You use the callsign assigned to you for the particular service in
which you are operating. An amateur license gives you no authority to
operate outside the amateur bands, and should not be used outside the
amateur bands. Use your assigned marine callsign on marine radio.

Nor does it put out 50-100 watts of VHF or HF energy in close proximity to
the ECC. That's a different magnitude and frequency range from that which
the vehicle control electronics are designed to withstand.

In fact there *is* special "equipment" on a police car or ambulance to
protect it from these expected RF emissions. Fleet vehicles marketed to
police and public safety agencies are *factory* prepared for this service.
That preparation takes several forms, most not obvious to the eye. The
important thing to know is that these "police package" vehicles are
designed to be sold into this market, and are tested and engineered to
work with the normal communications equipment used in these vehicles.
More mundane vehicles sold to the public generally *aren't* so engineered
or tested by the factories. If you can buy a "police package" auto,
it'll work fine with your electronics. If the vehicle you buy is not
intended for this service, it may or may not work fine.
Honda has *no* fleet sales program at all, and doesn't market to public
safety agencies. The Toyota Camry, the vehicle that seems most prone to
damage from 50-100 watt VHF transmitters, is not marketed to police
either, and the written warrantee disclaims any liability in case you
fit a high power VHF radio in the vehicle.
>Any car manufacture that tells you radio will void the warrantee is full

Actually, GM *does* warrant their vehicles for two way radio use. They're
the only manufacturer who does that for their full line of vehicles. They
also offer factory assistance, and installation guides. They're definitely
the good guys in this respect. Some of the dealers, independent businessmen,
may not be aware of this unless they do fleet sales, but the zone rep
certainly is, and a call to him will straighten the dealer out.
On the other hand, some other manufacturers only warrantee their fleet
sales models, designed for service where two way radios will be used,
for radio installations. And in some cases, their ordinary passenger
vehicles have neither been tested nor engineered to the same standard.
If you buy one of their models that they also sell to police, a Ford
Crown Victoria for example, then it will be fine. But if you buy something
not sold into that market, say an Escort, it may or may not be fine with a
powerful VHF signal in the cabin.
>As for the guy who was out 1200 dollars because his engine happen to blow

He'd better not laugh too loud. Toyota puts it in writing at the time of
the sale that the vehicle warrantee is void if you put two way radio
equipment in it. You agreed to that when the sales contract was signed,
whether you read the fine print in the warrantee book or not. Ignorance
is no excuse under the law. Toyota ECC systems are *not* RFI proofed
against high power VHF signals, and *can* blow up if one is present
in the cabin with the ECC. And the thing *does* cost $1200 over the
parts counter. (That's robbery, of course, but your only alternative
is the junk yard.)
Nor can your lawyer friend bring a case based on a general merchantability
and fitness implied warrantee because the vehicle is not marketed for
carriage of that type of equipment, and you are explictly *warned* not
to attempt to do so. (Actually, a lawyer can sue for any reason, or no
reason at all, but his chances of winning aren't very good in this particular
case unless he gets a Menendez brothers jury.)
>If the dealer you go to tell you the warantee will be voided, tell him to
>kiss you arse as you leave his business.
Now *that* sentiment I agree with. The only way to get more manufacturers
to do the necessary engineering and testing is to hurt them in their
pocketbooks through lost sales. Be sure to tell them *why* they lost
the sale too. Don't just tell the dealer, tell the zone rep too. It
*may* do no good, amateurs are a small segment of the auto market, smaller
than the public safety fleet market that such manufacturers are *also*
ignoring, but it *may* help.

Well. I do not know.. Last time in here somebody said that
the only way that you can actually communicate via CB band was via
voice. However when I was a little kid I had this small handie talkie
base that operated on the same frequency as CB-14 and guess what else
you could use to talk besides voice? Morse Code! It has a beeping
button that transmitted beeps when you activated the mike!
Oh well. those good ole days of the CB Radio and speaking about 10-200
on the bands (10-200 == the smokey/bear or better known as the police) :).

