The dark side

Oh my, what have I done

Don't take away my QRP CW card. 


I picked up an old, high impedance Heathkit microphone having the appropriate 2-pin connector.  One pin is the mic line and the other is for the PTT switch. The shield is common.

I set the mic level to indicate some movement on the ALC and peaks were occurring around 100w.  QRP SSB will be tough to achieve.  

I worked a few stations on 80m and they delivered great reports and offered their own stories of Heathkit radios. 

The old rig is certainly a conversation starter.


That's all for now

So... well, my QRP saying doesn't go with this post, so...  warm your tubes and smell the cooking resistors

Let’s Call CQ – QSO Today Episode 184 with NW7US

I got a Skype call a few weeks ago from Eric, 4Z1UG–the creator and host of the QSO Today Podcast–during which he asked me about how and why I got into amateur radio.  Here’s the result.

Eric writes,

We talk a lot about the band conditions due to the Sunspot cycle. Most of it on Facebook and other places is about how “dead” the bands are at this point. We all can’t wait until the cycle starts to rise and we will be making contacts with little effort. I remember in my conversation with Chuck Adams, K7QO in Episode 58, that he really enjoys operating is “Pigrig”, one watt, CW transceiver on 20 meters. When I asked him, (I liberally paraphrase) “but Chuck, the bands are dead. How does that work for you?”. His reply was that while most hams are listening to the bands, he calls CQ until he gets a reply. Works every time.

My QSO this week is with Tomas Hood, NW7US, who has years of expertise in propagation and Solar activity. He is the propagation editor of more than a few radio magazines and websites. In our post-recording conversation we discussed this phenomenon of listening and not calling CQ. I even had this idea that maybe one of the reasons that the digital modes are so successful is because they “beacon”, as part of the whole digital experience, the same as calling CQ. This is why they make contacts. From what I see, looking at PSK Reporter, hams are making lots of contacts worldwide using the digital modes. While SSB may not be working so well, CW and the digital modes seem to work fine.

I like to work on my bench or make the podcast while listening to the bands. Jeff Damm, WA7MLH, in Episode 177, says that he will put his keyer in CQ mode while he is working on a new radio. Invariably, sometimes after many minutes, he gets a reply. Great idea Jeff!

73,

Eric, 4Z1UG

Highlights of Episode 184:

Tomas Hood, NW7US is the propagation editor of a number of shortwave and amateur radio magazines, and has a wide variety of websites, that grew out of his love for all things radio, and for listening on the bands to far off DX and commercial broadcast stations. Tomas shares his understanding of propagation and the lessons we can learn from listening, really listening to the QSOs and exchanges during contest operation.

All of the QSO Today episodes are great.  I enjoy hearing about many different hams.  Do check out all of the episodes that Eric has published.

LHS Episode #208: Ham Radio Logging Deep Dive

In this episode of Linux in the Ham Shack, the hosts take an in-depth look at ham radio logging. Topics include: should you log? What are the most popular logging applications? What formats are available? Should you log to the cloud? Logging best practices. And a whole lot more. We also address announcements and listener feedback. Thank you for tuning in!

NBC Report Features Hawaii Hams Preparing for Nuclear Attack

“In the case of an electromagnetic pulse from a blast, 90% of people may be without communication and ham radio is actually one of the ways that you’ll be able to hear what’s happening.” That’s the report that NBC News correspondent Jacob Soboroff gave just moments after the nuclear all-clear was given during the recent scare in Hawaii.

Check out the great 8-minute video below featuring Hawaiian hams and how they’re preparing for the unthinkable in one of the most beautiful places on earth.

Weekly Propagation Summary – 2018 Feb 12 16:10 UTC

Weekly Propagation Summary (2018 Feb 12 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Feb 12 0146 UTC.

Highlights of Solar and Geomagnetic Activity 05 – 11 February 2018

Solar activity was at very low levels on 05, 08-09 and 11 Feb while low levels were observed on 06-07 and 10 Feb. All of the period's activity originated from Region 2699 (S07, L=165, class/area Dai/240 on 10 Feb). The largest observed event was a C8 flare observed at 07/1347 UTC. No Earth-directed CME activity was detected during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels the entire period.

Geomagnetic field activity was at predominately quiet levels under a nominal solar wind regime. Isolated unsettled intervals were observed on 05, 09 and 10 Feb.

Forecast of Solar and Geomagnetic Activity 12 February – 10 March 2018

Solar activity is expected to be at very low to low levels, with a chance for M-class activity, through 16 Feb due to the flare potential of Region 2699. Very low levels are expected from 17-28 Feb. A return to very low to low levels, with a chance for M-class activity, is possible from 01-10 Mar after the return of old Region 2699.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels on 12-25 Feb, with a chance for high levels on 19 Feb, due to influence from recurrent CH HSSs. Mostly normal levels are anticipated on 26 Feb – 10 Mar.

Geomagnetic field activity is expected to be at quiet to unsettled levels on 15-18 Feb, 20-22 Feb and 04 Mar, with isolated active periods likely on 16 Feb. This activity is due to influence from recurrent CH HSSs. Mostly quiet conditions are expected for the remainder of the outlook period.
