In this episode we bring back our good friend Dan Quigley, N7HQ, to talk about restoring older radio equipment.  Should you return an old radio to it's original state or repurpose the chassis for a more modern project with the look and feel of a classic radio of the past?  We explore various approaches to restoring radio equipment including tools, test equipment and process.

Dan is the director of strategic programs at Flex Radio and brings decades of professional engineering and ham radio experience to the discussion.

Mike and Smitty join George and Jeremy to take a DEEP dive on the fundamentals of designing a mixer for all of your audio sources in the shack.  This is a continuation of the station controller design series.

Gaston - https://www.youtube.com/watch?v=uUoEuaQ_l2Q

• Location: Tonto National Forest - evening/overnight operation
• X-factor: heat
• Man portable: 58.5 lb pack including 8L of water (17.5 lbs)
• Conditions: 101- 85 degrees (F)
• Did not participate in FD activities
• Gear: 
• • PackTenna Linked Dipole: 20m/40m (80m not used)
  • PackTenna TrekMount with Comet BNC-24 antennas for 2m SSB
  • FT-818 with ARMOLOQ TPA pack frame, 4.5Ah LiFePO4, 20 watt Powerfilm solar panels, Buddipole PowerMini
• EmComm Tools testing successful: APRS text msg (SMSGTE), 40m Winlink status email, call lookup

Mark

• N6EOF 2A Santa Barbara. 631 QSOs: 351 SSB, 94 Digital (FT4 and FT8), 186 CW. 100W so 2x multiplier.  1822 Total QSO points, 350 Bonus points. Final score: 2172 points! (but it’s totally not a contest.)
• Had a great turn out! About 12 people total, 7 active hams who played with the radios at least a bit.
• Ran entirely on solar power, only spun up the generator for a couple minutes to make sure it worked, and show another person how (it’s mod’d for Propane.)  2 stations, 100W both, using nothing but solar. I’m really proud of that.
• SSB station: FT-920, on an EFHW, cut for 40m (so resonates on 40/20/15/10m), but added a loading coil and stub to add 80m. It worked really well, but required more tuning at the radio than I anticipated.
• • The loading coil was 13 turns of antenna wire around an FT140-43 (which should have been about 110uH, except that it totally isn’t, it’s 150uH, I should have done 11 turns… Oops…)  All the designs I’ve seen show a linear coil of antenna wire around a form, not a toroid. I’m wondering if the capacitive coupling of the toroid was different enough from the linear coil to affect tuning on 40m and above.  (The wrong inductance should have only negatively affected 80m, which definitely was tuned too low.)
  • Used the feedline as a counterpoise, put a current choke 1:1 balun about 12 feet from the feedpoint: 13 turns of RG-8X around an FT240-43. You think wrapping magnet wire around toroids is a pain?
• CW/Digital station: Club member brought his Packtenna clipped dipole. Used it with his Flex6600 and Maestro. Worked a charm.
• 20m SSB was CHEEK BY JOWEL...

Rod VA3ON 

• Teamed up with my friend (and Elmer) Peter West VE3HG to create a small scale field day for us and our two Padawans, Iuliya VE3UHA  and Dante VA3DNF. (4 total)
• Both teenagers licenced as Basic with Honours during the pandemic shutdown, but had yet to operate HF. Used the Oakville club call VE3HB. At the scenic “West Estate” we got a few antennas up (Dipoles, horizontal Endfed and verticals)
• 5 Watts on two Elecraft KX2 Stations (Commonality of rigs, preserved learning):
• • Station A: CW 
  • Station B: Phone and FT8 on the other
• New HRWB Logger appliance (with N1MM) - Avita Magus II [WT9M10C44] 10 Inches Intel Celeron 4GB RAM 64GB Storage Touch 2-in-1 Windows 10 Tablet PC Black     - rocked
• Conditions
• • Phone was horrific on Saturday
  • FT- not much better - could hear lots but nothing worked well
  • CW great (as usual)
• To make CW workable we used a CW reader and keyer with preloaded exchanges and a keyboard. An approach I’ve not used before with rookies to shortened the learning curve. Emphasis on learning and getting the tempo.
• We may be seeing a lot more of these two as CW contesters - they were aggressive!