Good morning. It's Sunday the 7th of August and here is the GB2RS news
broadcast, prepared by the RSGB and intended for all radio amateurs and
short-wave listeners.
First the headlines:-
A radio amateur has helped with a Mayday message,
The Woburn rally takes place today, and
It seems that it really was possible to hear the Jupiter crash on HF.
Hastings amateur, Ron Oswald, G7PIP, helped a yacht in distress to
contact the coastguard. On the 17th of July, he heard a Mayday
transmission from the yacht 'Aida' which had lost its rudder. Dover
coastguard was unable to hear the stricken craft so Ron proved to be
their only lifeline. He was eventually joined by a local coastguard and
a helicopter was launched.
Ron, who is a Raynet member, said it really made his day. The 'Aida' was
observed by the helicopter until it arrived safely at Newhaven.
The RSGB National Mobile Rally takes place today, Sunday the 7th at
Woburn Park, near the famous Abbey in Bedfordshire. Access is easy from
the M1 motorway: if travelling from the north or south, leave the
motorway at Junction 13, not 12, and follow the signs through Husborne
Crawley to Woburn Abbey. Avoid routes signposted to "The Wild Animal
Kingdom" or "Game reserve" and look out for RSGB signs.
The rally features a large trade exhibition, an RSGB Bookstall and
enquiries stand and a members mart area, all under cover. All the normal
Woburn attractions will be available at a small extra charge. The event
opens at 10.00am and refreshments are available nearby. The July edition
of Radio Communication gives full details and a map of the surrounding
area.
The August edition of RadCom carried the full text of the recent licence
changes. It includes a revised list of countries which are members of
CEPT. It is extremely important to distinguish between this
comprehensive CEPT list, and those countries which have signed the CEPT
TR61-01 agreement. TR61-01 permits temporary operation in other
countries without additional paperwork and the signatories are listed in
abbreviated form on the annual Licence Validation Document. The full
list of CEPT countries should be used only to translate these
abbreviations.
As a service to the amateur radio community, the RSGB is making the
August edition of Radio Communication available free to non-members.
Simply call RSGB Headquarters on 0707 659015 for your copy.
According to BBC television's The Sky at Night, amateur observations of
the radio noise from Jupiter have shown a correlation between noise at
20.4MHz and the impact of fragments of comet Shoemaker-Levy-9. Dave
Sumner, G3PVH, presented a paper on his own observations of Jupiter
noise at the AMSAT-UK Colloquium last week. There is much additional
data from amateurs which has yet to be fully analyzed.
An RSGB award for working 15 locator squares on the 10GHz band was
issued in July to Jack Brooker, G3JMB. This was only the second such
award to be issued. The contacts were made whilst operating portable
from Chanctonbury Hill, in West Sussex, locator IO90TV.
Full details of all RSGB VHF, UHF and Microwave awards can be found in
the RSGB Call Book.
The RSGB is looking for someone to carry out the important volunteer
task of Trophies Manager. Applications and enquiries should go to the
Company Secretary, John Hall, G3KVA, whose address is correct in the
RSGB Call Book or can be found on the QSL page in every RadCom.
Now a couple of items of HF DX news from the weekly RSGB DX News Sheet
which is edited by Brendan McCartney, G4DYO.

I have tried the wavelengths that were e-mailed to me and found that
I could hear the various beeps/tones on 10MHz but not on the others.
They may very well come into there own at other times of the day I

leap second at the end of June. The minute from 30 Jun 23:59 to 1 Jul 00:00
took 61 seconds! Quite an event for the world's most accurate ticker.

