This is a troubleshooting video, I have an FT-450AT displaying a really strange issue. If you know what’s causing it, leave a message in the comments! Thanks!
I start this series by introducing some basics about antennas, antenna tuners, antenna analyzers and noise / interference / QRM / QRN. In this video: I show the setup I’ll be using when I test the reception of the K-PO WR2100. I introduce the Tecsun (Kaito) PL-389MP Short Wave radio and use it to track down the source of my radio interference / noise / QRM. I’ll also chat about radio wave propagation in the next video. Equipment used / mentioned in this video series: * K-Po WR2100 PLL Synthesized World Band Receiver. * Yaesu FT-897 HF/VHF All Mode Transceiver * Yaesu FT-950 HF / 50MHz band All Mode Transceiver * Yaesu VX-6 Submersible Dual-Band FM Transceiver * Yaesu FT-817ND solar powered portable go-pack * Yaesu FRG-7000 Receiver * RigExpert AA-200 Antenna analyzer * Simple wire antenna * Par electronics Par End-Fedz EF-10-20-40 full length half wave dipole * Buddipole™- hf/vhf portable dipole antenna system * MFJ Deluxe Travel Antenna Tuner – MFJ-904H * Amateur Extra HAM radio license – KD8LON

Ham Radio Deluxe v5.1 Release Announcement
HRD Software, LLC Tampa FL, St. Paul MN, Pittsburgh PA – February 8, 2012 HRD Software, LLC announces the release of Ham Radio Deluxe 5.1. This version incorporates fixes and some new features for DXers.
“This is our first release since obtaining the source code about 90 days ago,” said Mike Carper, WA9PIE. “My partner, Rick, W4PC has done an outstanding job at becoming familiar with the code and developing the applications. We were fortunate to have a few key resources like Chuck, K7PT and Terry, G4POP to help us QA the builds as they’re developed.”
The 5.1 release is being made available at no charge to users registered on the HRD website. The focus for this release was a few items from the ToDo list – bug fixes, added rig support, and a few enhancements.
Mike said, “I think we’ve taken a balanced approach to getting something out quickly that satisfies a broad range of needs. I hope hams will enjoy the improvements. Obviously, this is only the beginning. We’ve got big plans and high-expectations for HRD in the future.”
Following the 5.1 release, HRD Software intends to focus on more fixes and significant feature enhancements for v6.x with a target release at the Dayton Hamvention 2012.

Note from K3RRR: HRD is a fantastic piece of software that I have used for years. If you don’t already have it, download this new version. It may be the last version that is free. For those of you who don’t know, Simon sold the software to HRD Software, LLC of Tampa, Florida who intend to continue its development as a commercial (ie, not free) product. For me, HDR was never free – I contributed via the Donate Button to Simon. So, if the new company provides worthwhile enhancements for a fair price, I may be motivated to purchase the next versions!
HF Digital Voice has been around a while, but it hasn’t really caught on the way D-STAR has on VHF/UHF. That could change with a good, open-source codec – CODEC2 – that’s on its way. In this forum, Mel Whitten K0PFX reviews the various options for HF Digital Voice, from AOR’s hardware modems to the sound-card modes. In our Poster Frame, Mel is joined by CODEC2’s author David Rowe VK5DGR. David had his own talk on CODEC2 at the 2011 DCC (available at www.ARVN.TV), and he also made the keynote talk at the Saturday night banquet, where he spoke about a service project he’s involved in called The Village Telco (and yes, it’s at www.ARVN.TV as well).