Segment 3 - EmComm Software Project by Gaston KT1RUN

• What is the purpose?
• • API and web app for field expedient digital communications platform that runs on RPi
  • Offgid, mobile-first and 1-click digital operations
  • Headless: eliminate need for VNC and/or external display/keyboard/mouse
  • Lightweight: small footprint memory, CPU and disk => conserve power
• What does it do?
• • Allows headless operation of various ham radio tools (Pat, YAAC,direwolf, etc.) on a RPi (everything runs on the Pi; the web browser is the interface)

NOTES

Reminder to Jeremy, post notes for HRWB132 onto web

In this episode we interview Derek, KD9MEQ, president of the Purdue University Amateur Radio Club.  Derek and his fellow club members have created a very successful amateur radio club that has grown significantly in the last few years.  The combination of welcoming leadership and a LOT of hands-on projects have made this an outstanding college radio club.  The club has built antennas, radio, rotors and many other projects.  Join us in this episode as we explore what makes for a successful club, how to attrack young people to our great hobby and we learn about a lot of cool projects along the way.

Live from the QSO Today Virtual Ham Expo, we chat with our special guests Thomas K4SWL, Kirk NT0Z, John W7DBO and Troy K4JDA.  We talk about our workbench projects, take listener questions and talk a lot about antennas.

In this episode we meet Daniel Winn, WV1T, a very active portable ham radio opertor.  Daniel was searching for a way to filter out strong local signals when operating in the field and he started building stub tuned filters with coaxial cable.  This simple and cost effective approach is a great way to build notch filters that can significantly reduce unwanted interference from transmitters operating at the same location but in other HF bands.  This is a great technique for Field Day and similar activities.  Daniel holds an extra class amateur radio license and is a professional electrician.

In this episode we talk with Carlos Felix, KD9OLN, an avid skydiver and ham radio operator that blends his two hobbies into one !  Carlos works stations on HF and VHF while skydiving from 14,000 feet.  We talk with Carlos about his journey to skydiving and ham radio, the gear he uses and how it works. 

In this episode we have our good friend, Dr. Doug Millar, K6JEY, join us to talk about multi meters, what they do and buying recommendations.  Every ham radio operator or DIY electronics fan needs a good multi meter.  But should you spend $20 or $200 on a meter and what's the difference?  Doug explains it all.

In this episode we meet Hamilton Carter, KD0FNR and his daughter, Hamie Carter, KO6BTY.  This amazing father / daughter team have build and deployed multiple creative radio projects.  One in particular, Project TouCans, puts a QRP transciever right at the dipole antenna feed point eliminating coax cables and communicates with the operator's station over Bluetooth.

Follow along on thier radio adventures on their blog page at https://copaseticflow.blogspot.com

Brittany KE8LCA is back to continue our “Tech in Technician Discussion where we explain concepts from the Amateur Radio Technician Exam in practical terms.  We also talk about our ham radio goals for 2019 and answer listener questions about Ham Radio topics. Finally, we discuss the processes and equipment used by us to produce the Ham Radio Workbench podcast.

In this episode we talk with Rex, KE6MT, the SOTA (Summits On The Air) program manager for California.  Rex gives us an update on the SOTA program and why you should be interested in this great aspect of ham radio.  In the last segment we talk about the Wilderness Protocol and how, while it's a good start, its just not very practical.  We define a new proposal called the Adventure Radio Protocol which uses CTCSS tones to signal various type of activity on the air on a common frequency of 146.580 MHz.  Of course, as a HRWB episode, we also turn this into a hardware project that is a PCB that can handle the tone decoding and alerting.  The Adventure Radio board can be used at a base station, remote receiver or on a repeater system to alert listeners for traffic or emergencies.

