Compiling the equipment to make a complex version of Zello is infinitely more expensive than free.Expensive? If you consider $75 "expensive" then you are in the wrong hobby.![]()

What is your fixation on "Zello" about? What I've been speaking of has absolutely ZERO to do with any such application.Compiling the equipment to make a complex version of Zello is infinitely more expensive than free.





The demise of ham radio is a topic that has been debated ad nauseum here and other forums. It's been beaten to death and beaten to death and beaten to death (as this thread proves.) Isn't it about time this thread be closed and we leave the horse to die in peace?
Yeah, just like Zello. When you reduce your transceiver to just a mic for an internet chat, you get to take advantage of all that it offers. Just don’t confuse it with radio any more than when I use my wireless headset to talk to customers in a GoToMeeting session. Technically it is wireless, sure, but it’s not ham radio. When I Skype or FaceTime someone, technically radio waves are involved, but it’s a license-free and far simpler and cheaper way to accomplish the same internet chat result. Great technology, just don’t confuse it with amateur radio.In the final analysis it is not all that different that any QSO via a repeater; just that this repeater has worldwide coverage!![]()
Back on August 31, Richard VK7ZBX and Rex VK7MO completed the first VK7 to VK7 EME contact over a distance of 720,000 km, even though their stations were only 22 km apart here on Earth. Operations were at 10 GHz using the QRA64 digital mode.
Richard was running a 75cm dish and 60 watts - to Rex running a 113cm dish and 90 watts.
At the time the Moon was nearly as close as it can get, but even so this resulted in a propagation loss of 289 dB!!
However spreading was around 35 Hz producing an additional loss of around 3.4 db. Signals were solid and a degradation test with added noise showed there was 5 dB in reserve.
On the following day the Moon had moved a further 1562 km away due to its elliptical orbit but this cost only an additional 0.1 dB. But the spreading was now down to 3 Hz reducing the overall loss by around 3.3 dB compared to the day earlier. With this extra 3.3 dB in hand Richard tried out a 60cm dish and just 30 watts and again a QSO was completed. This time degradation tests showed there was nothing to spare.
This second QSO is believed to be between the smallest dishes ever to complete an EME QSO with power of just 30 watts at one end.
Critics might ask how we are sure the signal got to the Moon and back rather than direct between us. The answer is that the signal took 2.5 seconds to arrive which relates directly to the time it takes at the speed of light to get to the Moon and back. In addition Doppler shift calculated at around 20 KHz proved to be within about 5 Hz once it was automatically compensated - again confirming the signal was being reflected from the Moon.

You just shot yourself in the foot with that last statement. Those hot-spots do use the internet, which is basically the same as 'Zello'. There's no great harm in using the internet for a 'link', but don't confuse that with 'radio', it isn't. Which I think is the basis for that argument.
I disagree. Considering that you have to have an amateur radio license and use a ham radio to transmit and receive on a ham band in order to talk to other amateur radio operators, using a hotspot sounds like just another area of the broad spectrum that makes up amateur radio. Zellio on the other hand does not require an amateur radio license, does not involve a ham radio and does not involve transmitting on any ham bands.Yeah, just like Zello.

Okay. You are entitled to your opinion, just as I am. Having been licensed since 1957 I am pretty sure I do understand the amateur hobby well enough to know what's "ham" and what's "not ham..."You can try to play FCC rule semantics to your heart’s content. When your “transceiver” is just a substitute for a Bluetooth headset for internet chat, it’s great, just difficult to count as radio.
This begs the question: Why would you want to?Suppose I were to use 20m SSB to connect with a remote transceiver that cross-linked to a DMR radio, which in turn transmitted to a 'hotspot' linked to the internet, and contacted an amateur operator in Italy via his local repeater with his DMR HT, would that not count as "ham?"![]()
I believe it used to be known as "experimentation..." Can it be done? Yes it can, although there may be no practical reason for it, it's great fun for me.This begs the question: Why would you want to?
I don't think so. What is the path for the QSO?-GIX-
