So tell us which Fleetsat it is, what the direction of the satellite is, its angle above the horizon and the sort of aerial gain you need. I've checked the theoretical pattern/gain for my 5 ele Triax and the SWR should be below 3 from around 260MHz falling to under 2 at 280 MHz and up as it's roughly 3 x FM band frequency. My south facing aerial would have a main lobe between 10 and 15 deg elevation and a weird pattern with a lobe straight ahead and two stronger lobes +/- 45 deg. I suppose I could feed the input into the DAB input of my low-noise triax preamp and hope it the some gain at 250-280 MHz.

BTW it is not "terrible qrm from the US Navy" it is "causing terrible qrm TO the US Navy". :)

Dave, i hate it when legitimate users of a Frequency interfere with rare accidental dx ;-)
once i was listening to a rare Siberian Taxi at 28.255 on the Russian Taxi band and a bloomin' 10m CW contest qr'ed all over it!

from here the 3 satellites that produce the goodies are at 100, 170 & 190 degrees

no elevation possible or needed for me & Jurgen
I'm using a CLP 5130 Log P
JB is using a Band 3 ant

really glad i've piqued your interest, you have an sdr which is the key thing, narrow your WFM filter to 30khz, no point being any wider as Satcom only rxs that b/w

use 245.2 R Maria (190 degrees) to set up your gear as its the most reliable signal

Nothing at all received unfortunately - maybe something as simple as the DAB section of the pre-amp having a fairly sharp cut-off beyond 230 MHz (they don't publish the bandwidth figures - so it's a guess.

Hello will a fairhaven rd500dx receiver be good for receiving the above transmissions with suitable antenne.

http://www.ebay.fr/itm/Fairhaven-RD500V ... Sw9mFWKeDB

The price is maybe out of reach for most of us but is it a good performance radio ?

^It's a nice unit but that price is ridiculous. I seem to remember they were around £500-600 when new.
Good DX.

Evening Nick and i agree the price very over the top but i wonder if it would be a good unit for the above dx reported by Tim along with possibly out performing the other tuner/ radio's the more experienced dxer's like yourself and other people use ?
I have not switched on my Sony XDR F1HD for now as i need finding time for fitting the antennenland 9.2 outside which perhaps during the holidays soon.

Good bye

the late David Towers used one, but I can't remember him ever commenting on its performance

for Satcom it would be no better than a Uniden BCT15
It has 2 fm filters and neither is suitable for satcom (you need 30 or 50khz wfm)

you'd have to open it up and feed the IF into an SDR with variable bandwidth

but it was designed to be impossible to open, this guy broke 2 tools opening it! http://www.dutchforce.com/~eforum/index ... 1745&st=25


much easier and cheaper to open up the BCT15 or buy a second hand IC-R7000, 7100 or 8500

PCR1000 has a 50khz WFM filter and so do some of the AOR receivers

wideband rx's with a 50khz FM filter "out of the box"
Icom PCR1000
Icom R9500
AOR 5000

forget the AOR alpha, its crap, they rushed it out to compete with the R9500 and with perseus
theres 4 videos of faults!!

Thankyou Tim for your experienced input i have just viewed a youtube video from the link you send from the dutch guy and maybe it is my french but i have difficulty understanding what he is telling us. In the text he looks like criticizing the fairhaven radio but on his youtube video i think he is blown away with the performance. Also the fm sound quality in stereo sounds amazing when maybe connected to a separate amplifier unit ? I think i read on the youtube comment video page that only a couple of 100 these radios were made so i guess when they turn up it is very rare and also why the price is more expensive than for a family of four enjoying a french tout inclus sking holiday.

he is saying the fairhaven performs well but is difficult to modify.
however it doesn't have a 30 or 50khz FM filter for listening to Satcom
listening in 14khz b/w will make the already distorted signals even more distorted and signals are so weak they will be inaudible using a normal wfm filter

also the dutch guy is incorrect to say it has no gaps, it is missing a chunk of low vhf around 36-45mhz


I just heard a timecheck on 269.95 (utc-5) I will check south American time zones

also a new one on 266.95 but very weak and distorted with qrm from Russian telephones

Arethe upper 250.00.0+ MHz channssl difficult receiving with simple equipment or must a dxer intrested have a receiver of your type Icom IC 9500 which i have found on the various websites but will not be purchasing one for it would be cheaper buying a new family size car. I was in shock when i saw the price of those receivers 14000 euros so maybe one will appear on ebay in a few years for 500 - 1000 euros then i can try purchase one lol

Thankyou

you can do it with an SDR
if your location is free of overload you can do it with a very cheap sdr
