Subject: 6m Packet Questions?
To: ham-digital@ucsd.edu
>1. Can a Technician class license use 6m?
Sure, look in your license manual, you can use all of 6 meters, except for the
segment from 50.0-50.1. That's CW only (you can still use it, but only for CW!!)
>2. How many stations/nodes etc can be found on 6m?
Not many, this may vary from area to area, but in the east coast, I don't know
of very many individual stations on 6m packet, if any, it's being used as a
high speed backbone, (BBS to BBS links only), so I don't know of any individual
stations on 6m packet. (this is in the northern Delaware area)
>3. What kind of "range" can be expected at 6m?
Depends on band conditions, antennas, power, etc. Figure about a 50 or so mile
radius again, depending on the power, antennas, etc. Under special sporatic E
or F layer propagation, you can talk across the country on 6, but during normal
conditions, figure about 50 or so miles, some more, some less, depends on the
individual station.
>4. Is Packet at 6m any different than at 2m?
Well, as I said, around here, 6 was only used for backbones. I could be wrong
(it wouldn't be the first time!!), but most people shy away from 6 due to
TVI/RFI concerns. Especially if you're going to use FM, I'd be careful to have
a really clean and well filtered setup, especially if you're going to run more
than just a few watts. My suggestion would to go up on either 222 or 440 and
see if there's anyone up there first before trying 6, or maybe even go to 10.
The 10 meter monoband/25 watt rigs are cheap now, and the band is begging for
use, so if you put up a node there, especially in the 28.1-28.2 segment, both
novices, and technicians (with code) can use it. You'd probrably find a few
more users up on 10 than 6.
Good Luck,

Subject: Looking for CFG for BPQ/FBB system
To: ham-digital@ucsd.edu
I'm in the process of setting up a Packet BBS.
The system is to run BPQ with two VHF ports (UHF or 6m may be in the future).
The BBS software if FBB5.15C. JNOS is a possibility....probably after my
copy of Desqview arrives.....probably in a week or two. I also have a
Telebit T2500SA on the BBS.
Can some Sysops who are also running FBB/BPQ systems please Email me their
configuration files?
Please email to "dreamer@lhaven.uumh.ab.ca", my feed to this group is currently
down...so I probably won't see any followups.

If your HT keys when there's a current drain in it's microphone port,
you can check out the current need to activate transmission by connecting
the leads through a variable resistor. Adjust a 10K potentiometer until
it just keys the unit. For a reference point, I've found that the Yaesu
FT-416 keys with just under 3.0K in line or a current greater than about
1.7 mA at 5V (Normally the unit "expects" to see a microphone with 2K
impedance, or a 2.5 mA drain, for TX keying).
