SPECIAL CORONA VIRUS EMERGENCY EDITION

We thought it would be nice to put out a special edition of the podcast to help listeners keep up their morale during this difficult time.  So we’ll do our regular kind of show, but we’ll try to emphasize things you can do to stay busy and keep up morale while stuck at home.

--NOVICE RIG ROUNDUP.  NRR.  Continues through this weekend.  Lots of fun.  Cool rigs worked:  Jon WS1K’s "Scrounger."   Greg AA8V’s 6X2 superhet.  And WN4NRR. 
-- S-38 MANIA.  My S-38E story.   Bought parts.  Bought a junker.  Fixed the first one then used the parts to fix the junker. Now I have 2 S-38Es.

Thoughts on How Hams Can Use the Shortwave Broadcast Frequencies


Ed DD5LP sent us some very interesting information about a resurgence of shortwave broadcast activity in Europe.  Thanks Ed. 

Here is a collection of QSL cards sent out last year by some of these new stations.  

Hi Bill,

I'm just listening to the latest podcast and note your returning lovefor AM Broadcast stations and wondered if you also see the trend in the US that we are seeing in Germany?

 I know you have WTWW but that's a commercial SW AM Broadcast radio station, that has always been owned and run by a family of Hams. What we are seeing Germany is that when a commercial broadcaster such as Deutsche Welle closes down their Shortwave Broadcast stations, Amateurs are applying for and getting licences to the freed up frequencies. This started about 5 years ago with channel292 (Channel292.de) on initially 6070 kHz and then later also  on 7440 kHz. This amateur is located near Ingolstadt in Bavaria and runs 10 kW using the driver stage from the old DeutscheWelle 100 kW transmitter on the same frequency. He is partnered with a group in Austria who run a major AM station near Vienna that has two 500 kW transmitters and some fantastic massive antenna systems with 20dB gain across the whole  of the HF spectrum. That Austrian station is still owned by the Austrian government in case they need a broadcast station to transmit around the world at any time. It's kept "idling" at 100 kW in the meantime and like Channel 292 includes the German language "DARC Radio" amateur radio program in what it transmits.

New on the scene is "shortwaveradio.de" - Yes the station name is the same as their web address. They currently run just 1 kW into an Inverted-V wire antenna on 3975 kHz (in the 75m BROADCAST band over here) and 6160 kHz in the 49m broadcast band.  As they are located in North Germany, I don't get much of a signal from them down here in the south and the recording is using a WebSDR receiver. Their dipole is orientated to cover the Benelux countries and the UK. The lads at this station are always looking for English content, so if you want part of Soldersmoke to be transmitted on a shortwave AM broadcast station, (as you mentioned in the latest podcast) I can easily put you in touch with them.

One more for the list could be Radio Caroline in the UK. The station, which once was the main pirate radio station off the coast of the UK is now a volunteer historic preservation society (with some radio Hams involved) who have been granted a local radio service licence using a frequency (648 kHz) and transmitter site previously used by the BBC world service! Their old nemesis ! (http://www.radiocaroline.co.uk/#home.html )

QSO Today Interview with Dale Parfitt W4OP


Eric Guth 4Z1UG interviewed Homebrew Hero Dale Parfitt W4OP on the QSO Today podcast.   The interview is really great.  Listen here:

Wow, libration fading.  Who knew?  

Dale has appeared in many SolderSmoke bolg posts and podcasts.  He is definitely in the Homebrew Hero category.

The Woz on Technology, Surplus Parts, Intercoms, and Ham Radio



Thanks to Dan Random for alerting us to this.  During the first five minutes Woz talks about being an "electronics kid" and becoming a ham radio operator.  For me also, wired intercoms were a precursor to ham radio.

The Homebrew Rigs I Worked During the First Day of Novice Rig Roundup (NRR)


The Thing-of-Beauty above is "The Scrounger" homebrew transmitter of Jon WS1K. Jon writes: 

The rig I used this morning was the Scrounger.  I built it a couple of weeks ago.  It took me about 2 months of trolling a local thrift store for the right pan. I wanted a pan that captured the spirit of a true Novice built rig.
As a side note, the key that I'm using is a JH Bunnell that I bought at one of the MIT flea markets last summer in Cambridge.  It's mounted on a piece of plywood and written on the plywood is the Novice callsign WN1UMD.  Cool or what?

N2CQR Novice Rig Roundup Station


I actually used that Drake 2-B as a novice back in 1973-1974.   The HT-37 came a bit later. 

For the Novice Rig Roundup I used the beautiful key that Peter VK2EMU sent me.  Thanks again Peter.  

Novice Rig Roundup is a lot of fun.  I was on 40 CW in the old Novice band today.   Worked Greg AA8V who was using a homebrew superhet receiver -- that doesn't happen every day.  Another station asked a question that we don't hear much these days: "What are you running?"  

I will make some more contacts during the rest of the NRR period (scroll down to a recent blog post for more details).  I have my NRR serial number.  Thanks to the organizers for putting together this fun event.

Boat Knack -- Rebuilding a 1910 yacht "Tally Ho"

https://www.youtube.com/channel/UCg-_lYeV8hBnDSay7nmphUA

I present this as part of our occasional series on people with other kinds of Knack.  The young Englishman in this series of videos is definitely in this category.  Watch him acquire the 1910 yacht "Tally Ho" for 1 pound sterling, transport it to Washington state,  SINGLE HANDEDLY  build a boat shed around the huge vessel, and carry out the restoration.  Oh yea, all the while shooting videos of his work. Great stuff.  

I advise you to watch the series from the beginning.   The next video in the series will load automatically. 

Be sure to subscribe the channel. 

Thanks to Ryan Flowers of https://miscdotgeek.com/ for alerting us to this.

N3FJZ's Al Fresco. BITX-inspired, TIA. 50 Watt, SSB Rig (Video)



The last blog postings on Rick N3FJZ were in 2015.  Rick sent me a very uplifting reception report, then we had a pretty amazing Homebrew-to-Homebrew contact.  

Paul Taylor VK3HN yesterday alerted me to a new YouTube video that shows the progress Rick has made with his homebrew SSB rig.   

This is a great example of true amateur SSB construction.  Rick is making use of a combination of digital and analog technology.  He is adapting circuitry developed by others and using it to meet his needs.  During the development stage he is keeping the circuit open (Al Fresco) so that he can easily work on it.  

FB Rick.

Novice Rig Round-Up -- March 7- March 15, 2020


I may go with my Drake 2B and HT-37.  But If I get ambitious (and masochistic) I might try to involve the Hallicrafters S-38E that has been torturing me lately.  And I do have a DX-40 on the shelf... 

Here is the announcement:  


VE7SL has a really nice description of the event with great pictures:

KG7TR Describes his Homebrew SSB Rigs (Video)



We have posted before on the amazing homebrew creations of Mike Bohn KG7TR. 

Today I watched this 54 minute video in which Mike describes his rigs. (Thanks to Pete Eaton, WB9FLW for pointing me to a site that has this video.)    

Quote from KG7TR:  "I have never destroyed a pristine Command Set." 

Wonderful tribal knowledge throughout, especially on the metal work, parts acquisition, front panel work and toroid placement. 

Clear you schedules.   This is really worth watching.
