Hello from Eternal Domain, now 21:1/108!
Got you 5 x 5 here in New Zealand :)
Hello, Chaise... I got you in Portland, Oregon.
Are you a new sysOp or... welcome to fsxNet regardless!!! w00t w00t.
Heh, glad I'm coming in 5 x 5 this way. Been trying to hit NZ on 40m
ham for a while and can't quite get a full exchange on FT8 :)

Hello from Eternal Domain, now 21:1/108!
I just finished a "basic" amateur radio course that was delivered
online. It was taught by retired member of the Canadian Navy.
Amateur radio is way more in depth & involved than I expected, and as
such was was the course... ;)

I've been tempted to, and may yet try, to put the BBS on HF.
So why not a BBS totally decoupled from the internet and phone lines?
I remember thinking it was neat, but at 1200bps you had to have patience.
So a modernized packet radio?
I remember when I ran the original Northern Realms, another SysOp in the areamade his board available over packet radio. He showed me some other systems hewas able to reach over the air, but the baud rate was
something like 1200bps.
Yep, 1200-baud packet. I run a Winlink radio e-mail node over 2-meter packethere. Lots of patience needed, but it's great for emergency communicationsplanning.
I remember 2400 baud modems feeling a bit slow with full ANSI. 1200-baud with ANSI would be a bit painful, and the actual bitrate across packet radiois about half that when you account for ACK packets and
inter-packet waittimes. But the concept is great.
I've been tempted to, and may yet try, to put the BBS on HF. There's a data protocol called VARA HF that can acheive 6000+ bits/sec over 1000's of miles.
So why not a BBS totally decoupled from the internet and phone lines? I'd need to write a small wrapper program to handle the incoming VARA connection
and pass it to the BBS via telnet, but that seems doable.
So a modernized packet radio?
I seem to remember people doing similar in the 80's or early 90's, and I had anuncle experimenting with the same kind of thing with early
internet pages. So let it be written, So let it be done.
I'm sure many of us did, but I started @ 1200bps... went to 2400 real quick butman, I remember the first time I got a 14.4k and could REALLY pull thesoftwarez down. LOL. So funny...
On 11/02/20, Charles Pierson said the following...
So a modernized packet radio?
Basically. Better modulation to fit more data into the same ~3,000 hz-wide audio channel. I want to say it can hit 6,000 or 8,000 bits/sec over HF/shortwave and 28,000 bit/sec across the wider VHF/UHF channels.

I never went to 56.7k until the internet, really.. I lived at 14.4 forever.
i started @ 300bps on a C=64. That truly seems cruel and unusual punishmentnow.
Yes, I did goto a Computer Group BBS back in the day that was @ 300baud... it was all text, and mainly (LOL) a 'bulletin board' of messages for the users in the computer group to chat on...

300 baud was the best. I started at 1200, then got 2400 (so fast!), and jumpedfrom that to a USR Dual Standard. Loved that USR modem. So many red lights! After that 33.6 got popular and I think I got some crappy internal modem.

I've always been interested in the idea since I first heard about it. We used similar methods occasionally when I was in Communications in the
Army long ago. I've just never been in the situation where my available time and financial situations matched.

Before I started the course, I would have had no idea what 5x5 or 40m meant, but I'm happy that I "just knew" what these were when I read
them. Had to look up what FT8 was though, seems to be a digital mode.
Still have to do a lot more studying before I attempt my exam, but I
think I'm getting there. I think... ;)

Awesome! There are so many directions that you can go. FT8 is a super-resilient protocol for HF. Best I've done is 147 miles/watt
(1473 miles on 10 watts). That's with a very simple end-fed antenna strung up on my fence, about 6 feet off the ground. Nothing fancy.
There's another protocol in the same software suite called WSPR. You
can run it on an HF band, and there's other listenting stations around
the world that will listen for and report your signal. Pretty amazing
how far you can get on 1 watt when the band conditions are right. Of course the data rate on WSPR and FT8 is abysmal, but it's just for
making contacts.
Lol, we were similar. 12, to 24, to 14.4.... I stayed @ 14.4 forever

