HRWB 253 - QRP Labs

In this episode we meet Hans Summers, founder of QRP Labs, the makers of the wildly popular QCX, QDX and other great portable HF QRP radios.  Hans tells about his journey through the design process and all details on his latest creation the QMX multi-band transceiver.

In this episode we meet David Gleason, NR9V, who makes radio interface devices to connect to AllStar and other Radio Over IP applications.  We introduce you to AllStar, talk about some of the technical details of the system, and explore the pros and cons of digital voice CODECs.  David's company AllScan offers a veriety of radio interfaces, computers and accessories.

In this episode we talk about our workbench projects AND take a deep dive into gift recommendations for your favorite ham.  Topics include gifts for the workbench, the shack, portable operations and stocking stuffers. Warm up your wallet !  

In this episode we meet Paul, KI7ADC, and Raoul, W7RPS, both avid users of the Icom IC-905 VHF/UHF/SHF radio.  We talk about what attracted them to operate on the microwave bands and what it took to get their portable stations all set up.  Paul and Raoul live in the Portland metro area and have had experience on the ground and mountain topping with the IC-905.  They have explored using SSB, FM, D-STAR and ATV modes on 1.2 GHz, 2.4 and 5.6 GHz. If you have ever been interested in moving up the frequency spectrum to the microwave bands, the IC-905 is a very easy way to get up and on the air.

In this episode we meet Richard Dillman, W6AWO, one of the key people responsible for putting historical shore station KPH back on the air.  In this fascinating interview, Richard tells us about the history of KPH, when it was decomissioned and his efforts to put the station back on the air.  This project is managed by the Maritime Radio Historical Society.  Today KPH is on the air using commercial HF marine frequencies and on the ham bands as K6KPH. Many thanks to our good friend Kevin Mattison, KM6WUM, for pulling this show together.  You can hear more about Kevin and his portable satellite tracker project in HRWB episode 120.

In this episode we meet Tony, K1KP, the developer of polar modulation that is being used in the new Flex Radio Aurora radio.  Polar modulation is a technology breakthrough that allows Flex Radio to make an integrated 500 watt HF/6m transciever, power supply and antenna tuner in a small light weight package.  With better than 80% efficiency, the Aurora produces less heat, consumes less power and is smaller than conventional radios.  Tony, K1KP, has been developing this technology for over 10 years.  In this episode we will hear about Tony's journey as he pioneered polar modulation in amateur radio.

In this episode we meet Keith Elliott, W6KME, from the Conejo Valley Amateur Radio Club.  Keith has been ordanizing the club's Field Day event for the past 5 years and has learned a lot about how to set up a very large, multi-transmitter station.  Keith shares both the technical tips and tricks as well as management ideas to make everything run smoothly.  Running a class 24A station, the Conejo Valley ARC has one of the largest Field Day stations on the air. Keith is very active with Ventura County's ARES and ACS (Auxilliary Communication Service), as an Assistant Emergency Coordinator and frequent participant in public events.  He has been recently elected as the new Section Manager of the ARRL's Santa Barbara section, including Ventura, Santa Barbara aand San Luis Obispo Counties.

In this episode, we meet Simon Wilton, G7HCD / VA3SII, a prolific designer, tinkerer and ham radio operator.  Simon describes some of his projects including 3D brackets for radio control heads and his design tools of choice.  Simon is also the originator of the phrase "Good after-evening-noon" often heard on our show.

In this episode our good friend Pat Hensley, W5WTH, joins us to talk about his latest super creative electronics projects and his design process.  Pat comes up with some of the coolest ham radio projects as he explores the world of electronics and microcontrollers.   From his software that makes a modern Flex Radio sound like an old unstable tube radio from the 50's to his beer can CW key, Pat comes up with projects that are really fun.  He publishes all of his projects as open source on his blog web site whiskeytangohotel.com

In this episode we talk with Eric Guth, 4Z1UG, the host of the popular QSO Today Podcast.  Eric has produced over 500 interviews with interesting and influential amateur radio operators creating an amazing repository of ham radio history.  Eric's body of work informs, entertains and inspires us while we all create our own ham radio journey.  Eric's work is a valuable gift to the amateur radio community. Eric shares his own personal ham radio journey and plans for the future.  We were all very happy to hang out with Eric and talk radio.
