International Space Station (ISS) amateur radio downlink

The International Space Station, received in West Sussex (South coast of England).
The downlink is centred on 145.800MHz using narrowband FM - although remember the Doppler effect!

I believe the ISS travels at around 17,000 miles per hour and flies over top of here between 5 - 8 times per day, audible (and visible sometimes at night) for 5 - 10 minutes at a time.

The receiver is a brand new Grecom PSR-295, connected to a random-length 10m long wire antenna .

Hello sonnysingh03

I'm afraid that I'm going to have to correct you here. The (legal) CB band is centred around 27MHz in the UK. As you can see on the scanner, I was receiving the VHF frequency of 145.800MHz, which is towards the top end of the 2 metre amateur radio band in the UK.

Have a look at the bandplan on the RSGB website for further details of downlinks from space on this frequency.

A long wire antenna will receive the ISS very well, when it's above the horizon.

thats vhf/uhf ham you are talking about.

ham radio is known even more for the hf bands, between 3 and 30MHz, 80m 40m 20m 15m 10m plus 60m 30m 17m 12m

hf=shortwave (they can bounce/propagate around the entire earth)

[quarknimble]

so you wire antenna is 5 wavelengths long...is that a magic formula for 2m band?

@sonnysingh03 - Ahh. Yeah. What you're hearing is not CB, but ham radio operators :) Licensed amateur radio op's use the bands between 144 and 146mhz, and 430 to 440 mhz. lol "dodgy things" haha :D

@carterproductions your probly right, but some times at night i tune in to 145.000-160.000 and i pick up a hand full of CB's you know old people talking about dodgy things lol.

@sonnysingh03 145.800 is definately NOT the CB/HF band.. they're wayyy down the other end of the radio spectrum.. CB runs around 26 - 27mhz, and HF technically finishes at 30Mhz (starting at 3) - 145.800Mhz is right in the 2M ham band.. Google: ARISS

@sonnysingh03 yeri is talking and ansering kids from a school the ISS seems to do that alot on thair radio contacts

[vanderleySCL]

Very good!!!

[sonnysingh03]

conversation sounds too cheesy to lol

[sonnysingh03]

I have this scanner and this is not the space station, this is the CB/HF band.
