Custom Universe explores the idea that we could be living in a multiverse.