Check out adventureradio.info for more details.

Kenneth Finnegan W6KWF talks to us about building internets (separate ot “The Internet”) to support communication in Ham Radio Activities such as Emergencies and Field Day, without radios.

In this episode, "special guest" George, KJ6VU, talks all about how to build a repeater system.  We explain about the radios, antennas, feedline, duplexers, controllers and more.

In this episode we talk with Kyle, AA0Z, who has extensive experience building and operating remote stations.  Kyle tells us about his latest project to remotely automate a big contest station.  We talk about using Node Red for station control programming and ask Kyle how he approached remote monitoring and control of the station.  We also do a quick design review of George, KJ6VU's, new station controller design and see how close it comes to meeting Kyle's remote station control requirements. 

Eric Swartz WA6HHQ, co-founder of Elecraft, joins us to guide our understanding of RF receiver performance specifications.  Eric introduces us to common receiver specs such as Sensitivity, Noise Floor, Dynamic Range, Intermod Dynamic Range, Phase Noise, and RMDR.  He tells us what they mean in real-world receiver performance terms, how they are tested, and whether it’s better to have a higher or lower number in each one.  It’s also the final episode before the 2018 Hamvention and George and Jeremy share our plans for our Booth, special offers, and exclusives for show listeners who stop by booth 3104 in Xenia.

RF Receiver Specifications Guide from Eric Swartz WA6HHQ

Elecraft Mailing List - http://www.elecraft.com/elist.html

Sensitivity - How well can the receiver hear weak signals?

• Minimum Discernible Signals - noise is generated inside the radio from the amplifier stages and how much amplification is available in the receive chain to bring a signal above the radio’s internal noise floor
• As sensitivity increases, you can degrade dynamic range
• To measure, start by injecting weak signals until you observe the signal level out of the speaker roughly double in amplitude (3dB)
• Lower values are better (bigger negative number), allowing you to detect weaker signals
• Most HF radios are between -125 to -130 with -135 to -138 being on the higher side of performance

Noise Floor

• The internal noise figure generated by the radio with the antenna removed

Dynamic Range

• Strong Signal Handling - how does the radio perform when there are strong signals adjacent to where you are tuned?
• IMDR3 - Intermodulation Dynamic Range
• When multiple strong received signals overload the first receiving amplifier in your radio, the signals get clipped
• When the radio has a broad banded receiver, this clipping begins to act as a mixer and creates intermodulation showing up at different frequencies
• Additional unwanted signals are created in the receiver when multiple strong signals are present
• To measure, begin with two signals apart - the difference between the MDS/sensitivity and the level required to set the signal generator to to cover up the weak signal
• Higher values are better - 90dB range above noise floor is average, mid 90’s to 100 dB is on the higher side of performance

Blocking Dynamic Range

• A strong signal overloading your receiver thereby reducing the gain of the receiver.
• Receivers can have challenges when a strong signal is physically near the radio
• To measure, inject a signal until it causes receiver overall gain to drop one DB
• Higher values are better - typical better than 130dB of BDR, mid 130s to 140s is on the higher side of performance

Phase Noise

• An indication of the quality and “cleanliness” of local oscilator (VFO, or Crystal Master Oscillator)
• Denotes whether they introduce jitter or noise to the received signal
• Lower is better

Reciprocal Mixing Dynamic Range (RMDR)

• RMDR is tied to phase noise
• Impacted by how clean your oscillator is
• To measure, listen in 500hz bandwidth and measure how strong an injected signal has to be to raise the noise floor on the freq you are tuned to (1-3dB noise floor increase)
• This ratio is the RMDR
• Higher values are better - 110-115 dB
• As multiple signals get closer, the RMDR drops

Kirk is the author of Stealth Amateur Radio - Operate From Anywhere and he is a monthly columnist for the Spectrum Monitor magazine.

