Preamp suggestions?

Hi (and first post) --

My radio club is getting involved in the "school-contact" program. We're working out what equipment we need to borrow / buy / beg.

. . . Can somebody suggest a reasonably-priced mast-mounted preamp, and the TX/RX relay it will need for protection?

We have some experienced kit builders, if they're needed.

Thanks --

. Charles

Ariss downlink is 145.825, but what is the uplink frequency, is it still 145.825 ?

Micro watts?

I am aware that the ISS is currently using it's standby radio as the Kenwood is faulty but for the past few weeks the signal on 145.825 MHz has been very much down i.e. S4 instead of it's usual 30's +.

Is the Erricson radio transmitting micro watts?

Contacting ISS

When is possible to contact the ISS?? Do they monitor for regular hams?? If so when.

Audio Upload

I uploaded a recording last week of the ISS speaking with a science group in CT. It has yet to hit the Ham Radio Contacts page. Why does it take so long to be posted?

Is BBS Working?

Hi, Jim here, W1JT, just South of Boston MA. I'm a packet veteran but brand new to working the ISS.
I am having a challenge logging into the BBS on board the spacecraft and I'm hoping someone can point out what I'm doing wrong.
I can VERY easily connect to RS0ISS which appears to be more of a keyboard to keyboard type of connection.
When I try to connect to RS0ISS-11 (which I am thinking is the BBS) I just get my 10 retries and then nothing.
Is there an additional step that I'm leaving out?
Is the BBS -11?
Any help is really appreciated!

animation how the ISS Space Station is builded
trough the years till how it is now.
Really worth to visit:

The ISS Kenwood TM-D700 & TM-D710 radios are in the Zvezda Service Module.

The ISS Ericsson radio is installed in the European Colombus module:
