I have mine for 10+ years now, bought it used. It’s a solid radio. UHF/VHF and HF in a (for the time) small package and everything works well. I use mine mostly for satellite work and its designed to do this well. CAT control can be a bit touchy and most software which talks to it is pretty outdated by now. My biggest issue with it was the relatively ugly looking blueish-white LCD display. Its harsh on the eyes IMHO. I acquired a color filter foil which gives it now an amber color, much nicer looking.

If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2023-05-26 23:30 UTC.

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

Hello Robin, I have used my FT-847 for terrestrial VHF/UHF and satellite work, but not in more than a year or so now. I have not used it on HF. It also survived a lightning strike on the power line that seems to have hosed the speaker output (but not the headphones) -- I'll fix this someday. In general, I'm pleased with it. It is not an IF DSP rig like my IC-746Pro, nor is it a full SDR, but with the the 400 Hz CW crystal filter from INRAD (http://www.inrad.net/product.php?productid=158&cat=18), it works like a champ. It also has audio-stage DSP, which, when enabled, works wonderfully to clean up the post-IF crystal filter output. You'll likely want to put in a crystal reference heater. I have some bookmarks, but I'm not sure which one I used. Here's one that looks familiar: http://www.frenning.dk/OZ1PIF_HOMEPAGE/QH40A.htm Something I dislike: The RS-232 CAT control messages have no checksum (unlike Icom's CI-V), so any stray RF may/will cause the radio to interpret CAT messages from the PC incorrectly. This means it might change modes, bands, etc. during a QSO on the bird with Doppler tracking enabled. I've heard that the fix to this is to change out the RS-232 connector on the back with a USB dongle that uses a FTDI USB<->Serial chip. This means that all the serial CAT traffic is protected by the USB's CRC protection on the cable and the actual UART signals only travel on the PCB within the rig. Plugging a USB<->Serial adapter right into the back of the rig, skipping the intervening cable, might also solve the issue, but that depends on how well the USB serial adapter's electronics are shielded. This FAQ will come in handy, in general: https://www.supercontrol.de/cat/ft847faq/ft847faq.htm 73, --- Zach N0ZGO

I bought one of the first ones new....A solid radio. Only problem ever is the pots become noisy over time and I clean them with DeOxit....Not todays SDR type radio but a very good VHF/UHF radio....I have not used mine of HF but twine or twice...Diff RF outs a plus...I built a keying box for amps because keying for each band is brought out on a diff pin on the rear. Neat idea...The mod of replacing all band switching diodes with Schottky diodes is a plus...

TEVEL-3, 6 FM transponder activation
by david.greenberg＠bezeqint.net 26 May '23

26 May '23

Hello All, TEVEL-3, 6 FM transponders have been activated, starting from 26.05.23 18:35U for 72 hours. Downlink frequency = 436.400 MHz Uplink frequency = 145.970MHz NO PL tone. All Tevel sats transmit a telemetry beacon every 20 seconds. When the FM transponder is on beacons are off. The transponders are selected while we try to have minimal footprint overlapping ( TEVEL-1 and 8 are not functional). 73, David 4X1DG
