Radio Reviews, Questions and Comments. / Re: ELAD FDM-DUO Transceiver
« on: August 31, 2017, 12:41:36 PM »
Summer is soon over, and I finally decided against buying this fine radio, even at the 25% discount.

Main reason: I don't (yet) fully understand this SDR-stuff, and feel I don't need it (yet).

On top of that, ELAD delivers PC/Windows-only solutions, and I have used Mac only on a daily basis since 1989.

The transceiver used in there is a Hendricks PFR-3A, and I wanted to know more about it:

First: Interesting background on the PFR-3:

These are about the PFR-3A:

Seems the current version is Hendricks PFR-3B, which I found here:

Funny site but very annoying popups that were impossible to dismiss until I gave them a fake email address.

Thanks cockpitbob for the picture, I have seen it a few years ago, this time I stored it for future reference.

… I assume they are in the U.S., but I can't find where they are located.

I also wondered about that. This is what I found out. The owner of QRP Labs is a British ham:

G0UPL Hans Summers. — Email: hans.summers@gmail.com

Check Podcast Episode #125 here:

As a 2009 QRP ARCI Hall of Fame inductee - Hans Summers, G0UPL, is an electronic experimenter and amateur radio innovator extraordinaire. Hans pays careful attention to compact and minimal parts count to achieve the design goals of his homebrew projects. Hans is the owner of QRP Labs joins Eric, 4Z1UG, in a conversation about QRSS slow data transmissions, high altitude balloon transmitters, and shares his ham radio and electronic builder story.

General Discussion / U.S. Navy unit discovers HF radio communications
« on: August 17, 2017, 10:26:14 PM »

The Commander of Task Force (CTF) 75, Fleet Combat Camera Pacific (U.S. Navy), has recently discovered that HF Radio across the Pacific actually works …


Commander, Task Force (CTF) 75 successfully completed communications systems tests using high-frequency (HF) radio waves to broadcast voice and data 6,050 miles from Naval Base Guam to Port Hueneme, California, July 27, 2017.


The assessment tested the capabilities of expeditionary forces to use HF waves to deliver data over the Pacific. HF has become a viable alternative for military forces when more common forms of communication, such as satellites, are unavailable.
[…]
Common communication devices used by the U.S. military incorporate satellites. CTF-75 has been testing HF systems in the case of satellite communication failure. HF is a frequency wave broadcast that is transmitted around the curvature of the Earth. Unlike other forms of frequencies, such as very-high frequencies and ultra-high frequencies, the transmission is not distorted by terrain or physical obstructions.


“We may not always have access to operational equipment or the latest assets, but as communicators we should have a backup plan that is ready to be executed,” said Carmon.


Well done, boys! — Next: The Wheel. And then: Gunpowder …

Sparks, where are you located? Is your BALUN a 4:1 or 1:1 type? You would use it to feed a dipole or Windom.. Do you have two support points high up to string a wire, only one? None? Trees?


Thanks to the three of you who have replied. Sorry for not responding until now! Life's unforeseen circumstances and family responsibilities forced me to leave the radio and the paraphernalia packed and stored with a friend in southern Norway, until further notice, so I haven't been able to look closely at the balun. I planned to use the set for portable QRP (CW only) on hiking trips in forests and mountains. I now consider selling the FT-817ND and instead acquire this radio:

Radio Reviews, Questions and Comments. / ELAD FDM-DUO Transceiver
« on: August 13, 2017, 12:39:06 AM »
I cannot find this Italian radio mentioned anywhere in this forum. Anyone here familiar with it?


I am asking because Norway's major ham outlet runs a summer sale with a 25% discount on this one, and I am considering selling my unused Yaesu FT-817ND to acquire the ELAD FDM-DUO instead.


Some links concerning this radio, mostly reviews:

All my ham radio gear is into this 5.11 moab 6 backpack, leads, rig, antennas, batteries, solar pannel, chargers etc.

(My emphasis.) There is a large empty space after this sentence and before the two concluding ones, but I see absolutely no link(s) nor pictures or any other kind of illustration in between.

And loosing a week with the evacuation oder because of Oroville Dam has put me that much further behind.


Many facts here, hopefully all correct: https://en.wikipedia.org/wiki/Oroville_Dam


And this is Wikipedia at its best: https://en.wikipedia.org/wiki/Oroville_Dam_crisis


This topic interests me since many friends and relatives live downstream of huge dams in Scandinavia.

Update: "Complete kit v 0.6 is in stock" as of March 12, 2017: http://www.m0nka.co.uk/?p=5747

Check main page for "Complete Kit v 0.6 Assembly Error", etc.: http://www.m0nka.co.uk/

A local ham friend of mine just announced on Facebook that he will be building one, that's how I became aware of this kit.

Also, the captchas on this site seem excessive.

I remember I thought so, too, when I was new here. However, I think they disappear when you have posted a few times, ten maybe?

The PRC-320 Yahoo group uses WhatsApp for impromptu skeds.. I don't like the privacy implications but it works.. I'll post something about it soon..

As a Mac user, I was recently warned about using WhatsApp (maybe more things are called WhatsApp, but here goes):

I love when people reply without reading the articles or watching the videos.
The very first example is LINUX BASED!!! :D
I updated the image to show.
I totally agree with you Windows has no place in emergency communications. Android is an excellent lightweight, low current draw solution, when rooted with bloatware removed. Apple? Well everyone has an opinion :D
Thanks for the feedback

Sorry for not noticing this! (However, Linux is even more Greek to me than Windows and Android already are.)

The MiniProSC is Plug and Play on Android Linux and Windows systems.