It has a nice online program which tests your download and upload speeds. If your computer is connected to a Router or Switch you can log into your router or switch and view its traffic log to see how many Bytes per second your Network, Wireless Network, and Internet (WAN) is sending and receiving. You need to read your manual to learn how to log in to your router or switch. Resource Monitor, Networking tab in Task Monitor, and Performance Monitor can all be used to measure your Network Performance in Windows 7 and below. They are preinstalled with Windows when you installed Windows on your PC. Resource monitor can also stop process. Networking tab in task monitor just shows you a line graph of the current network activity. Performance monitor can be set up to add a Network Counter which can be displayed as a bar graph, line graph, or Real-time report. If you notice your network is always busy, it may mean you have spyware on your computer which is sending your internet and computer habits to a remote computer. It can also mean someone has been stealing your network connection to do something like sharing files on Bittorrent, p2p file sharing programs, or they are copying your knowledge without your knowledge if your router bytes sent and receive speeds are unusually high when you are doing …

The Model MR330 series fiber optic position sensor system is my latest innovation.It is an all-optical design immune to any electro-magnetic interference such as lightening, radiation, magnetic fields and other harsh environmental conditions. The fiber optic aspect of the sensor also makes it perfectly suited for long distance position sensing over hundreds of meters without being affected by ground loop problems. This innovative product measures absolute angular position from 0° to 360° with 13-bit (8192 count) resolution at speeds exceeding 2500 rpm and distances up to 300 meters. The sensor modulates the optical signal based on the exact position of the sensor disk. This modulated optical signal is analyzed within the controller and translated into the position signal. Because the sensor is electrically passive it can be deployed in EMI/RFI intense environment without being disturbed by such interference.

#107- Sensors Locate Radio Interference (w)1
Heed Audio from Hungary makes some great pieces of audio gear. The small great looking black boxes are engineering masterpieces that sound full bodied and alive. The Questar MM uses the exact same MM circuitry from its Quasar big brother (quite more expensive top of the range MM/MC stage), with balanced design and quality components. The internal construction of the QUESTAR meets the most critical high-end standards in every respect. The amplifier employs an entirely dual-mono configuration and uses a two-stage – passive/active – RIAA equalisation. Gain adjustment has been optimised for maximum headroom and highest signal-to-noise ratio. Component parts are selected to exacting tolerances matching those of our flagship Quasar. The QUESTAR are suitable for any line-level amplifier input, and can easily drive virtually any length of interconnect. There is no internal wiring or binding, and all high-current parts of the circuit are shielded. Both models feature gold-plated RCA terminals soldered directly onto the PCB, limiting all signal paths to a bare minimum. The QUESTAR utilise an external wall-wart power supply to avoid undesirable electro-magnetic interference within the chassis. Technical specifications Input: 3 mV/47 kOhm (Questar MM) Frequency range: 20 Hz – 20 kHz/± 0,3 dB Gain: 42 dB (Questar MM) Signal/noise ratio: 82 dB (Questar MM) Headroom: 20 dB (Questar MM) Channel separation: 50 dB (1 kHz) If you’re thinking about getting a Cambridge Audio 640P Stage …

An attempt at using microcontrollers for amateur radio applications. The Freetronics KitTen kit I built came from their stall at the 2012 Melbourne Mini Maker Faire. Microcontroller projects involve software, hardware and the minor miracles that must happen before computers will talk to one another. Hence they have traditionally been for advanced electronic hobbyists and professionals only, because of the many things that can go wrong. Arduino promises to make microcontrollers simple, cheap and accessible. Has it succeeded? Watch this video as I, who has a record of nothing but failure in these things, attempts to get a project going, and then design some of his own. At one point the quest almost got derailed. An account of similar symptoms and the builder giving up was read. However a solution was found and the development could continue. Radio projects featured include a beacon, an automatic CQ caller (configured as a QRPp transmitter) and a foxhunt transmitter, all with their own customised code. I recommend the kit featured ( www.freetronics.com ). It came direct from Freetronics though Jaycar also stock a good range. The January 2012 issue of Silicon Chip magazine has a good beginners’ introduction to Arduino and I suggest also getting this. NOTE: A question that those used to building from scratch will ask is whether you can buy the chip used ( Atmel ATmega328P 28 pin ) seperately, program in this unit and then insert into your own circuit board. You can, but need a …
