how to post a bulletin to the BBS and have it be rewritten to a list
I was curious if there is a way that I can have a message posted to the BBS and have it rewritten so I can?
send out ?a ?defined list of rms express users individually.
?
I was looking thru the system and havent come across a rewrite window i will continue to look
?
The system is currently a closed system and not out on the public network so I am not too concerned
for outside users flooding my user community
?
Thanks in advance

Re: Mail odd behavior
I always have something strange, or try to do something strange that works differently.? Now my HF forwarding works fine when manually started but only two of the stations follow the intervals.? The other three will only connect when I trigger the forwarding manually.? Go figure...
?
Thanks John.? It may work itself out after a few updates or a new full installer.? It's not causing any grief as there are multiple ways to do it.

Re: Need Advice: RF Only Forwarding
Hello,?
If you are using a station which over sees other? not seeing each other you make it a DAMA master. This master accepts stations and leaves a space for other connecting stations. This is to prevent someone aiming a beam with high power and tight AX25 parameters.?
?
Netrom is a horrible routing protocol and produces a massive data overhead which gives lower throughput.?
?
If you want to send data from one node to the other in a dedicated link use digipeat. And broadcast in the beacon from the DAMA master? digipeater the reachable access nodes.?
?
KPC9612 has DAMA capabilities.?

Re: BPQ Kiss AX25 Bridge Testing
Hi John,

After some additional testing I would say unless you are really curious do not spend any time on this. The bridge itself is switching packets between the two RF ports as quickly as it can which unless I misunderstand the intent of implementing this for AX25 is exactly what a bridge should do. It is up to the "things" on either side of the bridge to synchronize and / or handle timing. So far my tests bridging 10m HF 1200b soundcard s/w TNC's to / from 70cm FM 1200b h/w TNC's have all resulted in some amount of retries even after varying the usual timing parameters (SLOTTIME, PERSIST, FRACK) through a wide range. I may have missed setting these in the best combination for the equipment used but either way the bridging does work well enough if needed as long as there is not a sustained large amount of data to bridge. Thanks for offering to have a look though. 73 de Rich WA3WLH On 3/4/25 19:07, Rich Sahlender via groups.io wrote:

Re: TCPIP over AX.25
After starting linbpq i ran this commands and then it works
?
sudo ip route add 192.168.0.114 dev LinBPQTAB? ? (on sg0yos)
and
sudo ip route add 192.168.5.1 dev LinBPQTAB? ? ? ? ?(on se0yos)
?
Probably wrong way to do it but couldn't run these commands
in the IPGATEWAY configuration.

HF Forwarding partners needed
I'm looking for some HF Forwarding partners for NTS and Emergence traffic as it becomes necessary don't need any bulletins over HF. I have a full time 24/7 BPQ32 station setup and ready to rock and roll here in the lower part of Texas where it seems to be forgotten. If you are interested send your connect script to this station, I will put your callsign in my forwarding file for a connection. To connect to my station, you can find the listed frequencies on WL2K webpage. |
Mail odd behavior
This morning I accessed BPQ Mail from a terminal window on the bpq host machine. Windows 10.? BPQ32 6.0.24.64 and BPQMail 6.0.24.62? (these were distributed together.)
?
Anything that I enter (LM, L, name, homebbs, anything) returns nothing to the terminal.? I can see that it connects to the BBS on the mail app, and the queue value goes to what looks to be accurate.? But nothing on the screen.
?
Accessing WebMail in a browser works normal.
Accessing the BBS from a browser terminal acts normal.
Accessing the BBS from another machin using telnet works normally.
The logs show exactly what the terminal does. No output to the terminal when accessed with a terminal window on the local machine.
?
I looked for all occurrances of my base call sign in my config. I do have a couple and commented them out.? Restarted and the same happens.
Forwarding is happening normally.
Recieving mail is happening normally.
?
Anyone else have this happen to them?? I probably have not accessed the BBS like this for months so have no clue when it started.? So many changes to the config file since I accessed the mail from a termina... Just not sure if this is isolated to my fat finguring the config file somewhere or if others have seen this.? Quite frankly, I don't even know where to start looking.

