Testing TG 100 Parrot question
DIR By: N1KK
Date: April 29, 2019, 10:12 am
---------------------------------------------------------
There are many times I will test on Parrot on TG 100. Watching
my pi star dashboard I can see
BER of less than 1% with 0% Net Loss. However the reply Parrot
will not contain any audio of my transmission.
I will repeat the process and there will be audio. Other times
maybe half or less of my Parrot test
transmission will be missing words, for example.. Test 12345
and only 4,5 might come back.
My experiences appear to be random.
Prior to my Parrot transmission I check to make sure my hotspot
is not transmitting showing no signal strength
on my HT. This is also confirmed by the Pi star Dashboard.
Could this be nothing more than a network issue? My pi star is
connected via WiFi to a 300 down
30 up WiF. The MMDVM I have uses a Raspberry Pi zero w board.
Radio board is what you find on ebay
STM32-DVM/MMDVM_HS - Raspberry Pi Har (GPID) firmware HS_Hat:
v1.4.16
The Pi Zero on the Admin Dashboard screen show Pi Zero W Rev.
1.1 (512MB)
Kernel 4.9.35+ CPU Load 0.75/0.77/0.86 CPU Temp 38.5 C /
102.2 F
When using my HT on a repeater (no hotspot in use) I have not
had any drop out issues including
using the repeaters Parrot TG.
Any thoughts?
Thanks,
Ken

I've noticed the exact same behavior when using the TGIF Parrot,
so I'm inclined to believe that it's a server side issue rather
than anything we're doing.
I've tested using both standard high speed Internet and cell
phone tethering with similar results: Sometimes I'll get perfect
playback, but the very next transmission will only give back
partial audio.

Bingo,
You described my exact experience. As long as I am good at my
end I am happy.

Do you get the same results with 9990?

That was one of the first things I tried, and yes, it exhibited
exactly the same behavior.

Phil helped me out with this on the DMR Gateway. Here's what I
wound up with. It appears TGIF is sending Parrot back on TG 9990
so the SrcRewrite on 100 may not be necessary.
[DMR Network 3]
Enabled=1
Name=TGIF_Network
Id=xxxxxxx
Address=tgif.network
Password=passw0rd
Port=62031
Local=62033
TGRewrite=2,500001,2,1,99999
PCRewrite=2,500001,2,1,99999
SrcRewrite0=2,100,2,100,1
SrcRewrite1=2,9990,2,9990,1
Location=0
Debug=0

Thanks for that, Moe. I'll try those rewrite changes later
tonight, see if it alters the behavior any, and report back.

Well, this is interesting. I ran several tests on both 100 and
9990 and they were ALL perfect...without making any of those
changes!
The only difference I can see between the tests I made
previously and the ones I did tonight is in the number of active
talkers on the network. This evening, that number is fairly low
compared to the previous times.
So...maybe overall network activity is somehow a factor in all
this?

I'm glad it's working for you without the changes... at least
with low activity It never did for me.
As busy as TGIF can get, I'm migrating to duplex (once it gets
here), giving TGIF Time Slot 1 per this thread:
HTML https://forum.pistar.uk/viewtopic.php?f=5&t=1154
I'll see how Parrot works with that configuration.

I tried this this morning and had the same problem. So far this
random but happening more than not.
