Re: PCSAT-1 over Europe
by Håkan Harrysson 09 Nov '07

Hello! It looks to me it is more different stations passing thru, It could also be that the word is out there is a good APRS satellite working FB at the moment. I did see a truck from TF and also some more interesting stations yesterday. 73 Hakan SM7WSJ Yes, when we changed the path to WIDEn-N, it took a while for people to see the bulletins. But the switch to the universal APRS path of WIDEn-N (Usually WIDE2-2) is being successful at slightly reducing the number of duplicate packets. I wonder if those in Europe have seen an impact?

Re: Ampire 146-OS pre-amp schematic?
by Ronald Long 09 Nov '07

The FET is 3SK121. The five transistors used in the control circuitry are all 2N2222. I can send you the schematic and all the other info that came with the preamp, purchased 18 years ago! ron w8gus

I received the answer off-list but will post it here for the archives: "The GaAs FET is a 3SK121 all the other transistors are 2N222". Looks like a 3SK121V is available from rfparts.com. Now to find the data sheets & make sure it will substitute. --Mike WQ5C At 05:44 AM 11/9/2007, Michael Pfeuffer wrote: >Hi all, > >Does anyone happen to have a schematic for an Ampire 146-OS pre-amp?

PCSAT-1
by Chris Bloy 09 Nov '07

09 Nov '07

Hi All, I just wonder how successful digi'ing via PCSAT using a TH-D7 has been? I have real trouble with 5watts and have yet to hit it successfully, 50watts yes, but i am sure thats not good. I believe that its down purely to usage here in Europe as she appears to get hit multiple time by the same stations? Same as AO51 for example, its taken me a few passes to understand that multiple stations transmit at once and cause a strange clash, almost like you need to change freq.. but the signal strength is there!! Maybe this stops the 5watt stations from actually being relayed?? Just a though and would be interested in your comments, does this happen so much in the US?? Thanks, Chris Bloy
