Radioddity Radioddity GD-77

A single-frequency repeater function would we awesome on GD77!

Over a year ago I had the same idea (without knowing that the single-frequency repeater is a hytera function) and I asked the guys that write the MD380 firmware if that would be possible. They quickly said that it's unlikely that the hardware (on md380) is suitable for that, but there was no actual testing done.

Again, no. The radio has to be able to buffer at least one timeslot's worth of bits to encode and decode between bits and audio. 33ms worth of bits is well within the buffering capability of the radio. Any DMR radio could function as a single-frequency repeater, if the manufacturer bothered to add the capability to the firmware.

Okay, I was a bit slow on the uptake, but now I fully understand your point. I'm still not sold on the actual utility of such an arrangement, but perhaps I just don't have enough imagination... :lol:

The ability to deploy a repeater on any desired frequency without the need for an expensive, bulky, and finicky-to-tune duplexer would seem to be an obvious advantage...

 

[greggk]

but is possible in the memories change the numeric frequency in alphanumerics name or not ?


RUMORS say that the collegue "TY" have to me a GF-77 Tools (like the md-230 tools) you have info?


In this moment NOT possible to HW limited put inside the all WW date base of ham radio like the

MD-380 or MD-2017 ?

This would be easier to read if it was in Chinese. African Pygmy. Aramaic.

Honestly, what kind of nincompoop came up with a name like Radioddity let alone is stupid enough to buy a POS like that????

I suppose that if you have a very small area that you need covered it could come in handy. Or, if you can hoist the HT up high in a tree to not quite double the range.

I've had one for months and get great reports from all over the globe.

Someone who can only afford $80.

You could also connect it to a base antenna for better neighborhood coverage.

well I need to ask will this radio work with these frequencies I wanted to validate it would before buying this radio.... rr db entry here:
https://www.radioreference.com/apps/db/?ctid=347
planning to purchase it off amazon as soon as someone confirms it will work with the above frequencies https://www.amazon.com/dp/B0749LHXFQ/ref=psdc_912322_t2_B073JS2CQ2

also it supports rx only right to not violate fcc rules right?

There are a lot of frequencies on that page, but if you are referring to the DMR stuff then yes it will (provided they don't use encryption obviously). And yes, you can do RX only.

yes DMR is what I was interested in.

great radio, i heard some ham-radio and work well good voice !

have see that in china is buy with the label TYT ? i think that this radio is built by TYT

and rebranded by Radiodditty !


NO NEWS about the all WW databse of all the ham-radio on the display like the MD380

retevis Rt3 ??? No, american collegue ( like Trevis good ) that implement the all ww database ?

There is no need for any more updates on that topic. It is not going to happen. They have said this many times. There is not enough on-board memory on the radio to support the entire database.

I programmed all the DMR frequencies in and the green indicator shows it is receiving but I cannot hear anything did I do something wrong on programming it or is there someway you have to program it so you can hear the transmissions?

Do you have the proper timeslots / color code and group code entered? Do you have the group code in an RX Group list and assigned to the channel?

yes I think so this is what I configured for Jackson County Fire Rescue Dispatch Channel

Try pressing the button assigned to the "Monitor" function while on this channel. When you are on a DMR channel this will enter promiscuous mode. This will allow you to hear a DMR transmission using any Color or Talkgroup on the that channel.

 

[ecps92]

Can/Would it display the info from the system being monitored in this mode ?
ie: CC:, SL: and TG: ??

Scan Fail

I have programmed this thing with a codeplug but it will not scan?What am i missing here..I press scan button and scan fail comes on the screen..Help Idiot alert.lol
