Register and join us at the QSO Today Virtual Ham Expo!

8 Comments

The 2023 QSO Today Virtual Ham Expo will be held on March 25 – 26 and I would encourage you to register now.

I have attended every QSO Today Visual Ham Expo since Eric (4Z1UG) created this brilliant virtual event. The online platform is quite easy to use and there are loads of fascinating topics from a wide variety of presenters.

Click here to check out the presentation list.

I applaud Eric for championing radio topics that are open and accessible to Technician (and equivalent) class operators.

Twice before, I haven’t been able to attend the Expo sessions live (due to my schedule) but I register anyway! Why? Eric archives and provides all of the presentations in video format on-demand for Expo attendees after the event has ended. I simply log in and work my way through presentations over the course of a month, one morning coffee after another! The gift that keeps on giving!

These presentations are a shorter format and (I find) focus less on general topics covered elsewhere; they’re truly unique to the Expo.

This is one of the main reasons I register for the QSO Today Virtual Expo: I want to support a platform that produces brilliant ideas, innovations, and encourages a wide radio of radio activities!

I have no idea how Eric puts all of this together, but I’m glad he does and we all benefit from it.

Eric also shared the following preview of the Roundtable Lounge that allow Expo participants to hang out in real time and move from table to table fluidly.

Here is what the Ham Radio Workbench table will look like (20 seats):

I’m really looking forward to this event! I hope you’ll join us.

KU3X Explores IC-705 Current Drain and Battery Packs

Many thanks to Barry (K3UX) who writes:

Thanks partially to your feedback, I purchase the IC-705 and I am one happy camper.

Icom states the current drain on receive for this radio is between 500 and 800 ma. So I tested the radio.

At 13.8 volts of supply voltage, the radio draws 200 ma on receive. What? At 12 volts the radio draws 225 ma on receive and at 11 volts, like off of a 3 cell LiPo battery the radio draws 250 ma.

When I made these tests, I removed the Icom clip on battery. Now going down to 8.4 volts, the radio draws 335 ma on receive.

So here’s the fly in the ointment: At 8.4 volts from the external supply, the radio would not transmit. It would not transmit at any voltage under 10 volts.

Conclusion….. there has to be a boost circuit built into the radio that goes between the battery and the radio. So to boost the battery voltage you will draw more current.

I posted my findings on my web page.

Thank you for sharing this, Barry! Funny enough, I’ve never thought to check current without the battery attached, but that makes sense. This would give us data knowing the radio isn’t using more current to recharge the battery pack at the same time. 

Typically, the lower the voltage, the higher the current drain and vice-versa. Also, I believe you’re correct in that there would be some extra consumption with the voltage booster in play. 

Thanks for sharing this!

DX Commander channel (temporarily?) removed from YouTube

A number of friends and readers have reached out to note that the DX Commander YouTube channel hosted by Callum (M0MCX) has been completely removed from YouTube. 

Callum’s channel is incredibly popular and this removal has everyone scratching their heads, so it’s no surprise there’s wild speculation floating around out there. Don’t fall into that rabbit hole.

I fully suspect that this is simply an error on Google/YouTube’s part and that his original channel will eventually be reinstated. 

In the meantime, Callum has started a second/backup channel where he’s posting content. Click here to check it out.

When his original channel is reinstated, you’ll find it here.

Eric interviews Paul Mower (VA6MPM)

3 Comments

Yesterday, while running errands in town, I listened to the latest episode of Eric Guth’s (4Z1UG) QSO Today Podcast.

Paul Mower (VA6MPM) via QSO Today

In this episode Eric interviews Paul Mower (VA6MPM), a SOTA enthusiast who lives and activates summits in the Canadian Rockies.

It’s a fascinating interview because Paul hikes to incredibly remote regions of the Canadian Rockies and is a member of the Alpine Club of Canada, where he helps to maintain their backcountry huts.

I don’t do the type of trekking Paul does, so it was intriguing to hear him speak about issues with keeping batteries warm in -30C temps and operating in what I would consider extreme conditions.

Click here to check out this episode on the QSO Today podcast website.

Funny: As I started listening to the QSO Today episode, I thought Paul sounded familiar then realized that Paul was one of the presenters of the QSO Today Virtual Ham Radio Expo in August. Here’s that presentation–well worth your time:

QSO Today Virtual Ham Expo this weekend!

Leave a comment

Many thanks to Pete (WB9FLW) who shares a reminder that the QSO Today Ham Radio Expo is this weekend.

I missed the last QSO Today Expo and heard that there were numerous technical glitches. Eric Guth (4Z1UG) has repeatedly described that experience as one of the most stressful in his life. He is making sure that this Expo will run smoothly by keeping all of the presentations and experience on the same platform. Eric is an amazing fellow and has gathered an outstanding group of speakers (over 90, I believe) and has made it so that if you can’t attend live, you can watch the presentations, on demand, for 30 days. Here are a few details from the QSO Today Virtual Ham Radio Expo site:

QSO Today Virtual Ham Expo

Opens: August 14th, 00:01:00 UTC or August 13th, 5:01 PM PDT

  • Full Registration is $10.00 US – includes full access to the Expo, including presentations, 12 subject video lounges,  and to the 30 day on demand period.
  • Full registration will increase to $12.50 at the door when the Expo opens.
