Radio Reviews, Questions and Comments. / Xiegu g90 20w qrp
Last post by vy2js - January 23, 2020, 03:32:14 pm
I think I have settled on the Xiegu G90 as the radio i will start with.  I haven't seen any serious negatives brought up in any reviews.

Power consumption seems pretty good for what it is (i know there is no pleasing Gil on that front haha ) and it puts out full 20W power down to 9v input in videos I've seen.

Very wide ATU that works fast.  SWR spectrum scope, waterfall, SDR... not sure what else i could ask for.

Anyone here use one?  I searched and found no mention of it.

It should be simple enough to use as my home station,  portable rig and even a mobile in my Jeep...

Since my previous post (21-06-2019), there is one update at http://qrp-labs.com/qsx.html:

QuoteUpdate 20-Aug-2019: I know this is taking longer than expected, but there are still a number of details to sort out. I do not want to release it before it is properly ready. It needs to work perfectly first. It's a huge complex project... so please bear with me, patiently...

General Discussion / LoraWAN role in prepping? vs A...
Last post by Drls - January 11, 2020, 10:44:00 am
I'm thinking of setting up a node with
https://www.arednmesh.org/

While researching this, I started to also learn about LORA

I did a search for this forum and on youtube and find very little about use of LoraWan for prepping and communication in emergencies
https://lora-alliance.org/about-lorawan
https://en.wikipedia.org/wiki/LoRa#LoRaWAN

I know that this is typically thought of for other uses... but it is inexpensive, uses low power, portable, and seems like it could easily by a text-message option.  It doesn't even require a HAM license to use...

I'm just learning about this, and figure that there are many smarter here.
Thoughts?

Morse Code / Re: Waiting for a Norcal 40!

Quote from: gil on January 09, 2020, 05:19:35 amThe Norcal 40, precursor of the Elecraft K1, was designed by our member Wayne, co-founder of Elecraft; or was it K8IQY? I can't remember.


Quote from: undefinedThe club is probably best known for its many kits, which started with the NorCal 40, designed by Wayne Burdick, N6KR, that is credited with giving the club a huge boost when we were getting started. Wayne later designed a couple of other famous kits for us, including the 49er and the Sierra.


QuoteNews
The following are the most recent events of the Northern California QRP Club.
November 23, 2004:
Added the 49er construction manual to the manuals page
Also added the K8IQY Iowa QRP 10 Transceiver to the Projects area.

Morse Code / Waiting for a Norcal 40!
Last post by gil - January 09, 2020, 05:19:35 am
Hello.

Great news (for me), I found a Norcal 40A kit on Ebay! It isn't sold as a kit but as a PCB with a bag of components. I call that a kit, but oh well. The Norcal 40, precursor of the Elecraft K1, was designed by our member Wayne, co-founder of Elecraft; or was it K8IQY? I can't remember. The PCB files were released in the wild and some people made runs of the board. A club in England put a kit together for its members and apparently had some left over... I don't know if they have more but a quick search on Ebay for "Norcal 40" will answer that question.

The Norcal 40 is a single band CW transceiver with the amazing receive current of 15mA! Power output is around 2.5W, drawing around 200mA. It will run seemingly forever on most battery packs. It is in the same category as the Small Wonder Labs SW+ from Dave Benson.

There will be a video of course, if it works, and I don't see why not...
Anyone here has used one before?

Gil.

Antennas / Re: EFHW observations and radi...
Last post by gil - January 08, 2020, 06:21:04 am
Hello. I made a lot of great contacts from Florida to Eastern Europe using a PAR 10/20/40 end-fed half-wave hanging vertically, including one to Estonia using 1.3W. Stateside contacts fell into a 800 to 1300 miles radius... I had very few contacts with Western Europe. Not much success between 50 to 800 miles, though Ray and I had almost daily contacts at 820 miles.

I observed the same thing here in the South of France: Easy contacts to England, Germany and Eastern Europe, all around the same distance; nothing to, say, the Paris region...

My EFHW 40 meter picks up 80 meter pretty decent, however it definitely is not resonant there.  Thinking swr more a factor for tx than rx.
