Help wanted "HF packet"
I would like to add a hf port to my uhf / vhf node and bbs.
I have connected yaesu ft840 and a pk232mbx.
Now I'm looking for the right frequencies where bbs <-> bbs forward is or a user channel.
I have read everything about the Mark and space. It is a little confusing.
On this website I have read http://wiki.complete.org/PacketRadioOnHF where they are.
But the STD (standard frequencies) assumes a tone of 1600 and 1800.
Now a pk232 useing 2110 and 2310 as tone.
This is from the website http://www.hamcomputing.org/2011/04/25/hf-packet-primer-for-beginners/
The "mark" frequency for Network 105 is 14.103.4.
The "space" frequency is 14.103.2. So, if you take 14.105 and subtract 1.600 (1600 Hz) from it,
you'll get the mark fryou'll get the mark frequency of 14.103.4. The same holds true if you subtract 1.800 (1800 Hz) from 14.105,
you'll get the space frequency of 14.103.2. This is all fine and good, but what if your TNC doesn't use the 1600/1800 tone pair?
This is where the fun begins.
If you have a tone pair of 1075 and 1275
In LSB mode, we would take the mark frequency, which is 14103.4 and ADD 1.075.
We get a frequency of 14.104.475. Now we take the space frequency of 14.103.2 and ADD 1.275 to that.
We also come up with a frequency of 14.104.475. The frequency, 14.104.475 will be our DIAL frequency in LSB mode.
So the mark frequency is 14.103.4 and the space is 14.103.2 I have tone pair of 2110 and 2310
14.103.4 add 2.110 = 14.105.510
14.103.2 add 2.310 = 14.105.510
So the dail frequencie is 14.105.510
Is this okay, or do I not understand it.
Second guestion.
Is there still activity on the 105net of hf bbs forwarding.
