Well, the New Britain line is only a few miles from here, so you
will be within about 5 miles or so. If you contact tzimmer@arrl.org
and ask for a set of directions, she can get you from there to here.
We are open for visitor tours M-F, 8-5 eastern time. If you are
only going to be here on a weekend, the main building is closed, but
W1AW is open for visitors from 1 PM Saturday, and from 4 PM Sunday.
After 4, the bulletins are running, so guest operation ceases.
If you can only make it here on Sat or Sun, give me a call in advance.
Most weekends I can drive on in and give you a private tour of the HQ
main building. With many of the offices closed and locked, it is not quite
as fun as during the week, but I have a key to the Lab, so you will get
to see some of the highlights.

I will point out that posting to rec.radio.amateur.misc is not the

contact ARRL directly rather than rely on the correct staffer

To: info-hams@ucsd.edu
Good morning. It's Sunday the 3rd of April and here is the GB2RS news
broadcast, prepared by the Radio Society of Great Britain.
First the headlines:- Amateur radio is featured on children's TV on
Thursday; space station Mir can be heard on two metres, channel S22; and
poor propagation is forecast for the coming week.
Amateur radio will be featured this week on the BBC TV series "Why Don't
You?". The broadcast, which is scheduled for 9.30am next Thursday the
7th of April, is primarily aimed at young people aged around 9 to 14.
The amateur radio feature is approximately six minutes in length and
presents the hobby as modern and exciting, and features everything from
crystal sets to packet radio. Members and friends of Rishworth School
Radio Club, in Yorkshire have been heavily involved in making the
programme.
Users of two metre channel S22, 145.550MHz, are reminded that this
frequency is used by the amateur radio station on board the Russian
space station Mir. There are five orbits each day and the window for
contacts with the UK lasts about ten minutes. You may be asked to move
from this frequency, or to stand by, for a few minutes to allow these
space contacts to take place, and your cooperation would be very much
appreciated.
The newly formed group of educationalists, STELAR, which stands for
Science and Technology through Educational Links with Amateur Radio,
will be running a four day residential course this week. The course is
for teachers from schools with no previous amateur radio links. During
the course, which is sponsored by Trio-Kenwood UK Ltd, a special event
station will be active using the call sign GB2SR. It will be on the air
on the evenings of Monday the 4th, to Friday the 8th of April inclusive.
Check for SSB on or near the following frequencies, 3.766MHz, 7.048MHz,
14.165MHz, 21.287MHz and 28.428MHz The station will also be active on
packet radio, and messages for demonstration purposes would be welcome
at GB2SR via GB7MSW on 144.650MHz.
The RSGB's Senior Novice Instructor for Dorset, Phil Mayer, G0KKL has
changed his address. He now lives at: 16 Haig Avenue, Canford Cliffs,
Poole, Dorset, post code BH13 7AJ. His telephone number is 0202 700903.
All enquiries from Dorset Novice Instructors should be sent to G0KKL at
that address.
Attention RSGB members in Norfolk: A new RSGB Liaison Officer (RLO) has
been appointed for Norfolk. He is Bill Higgins, G3PNR, and his address
is 65 Hayden Court, Eleanor Road, Norwich, Norfolk, NR1 2RG. Bill's
telephone number is 0603 629150. RLOs hold a wide range of information
and they are available to help any RSGB member seeking advice.

You're right about the terminology. I do think that Gary C's original
post was refering to people trying to use his repeater through cross
band repeaters, and then Gary McD used the term remote base which I
unconciously translated to cross band repeater. Maybe Gary McD can
restate his question. I will now repeat to myself "Read every
word...Read every word..."

Cellular phones have three advantages over 2 meter remote base stations:
1) They operate at higher frequency. This cuts down the size of a duplexer
quite a bit.
2) They operate at a *much* greater frequency seperation between receive and
transmit: 45 MHz, which is roughly 5% of the transmit frequency, as opposed to
600 kHz, which is roughly .4% of the transmit frequency. This means that the
cellphone duplexer doesn't have to be as effective, which means that it can be
smaller.
3) Cellphones operate at much lower powe, which makes the duplexer's job
easier still: it doesn't have to provide 60-70 dB isolation between receive
and transmit in the first place.
The original poster's comment was quite correct.