In this episode we interview Andreas about he ham radio journey and how he has become a big YouTube celeb.  With over 300,000 subscribers and 400 videos, Andreas has become one of the most influential mentors in for hands on hardware and software experimentation.  Andreas has a remarkable talent for explaining complex technical subjects including radio propagation, software defined radio, microcontroller selection, and more. 

In this episode we meet Morten LB0FI, Kjetil LB4FH, Tobias DL3MHT, and Bård (Bob) LB5JJ from the European Ham Radio Show on YouTube.  Walt, K4OGO, was not able to make the show this time.

The European Ham Radio show is hosted by Morten and the team talks about many aspects of ham radio on their weekly YouTube show.  Topics include radios, antennas, homebrew and a big dose of portable operating.  We were invited to join them on their show a few months ago and had such a great time, we wanted to introduce them to our HRWB audience. 

We hope you enjoy the discussion of ham radio from a European perspective.

George, Brittany, and Jeremy just returned from Hamvention 2019 in Xenia, OH.  We had a record year this year - there was no shortage of folks who stopped by to say hello and to pick up our build projects!  In fact, we were so busy that we didn’t get our usual level of coverage this year. A big THANK YOU to everyone who stopped by to say hello and support us.  A special big thanks to the guy who bought my go box!

We interview Eric from Elecraft on the new K4 Direct Sampling SDR HF Transceiver, Mike from Flex Radio on the new multiFlex feature, and Kaitlyn from Digilent on the new Analog Discovery Studio.  We also include Hans Summer’s presentation from FDIM.

This week we are joined by Rob KA2PBT and Evan KD2IZW to talk about building creative solutions to post emergency or disaster communications problems. Rob is engaged with his local high-school and has been working with youth to engage them in hands-on engineering and problem-solving using amateur radio. Evan is a former student who lead a team to design and build a balloon launched cross-band repeater for search and rescue purposes. He presented this project at the 2017 Dayton Youth Forum. He shares with us the components utilized in the repeater and the processes that he went through to design and build a solution. Rob continues to work with students today and he shares with us the most recent project-a portable solar-powered digipeater meant to handle text-based traffic in remote disaster areas with no infrastructure. Along the way, Rob also shares some of his tips on how to get youth interested in amateur radio.

In this episode Mark, Vince and George interview john KC9ON about kit building.  John has extensive experience not only building his own kits but also selling kits through his company on line.  We talk about our projects, favorite kits, and the tools necessary for a successful kit building experience.

We are coming to you live, well recorded live actually, from the QSO Today Academy.  On this episode we are joined by our favorite mega-fan Troy K4JDA and the regular crowd including Vince VE6LK, Thomas K4SWL, Mike VA3MW, Mark N6MTS and host George KJ6VU.  We talka bout all sorts of ham radio workbench related projects and topics.  

The BITX40 is a $60 Arduino controlled 7 watt QRP SSB 40 meter transceiver designed and built by Ashar Farhan VU2ESE.  They are available as a “kit” from http://www.hfsigs.com/ .  The assembly only involves soldering wires for things like speakers, power, and microphones and also finding a suitable case.  We originally spoke about the BITX40 back in Episode 26 (http://hamradio360.com/index.php/2017/06/20/ham-radio-360-workbench-26-the-bitx40-transceiver-an-introduction/)

Mark “Smitty” Smith KR6ZY is back with us again to share with us the modifications and upgrades he’s made to the original BITX40 over the summer.  In this episode, we discuss adding upper sideband capabilities, adding an IF shift, and even multibanding the radio!  Smitty shares lots of great resources and ideas in this episode of the Workbench.

In this episode we meet Pat Hensley, W5WTH, a prolific designer and project builder.  Pat has made several intersting radio and non-radio related electronic projects and he features them on his blog site WhiskeyTangoHotel.Com

Some of Pat's projects are very useful and some are just plain fun.  Many projects are a blend of hardware (Arduinos, Raspberry Pis, etc) and software (c, Python, etc).  Pat publishes all of his source code for us all to learn from.  If you want to be inspired to build your first project you have come to the right place.
