TYT Works, Anytone Doesn't

Post by kb0rxc »

Running Pistar on a generic MMDVM hat purchased from Amazon. I have been using a TYT MD-UV380 and it's working fine but I recently bought an Anytone AT-868UV and I can't seem to get it to work. The Anytone does work on a local DMR repeater so I don't think the radio itself is totally broken. I'm new to DMR so I'm assuming that I've got something set wrong. I went over the channel configs several times thinking that I must have fat fingered some number or have a setting wrong and I am just not seeing it so I thought I'd post here and see if anyone else can spot something or give me some advice.

These are the logs from the Pistar, it looks right when I key up the TYT on the BM Parrot TG but when I key the Anytone it doesn't show anything.

These are my CPS settings for the TYT:

And for the Anytone:

Thanks in advance for any help you all can give me!

I'm not sure how either of those would be working. Hotspots typically use SLOT 2, unless you have a duplex (repeater) hat. Those channels are configured for SLOT 1 -- but the log shows the hotspot using Slot 2!

Make sure the TalkGroup for Parrot is configured as PRIVATE CALL, not Group Call.

Make sure the DMR ID associated with KB0RXC ID matches (especially if the hotspot is set for "private"). NOTE: I don't find your callsign in a recent download of the DMR ID database, although Brandmeister shows you having TWO hotspots, both on the same frequency but using different masters. You have FIVE parrot calls on base hotspot, and NO calls on the xxx02 hotspot.

From your log

Code: Select all

M: 2022-06-07 13:14:42.037 DMR Slot 2, RF voice transmission lost from KB0RXC to 9990, 1.1 seconds, BER: 8.9%, RSSI: -77/-74/-75 dBm
Which ever radio generated that entry is showing a rather high Bit Error Rate. You may have to tweak the MMDVM hat frequency OFFSETS (Expert menu) to find a compromise that is happy for both radios. Note that if you have both radios "on" when hitting the parrot you should 1) hear your call to the parrot on the non-transmitting radio since they are both using the same frequency (need to make sure they don't cause feedback) and 2) hear the parrot response on both radios. If the parrot is somewhat garbled on on receive, it is a sure sign you need to tweak the hat offsets.

Look at ur posted log.
Look specifically at the BER value its indicating 8.9% is way to high an error rate for the install to wirk correctly.

You need to get the BER rate down pref <1.0 by adjusting rx offset.

Thanks for ur response - that is the radio that is working though - or at least connecting to the hoptspot. The other radio as I mentioned doesn't even show up in the log.

I have been using the TYT on Slot 1 and it's been working, I tried flipping the Anytone to Slot 2 and it had the same result but I will set them back to Slot 2 to eliminate that as a possibility.

It is.

Searching for my call on RadioID it does show up with my ID number. I flipped the hotspot off of Private mode also just to make sure. I do have another hotspot but it's in YSF mode right now and it's 1MHz off of the other one.

I will work on tuning the BER, my hotspot is in my computer workbench area and there may be some interference from other electronics running in there.

Thank you for all of your suggestions! I appreciate your time.

With the channel set to slot 2 on both radios, and (maybe use a headset on the Tyt to avoid feedback) keying up/speaking into the Anytone, do you hear yourself on the Tyt? If you don't, you may have more significant problems (you may have to try with them configured to something other private call Parrot -- maybe TG9). Also try keying the Tyt while listening to the Anytone. Might even turn off the hotspot for this test. All you are trying to confirm at this point is that the frequency/color code/time slot/TG are the same between the two radios. Since the Tx and Rx frequencies are the same, each radio should be able to trigger the other's receiver. If you can not get each radio to trigger the other, there are no hotspot changes to make -- the problem is in the radio(s).

A simplex hotspot knows nothing of slot1 or slot2.

Duplex hotspot, yes it makes a difference but no difference with a simplex setup.

Probably, after you fix the BER on the working radio, the Anytone may work. Anytones are touchy and like things just so.