Re: Need Advice: RF Only Forwarding
Hi Chris,
What you describe is a classic hidden node problem, the mountaintop station hears all, but stations on one side can not hear the other side, so can transmit over one another when talking to or through, the mountaintop.? So setup 2 is best as it has lower traffic levels on both sides on the link frequency.? But in both cases I would set up the mountaintop node in knet mode and let net rom provide visibility to nodes on all sides of the mountain. connect scripts would be trivial, as all nodes would be listed in each systems nodes table, so a simple c node is all that is needed in the scripts.? A digi is also possible but would have lower thruput due to traffic collisions when traffic levels are high because of the hidden node problem above. connect scripts would require using a c node via digi syntax. ? k-net works well for manual node hopping but is not meant for automatic networking.?
That's my $0.02 worth, hope it helps.

Re: Need Advice: RF Only Forwarding
Hi Chuck. Tnx for the reply.
Yes, you are correct - they are hidden from each other, but are on different user frequencies - which means, in Scenario 1, the mountaintop node would have to be a gateway (KPC-9612 or 9612+) and forwarding would have to be during sleep hours.
?
It looks like the dedicated data link will be the better way. That would eliminate "hidden node syndrome" right?
?
Your thoughts...

Hi, Chris: Digipeating is the fastest. Any node-mode would be more polite. In your diagram I guarantee the mountaintop node will be an 'exposed node'. It is likely that the nodes in each of the 2 valleys will be hidden nodes to each other. Is there any chance that there could be 2 nodes on the mountain? Wire connected and each covering a different valley and each on a different channel. 73, Chuck |

Tnx for the info Mark. Will keep you in the loop as the project progresses.

Re: Need Advice: RF Only Forwarding
Tnx for the response, Jeff. If using scenario 2, yes the link would be dedicated, probably on 220. Station B only has a tri-bander: 2 meters, 220 and 440. So, a NVIS experiment won't work. Both stations are a solid S-9 to the mountain.

OK. Will keep you updated. Looks like Mark posted some info too...

Re: Need Advice: RF Only Forwarding

Ok, here are your considerations.
?
Kantronics in KA-Node is creating a NetRom link, if i am not mistaken, and creates a LOT of traffic.? I avoid this at all costs.? But that is just me in my county and my preferences.
The advantage is that a message send from one use to the other as the packets are sent they are ACK'd by the KA-node and that's that.? Then the KA-node transmit to destination and the destination ACK's the packets.
?
If the Kantronics is a digipeater (my preference) then it remains silent except to ID, beacons, and when it receives something to be repeated.
The disadvantage is that the packet is sent by the origin, is repeated by the Kantronics, then is ACK'd by the destination, which has to then be sent back to and repeated by the Kantronics all the way back to the origin for the packet to be considered delivered.
This method results in minimal air time.
?
?
If you are in a sparcely populated area then the first scenario would work.
If you are in an area with even a small number of packet stations then you might get complaints about the amount of traffic heard.

Re: Need Advice: RF Only Forwarding
Hi Chris, My opinion is K-Net since it's good for node-broadcasting and pretty sure for forwarding, And Scenario 2 with backbones for sure. You'd need a second radio at the mountaintop site for the backbone freq. The forwarding script I'm not sure about; K-Net is Netrom-like and does link with BPQ but I don't know the full details on the limitations. In Puerto Rico the network is almost exclusively BPQ, but there are a couple K-Net nodes linked in. Is using HF NVIS a possibility there? If the stations on either side of the mountain are close , then NVIS would make the mountain disappear, eliminating the need for the mountaintop node as the middle-man. The ACDS sections of HF allow high baudrates now, so I imagine a 600-baud, 1200-baud or maybe even 2400-baud standard AX25 AFSK signal would work as a backbone since they are still within the now FCC-legal bandwidth (depending on the quality of the signal). There's also the IL2P variation of AX25 which is supposed to have better performance, which Direwolf and Soundmodem both have, besides the Nino TNC.. Also, for a backbone, ARDOP or VARA would work really well since the two stations would be a dedicated link only between them (ARDOP and VARA only allow one connection at a time). It would be a cool experiment for sure to see how well NVIS worked between the stations especially of they're pretty close. NVIS refracts not only from the F-layers but also the E-layer. For whatever reason, a lot of NVIS documentation doesn't say much about the E-layer, probably because E-layer skip isn't as strong as F-layer, but I have seen it mentioned in a couple docs and I've seen it work. The further the stations are apart, the less strong the NVIS signal from F and E layers will be usually, since the signal has to pass thru more D-layer.
