Hamvention QSO Party Set for Saturday, May 16

Alan Thompson
 

The Hamvention QSO Party, a sort of virtual Dayton Hamvention®, will take place on the HF bands on May 16, which would be the Saturday of the now-canceled event. “Let’s celebrate the many years we have all had at the Great Gathering we call Hamvention,” said an announcement over the signatures of Tim Duffy, K3LR, and Michael Kalter, W8CI.

“We also want to remember Ron Moorefield, W8ILC, who never missed a Hamvention and contributed to our club until his recent death. Let’s light up the airwaves with our remembrances of Hamventions of the past! See you on the air!”

The Hamvention QSO Party will be a 12-hour event, 1200 UTC until 2400 UTC on May 16. Operate CW or SSB on 160, 80, 40, 20, 15, and 10 meters, exchanging signal report and the first year you attended Hamvention. If you have never attended Hamvention, send “2020.”

Designated members of Hamvention’s host, the Dayton Amateur Radio Association (DARA), will activate DARA’s W8BI. Participants can add 10 points for each band/mode contact with W8BI (12 available). Post scores (number of contacts) to 3830scores.com within 5 days of the event. An online certificate will be available to print. No logs will be collected. N1MM Logger+ has provided a User Defined Contest module for the event. More information is on the N1MM Logger+ website.

Re: Initial success with PAT adapter on FT-857

I think you're right about the sensitivity & noise.  I need to find a way to measure it.  I think the sensitivity returns to normal when I disconnect the rtlsdr, so it might be okay to keep as an option.

Good to hear it installed well! 

Just be sure that the tap doesn't reduce the receiver sensitivity. When installed in the Icom 706MKIIG, the receiver sensitivity was lowered by about 1 S-unit.

Best Regards!

Initial success with PAT adapter on FT-857

KK6WCG - Daniel
 

I mentioned this on the coffee net yesterday.  I got a PAT adapter from sdr-kits.com (huprf) yesterday and have had some initial success getting it working.  I get a waterfall display on the SDR on my computer about 40Mhz wide and it seems like the radio's still working normally.  

Now that I'm starting to feel good about it, I'll go ahead and drill holes in the back of the chassis for a more permanent connector mount.  Just thought I'd share here.

winlink client needs Pat & direwolf. both vhf and hf.

winlink server needs LinuxRMS server and direwolf

Linux AX.25 networking needs to be setup for both.

and yah, I put one in tne truck too!!  SMS and email on the road!

Nicely done!  (And love the beer coasters...)

I've got a Pi-3B hooked to my rig in the car, with Direwolf as the TNC and YAAC for APRS, so now I need to get Winlink running.  Is PAT the only software I would need to add (along with the config files), or is there something else running under the hood?

Interesting that the "new" Retro Encabulator was only slightly improved by Rockwell over the original.

Tower Accident Report

Dennis - WU6X
 

I am writing in response to your request for “additional information.” In block number 30 of the accident report form, I put “poor planning” as the cause for my accident. You said in your last letter that I should explain more fully. I trust that the following detail will be sufficient.

I am an amateur radio operator. On the day of the accident, I was working alone on the top section of my new 80-foot antenna tower. When I completed my work, I discovered that I had, over the course of several trips up the tower, brought about 300 lbs. of tools and spare hardware. Rather than carry the now unneeded tools and materials down by hand, I decided to lower the items in a small barrel by using a pulley, which fortunately was attached to the pole at the tip of the tower. Securing the rope at ground level, I went up to the top of the tower and loaded the tools and materials into the barrel. Then I went back to the ground and untied the rope, holding it tightly to insure a slow descent of the 300 lbs. of tools.

You will note in block number 11 of the accident report form that I weigh 155 lbs. Due to my surprise at being jerked off the ground so suddenly, I lost my presence of mind and forgot to let go of the rope. Needless to say, I proceeded at a rapid rate up the side of the tower. In the vicinity of the 40-foot level, I met the barrel coming down. This explains my fractured skull and broken clavicle.

Slowed only slightly, I continued my rapid ascent, not stopping until the fingers of my right hand were two knuckles deep into the pulley. Fortunately by this time I had regained my presence of mind and was able to hold tightly on the rope in spite of the pain. At about the same time however, the barrel hit the ground. The bottom fell out of the barrel. Devoid of the weight of the tools, the barrel now weighed 20 pounds.

I refer you again to my weight in block number 11. As you might guess, I began a rapid descent down the side of the tower. In the vicinity of the 40-foot level, I met the barrel coming up. This accounts for the two fractured ankles and the lacerations or my legs and lower body.

The encounter with the barrel slowed me enough to lessen my injuries when I fell into the pile of tools, and fortunately only three vertebras were cracked. I am sorry to report, however, that as I lay there on the tools in pain, unable to stand, and watching the empty barrel 80 feet above me, I again lost my presence of mind.

I let go of the rope…

Hope you are smiling after reading this ...

I just purchased the NanoVNA H4.  It’s just over one week old.

 

Mine was shipped with firmware dated Jan 2020.  There is a newer version issued in Feb 2020 that resolves a touchscreen issue.  Highly recommend you up grade right away.

 

If anyone needs a little help, I’ll share what I found.

Thanks Clyde. I'm still not sure which one I want to buy ... I really don't "need" one, but thought looking at 3 to 4 more weeks of self-imprisonment, it might be fun to play with.
