Talk to AMSAT and propose a geo sat. It’s already in their long term goals.

Even better, join and support the effort.

With dismal HF conditions of late...

VHF/UHF might be the only reliable radio links in the affected area.

The aggregator gets dropped in onto a high point (parachute or helicopter.)

These VHF/UHF feeds now get uplinked to the GEO sat, then downlinked to the ops center, hundreds of miles away.

Go-teems with the necessary ex military skills will be needed for this.

 

These are the operating conditions of THIS proposal.

We really need our own ham band only GEO sat or two.

Then go-teems can uplink and downlink direct.

Re: AndFlmsg comparison; three radios (one with interface) and three android devices; update #2 20190930

Ole Helgerson KI7MBR
 

Had some time this morning to complete testing the UV5X3 with its APRS-K2 cable; e.g receiving messages.

Set up.  Transmit from the Icom T70 connected speaker-to-mike with the Nokia phone; receive with the UV5X3 connected with the APRS-K2 cable to the Samsung tablet.  Units separated by about 12 inches on table top

Results.  The first few tries provided sporadic reception. Then remembered to check the volume setting on the sending Android.  Problem; it was full power.  Tried ~1/3 power, worked a treat, as did ~3/4 full power.

Conclusions.  The APRS-K2 interface cable seems to provide a low cost way of interfacing a Baofeng (or perhaps similar) radio with an Android device.  Costing about $20 ready to go, it is a minimalist approach and a bargain compared to about $40 for the Easy Digi (which has yet to work with the UV5X3) and $100+ for a full on TNC. It will be interesting to see whether the APRS-K2 interface can be adapted to connect with the old Linux laptop running Fldigi or the Windows 10 desktop running Fldigi and Winlink.  That would be way cool.


Re: AndFlmsg comparison; three radios (one with interface) and three android devices 20190929

Ole Helgerson KI7MBR
 

Update.  Had a few minutes tonight and found and "resolved" two issues; VOX and transmission time out.

First, tested VOX vs holding the mic key.  With VOX there either would be a disconnect about every three seconds or a disconnect between the header and the message.  The latter just plain would stop.  Thus tested holdling the mike key down.  That worked, -but- Tx seemed to stop routinely after about 15 seconds.  A clue.

With that thought in mind, checked the new UV5X3 internal settings for mic time.  There is an "end transmitting" setting that was set for 15 seconds.  That was the cause of chopping off transmissions in mid sentence so to speak. Lengthened the time to 60 seconds and ICS 213 forms, which take about 40 seconds, go through letter perfect.

Conclusion.  The BTech APRS-K2 cable works a treat for sending messages when attaching the UV5X3 to either the Nokia phone or the Samsung tablet.  Just means holding the mic key during the tranmission; as with the Icom T70. (Receiving radio, Alinco DR-735).

Now to figure out the EasyDigi's inability to connect with the UV5X3.

Radios: HTs; Icom T70, BTech UV5XR. Base station; Alinco DR-735.

Androids: Moto G 2nd Gen., Nokia 3.1, Samsung 6" tablet

Test conditions. Indoors. HT's set at 1W, Alinco 5W. When testing Baofeng APRS-K2 cable, radios were adjacent to each other in the shack. For testing speaker-to-mic, the shack was isolated from the sending area (kitchen) by a closed door.

Results

Baofeng UV5X3 with the factory APRS-K2 cable.

1.The cable would transmit header, eg. mode and frequency, but no message. Static burst about every 1-2 seconds during message.
2. With the cable, the UV5X3 would not receive messages from the Icom or Alinco
3. When cable plugged in and VOX turned on (level 1 or 2) the mic would still pick up and transmit sound.

UV5X3 "speaker-to-mic" with the Android devices.

1. Months ago, all three Androids would send and receive to each other across the table top. During this test, The older Moto G did not want to receive, but did prove to be a stalwart (mostly) transmitter. Although the program would quit after each transmission, the message would go through.

2. Using the UV5X3 speaker (Androids within 6" either side of radio), the Nokia was able to receive and decipher text messages and a test form accurately received by the UV5X3. The Samsung could pick up the content of the form as text, but the actual form with its message did not appear in the Samsung INBOX.

3. Using the Alinco and it's speaker (Nokia and Samsung perched on the radio), both Androids accurately received the test form in the INBOX.

4.  The UV5X3 had difficulty consistently transmitting text.

Lessons learned

1. It is probably prudent to check Android devices periodically across a table top for sending and receiving AndFlmsg. It is likewise  probably prudent to test Android devices against various radios.  Some devices might be not work well for moth transmitting and receiving.

2. For whatever reason, the UV5X3 does not seem as amenable for hardwired connections as the Icom T70 was with its EasyDigi. Even that set up has its peculiarities re VOX, now starting to send a burst of static between the header and the message which appears to prevent the receiving Android from decoding the message.

3. For my ht radios, the best method of using AndFlmsg now appears to be via phone; speaker-to-mike.

4. It remains to be seen whether the BTech APRS-K2 cable can be made to work satisfactorily. It might be a matter of finding the correct internal radio setting, or it might just be faulty kit. Likewise a quick initial test of an Easy Digi setup ordered for the UV5X3 showed no connectivity at all and would seem to be in the same boat.

#flmsg ARQ Open/Close option not in 4.0.14 #flmsg

Chris - KC9AD <c.doutre@...>
 

Not urgent: I am training some new operators on using Flmsg and MT-63. One thing that some noobs find confusing is the ARQ Send button, as opposed to using the Flmsg Autosend button. In previous versions of Flmsg, I used the ARQ Open/Close option to hide that ARQ Send button. But I have been unable to find the equivalent option in version 4.0.14. Any suggestions? Thanks. 73.

Re: Fldigi & Paspberry PI - Pause on Mode Change

Bill
 

Hi Dave,

 

Thanks – I’ll have to join that group.

 

I did more experimenting today and think I have discovered

what’s causing it.

 

I run with a generic usb sound fob.  When I use the signallink,

I do not have the delay.

 

I found out that if I turn off “Device Supports Full Duplex”, then

the delay disappears.  This corrects it on both of my two

PI’s that are running with the generic USB sound fob.

 

Not sure why having “Full Duplex” on would cause a delay,

but it is totally repeatable.

 

Full Duplex on – Delay

Full Duplex Off – No Delay.

 

I’ll know for sure after next Tuesday night’s digital net.

But I have been testing it for several hours, and with

Duplex Off, everything work fine.

also happens.

Under normal use, most people wouldn't notice this since most qso's are
not doing a lot of mode switching.

I participate on a weekly  Digital Education net which is over a repeater.
During the net, we experiment with a lot of modes, thus the mode change
is occurring a lot during the net.

Is anyone here using the PI and could you please experiment with it
and see if you experience the same pause?

Thanks,
