N40NC ORIENTAL REPEATER SETTINGS CHANGE ON FRIDAY, MARCH 25TH
Midmorning March 25th, our new N4ONC 2M repeater will begin a period of
testing on-air. The new machine will operate with dual modes, analog FM
and DMR. First tests will be to ensure analog FM compatibility, and once
tuned and proven we will start DMR testing. If you make minor
adjustments to the radios you have always used with the old machine, you
should see little difference with your FM usage of the new repeater. At
least that’s the expectation at this point considering we have not
tested it ‘in the wild’ among daily users yet.
The DMR side will participate in the NC4ES network, which currently
links 16 machines in Eastern NC, intended for emergency and contingency
communications serving hospitals and emergency management.
The new machine will use CTCSS, or PL tones, on the analog side to
determine which mode a user intends. If it hears a transmission using
88.5 PL, it switches to analog FM mode, services the conversation, stays
in the mode for twenty seconds, then drops the mode until reset by a new
call. If it hears a digital signal without a PL, it switches to DMR
mode, etc.
Analog FM settings of your radios should be as follows for compatibility:
Repeater output (your RX): 147.210 MHz
Repeater offset (change in frequency to your TX): +600 Hz (set your TX
to 147.810 MHz)
Encode PL: 88.5 Hz (sensed by the repeater and allows you access)
Decode PL: 88.5 Hz (sensed by your radio to open your squelch so you can
hear the repeater)
UNLIKE CURRENT N4ONC SETTINGS, IT IS IMPORTANT THAT YOUR ANALOG FM RADIO
BE SETUP WITH THE DECODE PL. WITHOUT IT, YOU WILL HEAR DMR USERS’
BUZZSAW-LIKE SIGNALS WHICH CAN BE ANNOYING AND UNPLEASANT!
DMR users’ channel setup should follow these settings:
RX: 147.210 MHz
TX: 147.810 MHz
CC: 1
Channel Type: D-digital
DMR mode: repeater (not simplex)
Set TS and TGs according to the lineup on the NC4ES dashboard at NC4ES.org
Before the 25th, please add a new memory to your radios for FM use with
the new repeater. If you’re unable, after the PARS meeting on March 26,
a small team of us will help you in an Elmering workshop session. Please
try to do it yourself before the meeting! We won’t be able to reprogram
everyone’s radios if more than a few need help. Bring radios, radio
manuals, and programming cables for your radio, and we will get you going.

SOLAR NUMBERS TODAY
NOAA reported that solar activity was at low levels during the 24 hour
period ending yesterday at 5 p.m. local. There are 4 numbered sunspot
regions on the Sun facing Earth this morning. The Prediction Center
expects solar activity to be low today through Wednesday. There is a
chance (1 in 4) for M-class flares each day. On Sunday the observed
Solar Flux Index (SFI) at Penticton was 123. (Last Sunday it was 116.)
The index is predicted to measure 120 at noon today and again on noon
Tuesday then 115 Wednesday. The SFI 90 day trailing average is up two to
110.
The Earth’s geomagnetic field reached major storm levels yesterday. For
our middle latitude, NOAA expects conditions to be unsettled to minor
storm level today and Tuesday and then quiet on Wednesday. The estimated
Kp-index of 2 reported at 5 a.m. local this morning indicates quiet
geomagnetic conditions.
We can expect fair day and good nighttime operating conditions today on
80 and 40 meters and good day and night on 30 and 20. Conditions will be
fair on 15/17 and poor on 12/10. In sum, no change from last Monday.
DxMaps is reporting significant E layer skip in Western Europe at 1 pm
in the afternoon, while North America is seeing all meteor scatter or
tropo propagation on six meters at 7 am. It is very early for our Summer
Es season to begin, but it might be worth starting to check FT8 on 6 to
see if there’s life.

excellent article written by Carl Luetzelschwab, K9LA at
