GB3TD Audio level intermittent issues
Over the past few days it has been observed that the audio level on TD can, on occasions be much lower than it should. Please do NOT adjust your radios or think that your deviation level is wrong as its more likely the repeater.
We are trying to identify the issue but like most intermittent faults its not aways happening when you investigate. We "think" it happens more often when the TX radio gets warm but this is yet to be confirmed.
Please bare with us whilst we attempt to resolve this matter.

GB3TD Frequency Regression
It is with regret that the GB3TD repeater will be returned to its original frequency configuration 433.075/434.675MHz during the afternoon of Wednesday 30th Oct.
The RRG apologise to those that have already reprogrammed there radios however this regression is required to overcome some issues that have been experienced over the coming week.
This will be a short term fix whilst we discuss options with the Repeater Management Committee.

GB3TD Frequency Change from 18th Oct. - **** Action is required.****
Please be advised of the below frequency change notification for GB3TD. To complete this on Friday 18th Oct the repeater will be off-air from approx 1pm. We expect service to resume on the NEW frequency from 3pm
GB3TD Frequency Change
GB3TD Frequency Change
The Swindon UHF repeater GB3TD
has been operational on the same frequency 433.075 Mhz and from the same site
since 1994 and is managed by the Ridgeway Repeater Group.
In recent years the repeater has
been suffering from interference in the form of clicking and pulsing noises and
also from wideband transmissions which can severely desence incoming signals.
The group has spent many hours
trying to determine the source of some of these without success.
OFCOM were consulted and tried
their best to identify the problem without actually finding it due to
restrictions gaining access to certain areas of private property.
The main interference to our
secondary use band is from 433Mhz to 435Mhz which emanates from low power
devices but also the MOD which is the primary user of the band.
When GB7TC our DMR repeater was
commissioned and co sited with GB3TD and using the same antenna, the filtering
system was complicated and caused extra losses in the system. Never the less
has worked well.
A question was asked to the RSGB
repeater committee asking if a 7.6Mhz wide band split would be possible for
GB3TD.
The RRG were asked if the group
would like to try a reverse shift to the normal Tx low Rx high configuration.
GB3TD output frequency will be
438.4375 and the TD receive will be 430.8375.
This was agreed and an NOV issue
to Rob, G4XUT.
The benefit is that the filtering
for GB3TD and GB7TC will be easier with less through losses with both Tx and Rx
being at the same ends of the band.

Monitoring the DMR network
Local monitoring of GB7TC
This shows who is using GB7TC, by following links you
can monitor an individual call sign or switch to other DMR repeaters.
Monitoring the UK DMR network
This show the status of the UK (and some Dutch) DMR
repeaters, also the traffic on the links to Wires and Brandmeister networks.
I use it to monitor and also see who is active!
Checking the internet link from GB7TC
If
you use the echo TG9990 and it fails to echo audio, then the link is down or there
is a core issue. In most cases this will resolve within a few minutes as the
link from GB7TC to the internet uses 3G technology and it reinitialises
occasionally.
GPS to APRS
For those getting to grips with GPS
to APRS. There are a few different private talk groups you can send the
data to which produce different behaviour on APRS.
RRS & Radio IDs:
5050 = without SSID
5055 = House QTH
5056 = Camping
5057 = walking with
handheld radio
5058 = boat
5059 = car
Please see http://www.opendmr.net/index.php/anytone-d868uv-gps/
for set-up and configuration details.
