Simple Remote Radio

Michael WA7SKG
 

I have a need for a simple remote radio. All I need is two-way audio and PTT. No channel control or anything needed. Ideally, something via a web browser as a few of the users have limited computer skills. The user would need to be able to monitor the radio for several hours at a time. This would be used with both FM and HF radios, so the stream to the user may have noise floor audio all the time.

My thought was to use something like a Pi Zero for the purpose, the stream would have to be full duplex and use some I/O pins for the PTT.

The remote user would open a web page in a small window with a clickable on/off PTT button (on a timer for safety) and hot key option. That should allow use with a smartphone or computer.

This is a minimal budget project (aren't they all?) I don't need anything fancy like a RigPi.

Thanks for any ideas or suggestions.

That is the 64 bit version for the RPi. 
Download the ...armhf.deb version for 32 bit OS.

Here in Kansas my friends, we have the Kansas Guarantee-
"If it breaks in Half you get to keep both peaces"

There is a variant that applies to MULES and other animals....

Which brings me to the related Ethnic riddle  which I can tell as my Mother was born in Italy, making me 1/2 pisano.

Lifetime of the product which until it breaks 
And you get to pay return shipping and good luck after that!
Seriously though, DL2MAN has left a video or two on YouTube reviewing the Asian offerings and my impression is that he found the quality and performance seriously lacking. So, probably NOT the best option if you are looking to put together a uSDX???


Re: QDX

Dave Wade
 

Well is the “Lifetime” as in the lifetime of the product or the purchaser. They do say it’s the Manufacturer’s Warranty, so heaven help you talking to them…..

.. as for the “protection plan” I think that’s something E-Bay offer. I don’t see it in the UK…

In addition to the lifetime guarantee you can get a $9.99 “2-year protection plan” .....

Dave and Phil---

Dave - I am mid west- old west and sometimes just don't get it...It's funny though... Good job..

Phil-

Here in the US, people say, "I"m from REALVILLE".. meaning things are simply taken. Especially with CHIN-glish... when it doesn't make sense without further explanation..
I view "independant switchable" different than Stackable.. Thanks for clearing the elderly brain fog,,,

Further- as you are aware we do have problems with the Queens English..(and driving on the wrong side of the road)  Then I heard on the news 2-3 days ago.. an additional 1200 words this year were added to the Webster Dictionary. And we are supposed to be expert communicators..

- Three independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB) - READ IT AGAIN!!!

Stackable 13dB, 20dB, and 40dB attenuators will do that:
0dB
13dB
20dB
13B + 20dB = 33dB
40dB
40db + 13 dB = 53dB
20dB + 40 dB = 60dB
13dB + 20dB + 40dB = 73dB

No need to get stereotypical, Larry. I just mean I haven't seen a transceiver like that before. Undoubtedly because people from Arizona are weird. 73

Dave R and Don W6CZ...

I was told by QRP-labs Hans in an email that it will do RTTY when he emailed me about that.

I am wondering about the QCX variant out of China for $130 on Ebay.... The FREE SHIPPING is $12 and "Lifetime Guarantee" have caused me pause.

Maybe the guarantee is against breaking in half..Like the Kansas Guarantee " if it breaks in half, you get to keep both pieces".
Some Specifications can't be believed:
- Three independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB) - READ IT AGAIN!!!
