Re: [amsat-bb] Shoppinglist (Making a T notch filter)
by Robert Bruninga 15 Mar '19

And you can make it without all the connectors at the T if you want. Though it takes some close and inventive soldering of the "T". Since the FM band is 88 to 108 that (I think) is far enough from 145 to add minimum loss. But at UHF, one needs to carefully check to make sure that the FM frequency is not also a multiple of the FM frequency. Tell us the FM broadcast frequency and we can take a quick look.

You need a cable length that is an odd multiple of a quarter wave length long at the FM Tx frequency and an even multiple of a quarter wave at the frequency that you want (2M /70CMs). A single RG213 stub would have about 25dB of rejection and would pass 100 Watts OK. You just need a coax T connector and some matching connectors. To trim the stub, use a set of garden secateurs. If you have a Bao feng or similar radio you could use that on the FM band attached to your T and trim the stub for minimum signal on the unwanted Tx frequency. I haven't run the calculations for how long the stub should be but if it's useful I could do so. 73, Terry Osborne ZL2BAC -----Original Message----- From: Hans BX2ABT Sent: Thursday, March 14, 2019 12:33 AM To: amsat-bb(a)amsat.org Subject: [amsat-bb] Shoppinglist My sis-in-law will be visiting from the States soon and I usually make her bring some stuff for me so I can save on freight costs.

FS-3 pacsat u/l
by kb2mjeff＠att.net 14 Mar '19

Moving off my 30 year old TNC due to poor data performance. The old DSP2232 has done it's job. I'm now in the middle of setting up a software based modem system using my IC-9100, EasyTerm, and HS_SoundModem. The data D/L performance really blows away the hardware based modem. This somewhat surprises me as 20 years ago, we as a group did simultaneous d/l tests using S/W and H/W modems, and at the time the hardware was far superior. The S/W modems and CPU's driving them have come a long way. Anyway what my problem is, how to activate PTT with this setup. I had this working a few years ago, but forgot what I did. Where I'm at now, I'm using vspMgr to try and split the IC-9100's PTT serial port, but no joy. Do I need to split the port? Or use VOX? Any one get this working? Thanks... 73 Jeff kb2m

Re: [amsat-bb] ISS APRS? (Easy switching)
by Roy Dean 14 Mar '19

Funny, when I first got my D710 I looked into doing just that, but could've sworn that all the "important" info was not part of what could be stored in PMs. After looking at the manual again, I note that the list of parameters they show under the PM title say "below parameters CANNOT be stored in a PM". DUH! I must have originally read it as "can" and ignored the whole section due to no parameters of value being listed. So...... much.... wasted.... time!

Yes, it is easy to maintain multiple profiles in the D710. One for Falconsat and one for ISS/NO84, etc Just program one PM memory for normal operation Then one for Falconsat at 9600 using the path of PFS3-1, and then another one for ISS/APRS/NO84 using the path VIA ARISS Then operations of any are only one PM push button away. But you must change the menu item AUTO-PM-STORE to OFF, or otherwise the PM will NOT remember the basic settings but will auto-save-anything you do and so you never know for sure what is in there. I always thoguth it strange that the default for AUTO-PM-SAVE defaults to ON which defeats the whole purpose (in my opinion) of having PM memories in the first plave.

The ISS digipeater has been unreliable in the last couple of years. Firstly, it is turned off whenever there is a special event happening on the space station (space walks, re-supplies, etc). Secondly, the packet module and radio are really old, and we've been seeing erratic behavior from the pair (sometimes it's not on at all, sometimes it's on but weak, sometimes it's deaf, etc.). There is a fancy new ARISS transceiver slated to go up to the station soon, and we all hope that will remedy the situation. Of course, sending a few bucks to ARISS can't hurt that timeline. :) Regarding the switch between the 1200 and 9600 packet sats - there is no easy way. I also use a D710 and it would be nice if you could select a "profile" to swap in all of the path, modem speed, and duplex options - but to my knowledge this is not possible. If you are connected via KISS serial connection, you could automate this - but I'm not sure if there are any software packages out there that would do that - at least without having to manually change all the values via individual KISS commands (which doesn't seem to be any better than using the built-in D710 UI). --Roy K3RLD > Trying to become active on APRS/packet on the satellites using my Kenwood > TM-D710.
