> Hi all,

> I am very sorry to inform you that after requesting formal permission to
use VHF/UHF HAM satellite band from Gibraltar (by using the avaliable
Gibraltar Regulatory Autorithy form they have send me by email to fill),
they have denied me the permission to broadcast from its territory. They
have told me that Spain licenses are not recognized by the colony. This may
not affect other nationalities, so if you have a license from another
country You can try if you visit the colony.

entity Ceuta & Melilla) and all seems to be fine for this. I still can not
specify the exact date but It will be in mid-August (probably between days
12-21). It is very possible that I will only be able to be in the city one
or two days, but because this visit if flexible to me I will try to do it
one day with a good pass of SO-50 and Fox 1A (and maybe Lilacsat if it is
active).

> Hello all,

> I have a question for those of you much more experienced than I. It relates

>
> I have two cross polarity yagis, one for 145 and the other for 435. Each
> of these antennas has two separate feeds for the H and V polarities. The
> two meter antenna has two feeds, both at about 14 inches from the end of the
> antenna boom. Jumpers from the connectors will be secured to the very end
> of the boom and trail off to main feed line connectors below the AZ rotor.
> The mount point of this boom is 5' 2" from the end of the boom with the
> driven element. The 70CM yagi is an end mount but the two connection points
> are offset from each other. One is 17 inches from the back end of the boom
> and the other is 24. Coax jumpers will again be attached to the boom and
> will trail off to connections below my AZ rotor.
>
> I will be using two separate rotors, (A G5400 or G5500 is not in the
> paycheck right now), an elevation rotor with a 4'2" boom to mount the two
> antennas and an azimuth rotor which will have a probably 2' maximum mast

> I had an AMSAT table at the Scottsdale Amateur Radio Club's "Springfest"

> UTC), had nice crowds.

> for demonstrations - AO-73, XW-2A, XW-2C, and XW-2F. The three XW-2

Germany to go inline with the hand mic of an FT-817 or similar style Yaesu
radios. http://www.box73.com/product/4? I know that compressors are
generally not used when operating on satellite transponders, but I was
wondering if given only 5 watts output (or less) it might not be useful. If
anyone has any experience using one on these on the linear birds, I would
like to hear about your experience. Did you use a stock Yaesu hand mic with
it, headset or what? How did it perform, etc.? Replies on or off list welcome.

> Thank you to those that sent me tips on who the 'other Nevada rover' might
be. I have in fact found out who it is and we have had a very lengthy and
productive chat. He lives in Nevada, has a motor home and has plans to take
a weekend to go operate from a rare grid not terribly far from his home. He
is not a new sat op, but 'grid roving' is a new aspect he is in the process
figuring out. He has asked for my help on working out a few details as to
gear, logging, etc. I am only too happy to assist. I will let him announce
his own plans, as that is only polite, but I will say that if everything
goes as planned, our schedules will not conflict. He should be operating the
weekend BEFORE I arrive in Nevada, with him wrapping up the same day I cross
the state line. =^)

listen to a net and caught the callsign of the station conducting the net
who was in Houston. It was not necessarily his station and/or node that was
the problem, the signal could have been coming from any number of nodes
across the US that might have been connected.

sent through the IRLP website. He is apparently not getting any e-mails from
me directly despite being the same e-mail address. I'm trying to confirm
what reflector & channel(?) he was connected to and then see if there is any
way to research with IRLP to find out what other nodes may have been
connected at the time. You know, detective work.

anyone there been receptive in the past regarding resolution of interference
with the sats? It's all very frustrating as I don't see any central point of
contact on their website and not getting any more communication from the one
guy I heard in Houston doesn't help either. I made every effort to be polite
and respectful in my communications (honey versus vinegar), but with some
people that just equates to a license to 'blow you off'. =^)

The IARU Region 1 Treasurer Eva Thiemann HB9FPM visited Gibraltar last
August. She noted that:
"Gibraltar is not part of CEPT and the authorities do not issue reciprocal
licences for HF operation. But for some time it is possible to get a licence
for operating on 6 and 2 m." - apparently not 70 cm.
The Gibraltar Amateur Radio Society has some visitor information on their
website at
http://www.gibradio.net/visiting.htm
There are still many countries in the world where reciprocal operating is
either not permitted or is difficult to obtain.

Remember that AO-10, AO-13, and AO-40 at apogee were all at about
geosynchronous altitude or higher, so hams have experience operating
full duplex with such a delay.