Where you from, bobrob? I was in the Toledo, Ohio 419 area code... and all my friends were BBS folks, in my High School times. It was actually a cool way to grow up with a friend-group that was from all over the 4i9.
Its also simplex isn't it? So you've only got about half of what you'd expect for a normal duplex anyways? My logic might be a little shot
there though...
In dem pre and early internet days, where we were busy all pushing 14.4k+ modems, there were a few people here pushing and sucking shareware stuff over Packet. I too thought it seemed horribly slow, but at the end of
the day it was "free" you could leave it running 24/7 as opposed to a
24/7 phone call which would cost you an absolute motza. But I think it would take a certain mindset to be happy doing it mid to long term.

VHF packet has a pretty low entry cost. You can buy fancy radios like theKenwood D72A that have a built-in packet TNC, but it's not
neccessary. Therig I use to connect into the Winlink mail node is a Wouxun UVD1P, theB-Tech APRS-K1 sound card audio cable, and the
Soundmodem software TNCprogram. It would also work fine using a $30 Baofeng UV-5R radio. So forabout $50 you can be up and running on VHF packet.
Free, and I remember having a ZModem program that let me play Tetris whilethe download was going. What could be better?
I'm not doing any HF antenna work until we're in our new house next
year. Can't see the point in doing any significant work before then.

Starting BBSing in the San Diego area. Moved to Riverside County CA
early 90'sand ran a BBS there from around 90-93. I'd call LD at night into the warezboards run by the rich kids in Orange County and LA. :-)
Oh, I forgot about that! I think that was IceZmodem?
Oh man, I'm going to spend sooooooo much money on this stuff once I pass my exam...

To do overnight downloads on packet, you really needed to be running IP. YAPP (the protocol used for downloading over AX.25) was prone to timing out on busy channels. YAPP was was very much like Xmodem, but with more relaxed timing, to cope with the slower ACKs. I did have success
starting FTP downloads over packet when I went to bed and having my
files ready in the morning. :)
On 11-05-20 18:07, Chaise wrote to Vk3jed <=-
Really? I started looking at running IP-over-packet, just because it
was easy to set up in Linux. The per-packet overhead looked obscene
(40 bytes for IP+TCP headers alone). I think we were defaulting to 128-byte AX.25 frames, so at least 1/3 of the frame was clogged with
headers. Seems like IP fragmentation and increasing the AX.25 frame
size could both help, but those have their own drawbacks.
I'm amazed that good old FTP was so resilient!
Correct, so you have turnaround times to take into accout, nd if it's not a dedicated link, you have hidden station issues, where some stations can't hear others, causing collisions and loss of throughput.
But that said, packet was fun in its day, and I am setting up
another system to play with.

I have to ask, this will be another one of those stupid question. I understand you have full and half wave antennas.. can you have a
multiple wave antenna? Or does making it bigger not actually doing anything?

Tha's inneresting, I thought there was IP on everything... although
there wouldn't have been always. The first stuff I came across was...
ka9q... in relation to radio.. I was looking at something to use under
DOS at the time, I think the wheels fell off that because it was a self contained application not a network driver type thing...

On 11-08-20 19:55, Chaise wrote to Spectre <=-
Definitely not a stupid question.. I'm no antenna design guru, but my understanding is that if the antenna length is not a 1/2 wavelength multiple, the RF energy isn't completely radiated and a portion will return towards the transmitter. That's measured by an SWR ratio higher than 1:1.
It gets a little more complicated, too, because the physical length
and electrical length of the wire are different due, I think, to the
wire resistance. If memory serves, the physical length of the wire has
to be slightly longer due to that.
The ARRL General and Extra books are great resources for digging into
the antenna theory.
Unless you go to a hub and spoke model (single point of failure),
or a series of full duplex point to point links, how would you
assign frequencies?
On 11-11-20 22:41, Spectre wrote to Vk3jed <=-
I s'pose I'm thinking point to point, rather than any other topology. You'd either have to be smart and have it organised in advance with
your partner in crime or send your recieve freq out on your xmit freq. Specifics about what frequencies I have no idea... but imagine that
they'd need to be closeish to each other.
