Re: [amsat-bb] AMSAT FD 2014 debrief
I am not familiar with SATPC32, so I cannot answer that. I think I recall discussions in the archives about using a non stantdard split not in SAT mode on the 847, but you can search the archives to confirm. We actually used an icom 821h with a 5 element beam for terrestrial qso's (without elevation) to make our two or three ISS contacts (different users and callsigns). Since those contacts do not qualify for sat contacts we actually ended up failing to get the FD sat contacts since everyone was so wound up with the ISS contacts. Oh well, something to fix for next year ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member? Join now to support the amateur satellite program!

Re: [amsat-bb] AMSAT FD 2014 debrief
The 847 does not allow dual in band operation. If you think about it you would need very respectable filtering more than 100db isolation between the transmitter and receiver to be able to pull this off. In effect you are asking it to be a repeater. It can do this only when transmit and receive frequencies are not on the same band because then it only has to deal with the much smaller 3rd harmonic signal.

[amsat-bb] Re: Ft-847 & icom preamp
I have used mirage and an older preamp with my 847, but not powered by the rf ports. I must admit I did smoke the non mirage through complete absent minded issue. I was trying to play with arecibo on 432 (read excited) and plugged in the digital stuff to the 1/8" radio port while all were powered. When one of the rings shorted, radio went to transmit at full power which killed the preamp. Also be aware 847's have nasty habit of a very short full power burst at powerup on what ever band you happen to be on. Not wanting to trust the rf control part of the mirage preamp, I run direct hard control using the amp control signal port from the radio. ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: Mirage preamps
Look carefully at the power consumption on the preamp. If it is less than the max for the 847 (which I forget the maximum current), you could use it powered from the radio. BUT pay careful attention that anything between the radio and the preamp does not provide a dead short from center conductor to shield. In my case a lightning protection part shows as a dead short. This would of course zap the internal power supply parts in the 847. In my case, I just provide external power and hard key the preamp from the radio. (The preamp is actually in the shack not on the tower.) Another problem in my install is I am using a pair of duplexers to combine the 2m and 70cm to run in a section of 7/8 hardline. The 2m ports pass voltage. The 70cm ports do not and present yet another short circuit on the coax. I do this arrangement to gain the low loss for a 150 foot run to the tower base. I also benefit using this technique to avoid interference problems between 70cm and 2m. This gets me about 120db of isolation between the two ports. There is also another possible issue to consider in that the 847 when first powered up sends a full power transmit for a very short time. Also another stupid pet trick is never plug into the data port when the radio is on. Seems simple, but when the tip/sleeve/ring cross the right contacts, a full power transmit occurs. Yup, cost me my best preamp while playing the Arecibo EME fun a while back.