And from Vanuatu and Fiji, IK0OZD is expected to be operational for the
next two weeks, though the callsigns are not yet known. Preferred
frequencies are: 7065, 14265, 18135 and 21265 kHz.
The Orkneys two-metre repeater, GB3OC, was scheduled to be closed down
this week for a complete overhaul. It is likely to be off for two
months. Further information can be obtained from the repeater keeper
Bill Wright, GM3IBU.
The only rally we know of for today, Sunday the 7th of August is the
RSGB Woburn Rally which was covered earlier in this broadcast.
Next the two events we know of for next Sunday the 14th of August:
The Derby and District Amateur Radio Society Radio Rally is to be held
at Littleover Community School, Littleover, Derby. This is on the A5250,
just north of its junction with the A38. The event has the usual
attractions including a monster junk sale. Details from Martin, G3SEJ on
0332 556875.
The Flight Refuelling Amateur Radio Society Hamfest is to be held at the
Flight Refuelling Sports Ground, Merley, Wimborne, Dorset. Doors open at
10am and the event features trade stands, a bring and buy stall and a
car boot sale. Also on display will be the G4RFR 10GHz EME station.
Talk-in will be on 2m, channel S22, and overnight camping facilities are
available for the Saturday night. Details from Richard, G4VCQ on 0202
691021.
Now a date for your diary:
The next RSGB Regional Meeting takes place at Bristol on Saturday the
22nd of October. These meetings are for members and non-members of the
Society to meet Council Members, Society Officers and staff to discuss
the workings of the Society and amateur radio related matters. For
further details, contact RSGB Zonal Council Member Julian Gannaway,
G3YGF whose address is correct in the RSGB Call Book.
Now for the HF contest news:
The Romania DX Contest is scheduled to finish today, Sunday the 7th at
1600. It is an HF event involving both CW and SSB.
The European DX CW Contest takes place from 0000 on Saturday the 13th,
until 2400 on Sunday the 14th of August on the 3.5 to 28MHz, but not
WARC bands, obeying IARU Region 1 band plans. There are some
restrictions so participants are advised to consult the rules which can
be found on page 18 of the August RadCom.
Next some VHF contest news:
The RSGB 24GHz Summer Cumulative Contest takes place from 0900 to 2100
UTC next Sunday the 14th of August. See April's RadCom page 82 for
further details.
Special event stations active this month include:
GB4GS, which will be aired from the Goodwin Sands, WAB square TR45, next
Friday the 12th of August, by members of the Radio Club of Thanet.
Operation will be on 80 and 40 metres. Times will depend on the tide.
GB4ASH will be at the Ashfield Show, Sutton-in-Ashfield next weekend,
the 13th and 14th. The Mansfield Amateur Radio Society will be on HF and
VHF bands, CW and SSB, plus packet on 2 metres. Visitors will be most
welcome. The operators will be raising funds for the charity 'Kickin 4
Kidz', details of which are on page 5 of the August RadCom.
G2TV, which was issued to the Baird Company in 1926 for television
transmissions, will be activated over next weekend, the 13th and 14th,
by members of the Baird Amateur Radio Society. This commemorates the
50th anniversary of the first multi-gun colour television tube.
Also on the 13th and 14th, GB2YFT will be at the Yeovil Festival of
Transport at Barwick Park Show Ground.
And now the solar factual data
We are currently not receiving the usual telexes of NOAA/USAF data which
is restricting the reports which the RSGB Propagation Studies Committee
is able to publish. We apologise for any inconvenience caused whilst
this problem is sorted out.
A bad sign for HF propagation research was a poll taken at the recent
Space Environment Laboratory Users' conference at Boulder at which 49 of
the 50 who attended were only interested in satellite data services.
Solar activity has remained very low though there have been periods of
Sporadic E on 10 and 6 metres lasting for many hours. No flares have
been reported. The daily sunspot indices have remained very low with the
mean for the period being 11. Solar flux levels have averaged 75 units
but hardly changed day to day. The 90 day flux average for the 22nd of
July was 80 units, this was the last day on which this data was
received. The geomagnetic Ap indices have been around 'just unsettled'
most days, but the 28th was up to 22 units, with the period averaging
13.7 units.
The daily aa indices, as supplied by the British Geological Survey for
the 19th to the 25th July, were mainly quiet with the weekly average
being only 15.4 nanoTeslas, about K2. Many periods were down to only 5
nanoTeslas. We have no X-Ray flux or electron fluence data. The July
average spot count was RI 35, with a maximum of 72 on the 11th and a
minimum of 7 on the 29th. The smoothed count for January 1994 is 36.8
+/- 5. Bartells rotation 2199 started on 3rd August.
I'll repeat the figures. Spots - 11; Flux - 75; Ap index - 13.7; July RI
35.
Now the ionospheric data for Central France
The F2 day-time critical frequencies at Poitiers, as reported by Meudon,
averaged 6.0MHz with little variation from day to day. The darkness hour
lows averaged 3.0MHz, though they varied from 2.9 up to 3.6MHz.
Blanketing E was present most days lasting up to 8 hours on the 31st.
The highs are now around 2000 hours and the darkness hour lows 0400
hours.
I'll repeat the figures. Highs - 6.0MHz; lows - 3.0MHz.
Now the ionospheric data for the north:
The F2 day-time critical frequencies at Ekaterinberg averaged 5.4MHz.
The darkness hour lows averaged 3.4MHz.
I'll repeat the figures: Highs - 5.4MHz; lows - 3.4MHz.
And lastly the solar forecast:
This week, the active side of the sun will be rotating away, solar flux
levels are expected to be about the 80s. Geomagnetic levels are expected
to be quiet up to the 12th, then becoming very unsettled. Ionospheric
MUFs in the south are expected to reach 19MHz during daylight, and the
darkness hour lows are expected to be at about 10MHz. Levels in the
north will be down on these. The coronal holes which have caused a lot
of magnetic activity are now tending to die out.
And that is the end of the 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 Victor
Charlie and G7 Tango Bravo series, and Novice calls in the 2 0 Alpha
India and 2 1 Delta Foxtrot series.
