I'll try to fix the FT-847 support in the current HRD beta - I have a FT-847
in the shack for the next few weeks.

Simon,
Before downloading and trying it out can you tell me if the satellite tracking
program works without having the radio(s) connected? One of the original
versions of HRD that I used allowed me to check passes etc without the need to
have the radio in line - the latest version was inoperable unless the radio
was there. I stopped using HRD at this point although the well documented
problem with the non- functioning Doppler compensation control was another
factor.
Thanks,
David

An essential part of this new HRD software is the ability to run a remote
station - mainly EME but also given that the ERP is about 400KW (!) on some
bands we could also melt the odd unsuspecting satellite :-).
This is a technology preview - the aim being to continue to refine this
software over the next years. Almost exactly 3 months' work.
I think I'm right in saying that you can't change the FT-8x7 frequency while
the radio is in TX mode.

Yes, you do *not* need to connect to a radio.
An advantage of splitting this code into its own executable is that I can
maintain it - with too much in the HRD executable it's just too easy to
change something in one area and break something else.
Re: Doppler - you can update Kepler files as often as you want, for example
download latest data every 15 minutes. Listening to CW beacons on 70cms I
hear (and see) no change in pitch at all, so the Doppler's working!

Hi, Phil
If the person asking the question is reluctant to pull the aerial down a
dozen times so that short lengths can be nibbled off each end then a good
method in the absence of any instrument like an impedance meter is to
keep the dipole down in the field and feed it with a coax cable which
electrical lenght is exactly 1/2 wavelenght or any odd or any even numbar
of 1/2 electrical wavelenghts cut for the wanted working frequency of the
dipole.
No matter if the characteristic impedance of the above feed line has or
not the same impedance of the dipole because the impedance Z = R+/-jX
ohm shown by the dipole will be seen without transformations at the
open end of the above coax line so that any adjustement made over the
dipole down the field to get the lowest SWR will have the same effect
as to work over the roof.
Another advantage to use such 1/2 electrical wavelengts of coax cable
down to the shak is the possibility to connect to it a network analyzer
and measure the same complex impedance R+/-jX of the antenna like
to be directly connected with the instrument to the antenna connector
over the tower.
The amount that needs to be cut off or to add cannot be determined
from the difference in the SWR at both ends of the band.
In addition the same value of SWR can be generated if the frequency
feeding the dipole is too low or too hight with respect to the resonant
frequency of the dipole because the SWR meter alone cannot recognize
if the reactive part jX of the impedance producing the same value of
SWR is inductive +jX or capacitive -jX
If decreasing the frequency with respect to the working frequency the
SWR decreases it means that the dipole has inductive reactance at the
working frequency and is too long
If increasing the frequency with respect to the working frequency the
SWR decreases it means that the dipole has capacitive reactance at the
working frequency and is too short.
When the exact lenght of the dipole has been determined and all
reactances are cancelled out probably the SWR cannot be reduced
anymore because the real part R of the impedance is different from
the characteristic impedance of the feed line and at this point a
matching system must be used to get Z = R +/-j0 ohm
If the 1/2 wave dipole is open at the center as the dipole in question
then a T- match with a suitable balun is suggested.
If the 1/2 wave dipole is not cut at the center then a gamma-match
matching system without any balun can be used.

Thanks Simon, I will give it a go.
My comments about Doppler may have been in error, what I meant was the
fact that HRD failed to keep up with the change in the satellites
movement and it was also impossible to use the manual tuning function as
it just reverted back to what HRD wanted it to be at - these points I
brought up maybe two years ago on the help forums!
I like using the satellite function of HRD as, apart from NOVA, I think
it has the best user interface screen of any others I have tried!

Fabiano,
"Ground Control?" It sounds as if you are using the old Satellite part of
HRD. You need to use the new Satellite Tracking program. It is a separate
program, like DM780. You can see it in the HRD menu group which the new
program creates. All the FT-847 functions, including the SAT button, work
fine in the new program.
Alan
WA4SCA
Hello Simon,
Why, the last BETA versions not works with the YAESU FT-847?
In the GROUND CONTROL the button SAT not active the SAT function on radio
and the modes and VFO (SubB, MainA) is impossible to set.
The only the 3.4 v1294 works perfect with my YAESU FT-847 the all others
(newer) not works, doing the same problem.

The version of HRD that I use has a check box to allow manual tuning and it

Works fine on my 847 and 817.

I'm preparing a presentation on the three LEO satellites currently active in
Mode J, and I'd like to include the physical dimensions of each. I need some
help in that regard:
The AMSAT Web page on AO-51 lists it as 150x150x150. The page for AO-27 lists
it as 25x25x25. Can anyone tell me the correct unit(s) of measurement for
each?
SO-50's dimensions are not listed. Does anyone know what they are?
Thanks in advance for any help you can provide.

They are all three 150mm on a side, and share a -very- common heritage. Can

PS FO-29 is also Mode J, but is a transponder instead of a FM repeater.

Drew,
My apologies for a moment of dyslexia. It's AO-51 that's listed as 25x25x25 on
the AMSAT site, here:
http://www.amsat.org/amsat-
new/satellites/satInfo.php?satID=1&retURL=/satellites/status.php
It would be helpful, I think, to add units of measure to the AO-27 and AO-51
pages, and to add the dimensions to the SO-50 page.
Thank you for getting back to me on this.
73,
Tim

Hey everyone,
Is anybody using an Icom IC-T7H HT to work passes of the Mode-J LEO
satellites? Icom's literature reports a receiving mode on this radio "similar"
to the dual-watch function on some of its other HTs (e.g., IC-92AD), which
ought to make it functional as a non-full-duplex option for AO-27, AO-51 and
SO-50. Any help on this will be greatly appreciated.
Thanks!

Errr, I think I spoke too soon. There seems to be some disagreement on the
exact size, but they are all the same size. I'll get a more complete and
possibly correct answer for you.

Hey Drew,
Thank you so much for this. I would really like to know the accurate
dimensions of the satellites and, again, suggest that whatever they are be
posted on each satellite's page on the AMSAT site.
73,
Tim

I was indeed wrong. They are all roughly 25cm/10 inches per side, with some
minor variations. I will attempt to have this correct on the website, and
include the units!
Sorry for my erroneous first response.
