This $350 transceiver from Odessa in Ukraine looks very interesting and affordable to me.

• "This is a small-size 10 band short-wave QRP transceiver."
• "The transceiver has small dimensions of 100x103x30 mm. and a light weight of 430 grams. It will suit both for work on the field trip, on nature, at the dacha .... So for everyday work, at home."
[…]
• "Power supply voltage: 9-14.8V (Rated supply voltage 13.8V)".
• "Consumed current in the "RX" receiving mode and 25% loudness: ~ 120mA. At 100% loudness: up to  ~ 250mA."

— They say nothing about batteries — so what would be an optimal battery taking this set for hiking in the mountains?

Also, any comment, such as user experience, will be valuable to me.

Morse Code / Re: CW Operators needed ...
« on: April 29, 2019, 11:14:04 PM »
An interesting thread has shown up on the SKCC Google Groups mail list.

That Google group is history by now (my bolding):

The Straight Key Century Club is the fastest growing group of  straight key Morse code operators and enthusiasts in the world. Organized in January 2006 the club has thousands of members around the globe. This Groups.io group is a meeting place for general discussion by SKCC members of all topics related to manually keyed Morse code, including mechanical bugs and sideswipers. It is the successor to the Yahoo SKCC group as of September 2017.

Antennas / Re: Ground Tuning Unit.

If someone could turn it into a PDF and email it to me: gil@thisdomain.com (switch thisdomain.com for radiopreppers.com). I can only open it on my phone but not my Mac...

I just emailed you the requested PDF (12 pages), converted from DOCX to PDF, made by my MacBook Pro using Microsoft Word.app from Microsoft Office Home and Student 2016 for Mac suite.

Afterwards I discovered that a somewhat earlier version is available online at this URL:

https://www.vk5pas.com/uploads/1/3/9/8/13982788/-guide_to_building_a_portable_station_complete_with__gtu__1_.pdf

That one is signed: "Alex, VK2HAS", while the one I converted ends with: "Alex, VK2HAS now changed to VK2PRC". However, they both begin thus: "Date: 06.02.2016 —  By: Alex Ball VK2HAS".

BTW, there are several more or less free online services to convert from DOC or DOCX to PDF, here are the five top hits in my Google search:

https://smallpdf.com/word-to-pdf
https://www.ilovepdf.com/word_to_pdf
https://www.freepdfconvert.com/
https://online2pdf.com/doc-to-pdf
https://convertonlinefree.com/

I have used the first one earlier, when in a hurry, and I just tried it with your DOCX. It worked fine, except it downloaded with about half the size of what my Word.app yielded. I guess this matters only if you need high quality printouts.

Morse Code / Morserino-32 — a new multifunctional Morse code machine
« on: October 29, 2018, 09:03:50 PM »
Morserino 32 is a new multifunctional Morse code machine specifically built for anyone wanting to learn Morse code or improve their Morse code skills. Watch the demonstration video below to learn more about the system which has launched by a Kickstarter and already raised its required goal with still 12 days remaining on its campaign.

The development team behind the Morserino 32 explain more about its creation and features.

“This kit will change how people learn and practice Morse code. Based on a previous device (the MetaMorserino) and on the experiences of CW Schule Graz, Morserino-32 features a number of functionalities that are, in its combination, unrivalled by any other morse code practice device on the market”

– CW Keyer
– Code Generator
– Echo Trainer (repeat what you hear)
– CW Decoder (from a straight key or from audio input)"
– CW Transceiver, using LoRa in the 70cm band“

It comes with capacitive touch paddles, so you can start learning and practicing without the need to buy an expensive mechanical paddle. But of course, once you have learned the basics and are on your way to the High Speed Club, you can of course connect your favorite mechanical paddle.”