Since you refer to small size, I guess that by "this" you mean the
duplexing. The difference is that there is never an overlap between the
transmit band and the receive band in cellular. There is also a channel
TX/RX spacing of 45 MHz (about 5% of center frequency), and an isolation
band 18 MHz wide between the TX and RX bands. OTOH, the duplexer I
refered to above would not only have to deal with our much smaller TX/RX
spacings (0.6 MHz at 146 MHz, about 0.4%), but also the situation
where one time the radio may be transmitting on e.g. 147.60 and
receiving on 147.00, and the next transmission may be transmitting on
147.015 and receiving on 147.615. Thus there is no dividing line
between potential transmit frequencies and potential receive
frequencies.
Anybody out there who knows about cellular circuitry might tell us
whether cellular duplexers are generally fixed or electronically tuned
(maybe on the receive side only?).

pence per minute at cheap rate and 49 pence at all other times. Full
details of the GB2RS transmission schedule can be found in the latest
edition of the RSGB Call Book.
And now the solar factual data
The period from the 21st to the 27th of March, has seen only a very slow
recovery with solar activity very low in most parameters. No flares have
been reported, but magnetic activity, though considerably reduced, is
still very unsettled. The only event of note during the period is the
continuation of the stratospheric warming which now covers central and
southern Europe extending to the pole at levels above 10 hecto pascals,
about 30 kilometres. Sunspot indices have meaned about the 41s, not
varying much day to day. The solar flux has also been almost steady and
averaged 90 units. The 90 day mean flux on the 25th was 105 units.
The geomagnetic activity levels have declined but the passage of coronal
holes is still keeping geomagnetic levels very unsettled, the Ap indices
were up to sub-storm levels of 27 units on the 21st, but had declined to
just unsettled levels of 12 units by the 27th, giving an average of 17
units for the period. The state has been 'Strat Warm' throughout the
period with otherwise nothing to report. We have now caught up with the
aa indices, so here are details for the 8th to the 14th of March. Due to
the passage of coronal holes, levels on the 8th to 12th were up to
'storm', with periods up to 115 nanoTeslas, K6. The daily averages for
the period were 60.2 nanoTeslas, about K4. The period from the 15th to
the 21st has seen the magnetic disturbances decline from a daily level
of 60.9 nanoTeslas on the 15th, to 23.2 nanoTeslas by the 20th. The
weekly average was 40.4 nanoTeslas, about K4 'just unsettled'. The X-Ray
flux levels are slowly recovering and rose from A5.4 on the 21st up to
B1.0 by the 25th. They declined again to A6.7 units by the 27th, giving
an average of A8.3 units for the period.
I'll repeat the figures. Spots - 41; Flux - 90; Ap index - 17; X-ray
flux - A8.3.
Now the ionospheric data for Central France:
The F2 daytime critical frequencies at Poitiers, as reported by Meudon,
averaged 7.9MHz, with the darkness hour lows averaging 3.3MHz. The 24th
was a good day with levels up to 9.4MHz, otherwise there was little
variation from day to day.
I'll repeat the figures. Highs - 7.9MHz; lows - 3.3MHz.
Now the ionospheric data for the north:
The F2 daytime critical frequencies at Ekaterinberg averaged 6.3MHz and
the darkness hour lows 2.4MHz.
I'll repeat the figures: Highs - 6.3MHz; lows - 2.4MHz.
And next the solar forecast:
This week, the active side of the sun will be rotating away. Solar flux
levels are expected to be the 95s. Geomagnetic levels are expected to be
very disturbed with Ap indices up to the 50s. Scottish type aurora could
well occur on the 5th and 6th; levels are expected to remain at
sub-storm all the week. For the south, ionospheric levels are expected
to be affected by the magnetic activity. MUFs during daylight are
expected to be around 18MHz, with darkness hours down to around 7MHz.
Northern stations are expected to be well down on these levels. It will
not be a good week at all.
At present all ground based solar and radio patrol data and synoptic
charts are apparently under review. Unless it can be proved that they
are indispensable for research purposes and funding can be guaranteed;
the USA Air Force, which has maintained these services for many years,
is likely to close them down. It is not known whether the 2,800MHz solar
flux data will be affected as it is supplied by Penticton Canada, but
information concerning all of the other frequencies from microwaves to
VHF are likely to be affected.
And that is the end of this week's solar information.
Finally in the main news, SSL has informed the Society that as of last
Wednesday morning, the latest callsigns issued were in the G0 Uniform
Quebec and G7 Sierra Golf series, and Novice calls in the 2 0 Alpha
Hotel and 2 1 Charlie Uniform series.
