Hello to all beginner HF packet ops,
I thought I would write a note with a few suggestions for general HF
packet operation.
There have been a few problems on some of the HF packet frequencies lately
because of some stations being apparently unaware of some of the basics
of HF packet operation. Some of these basics are obvious, some are things
we don't think about unless they come up from problems we might have
in HF operation.
One point that is very basic but is sometimes overlooked, is that the
frequency spacing on HF packet on 10,15,20 meters esecially, should be
2 KHz, i.e., 28.103, 28.105, etc. If one operates on 28.102, it will interfere
with 28.103. This may sound simple but take a listen on 10 meters on a
Saturday!
PACLEN on HF should be short for 300 BAUD work, 24 to 40. MAXFRAME of
1 works well. FRACK of about 4 - 6 is usually OK. DWAIT of 200 - 400 msec
is a polite range. Remember, the chances of getting a short packet through
on a crowded HF freq are much better!
In general, although there are certainly a lot of very interesting HF
BBS' around, such as 3B8FP on 10 meters, it is probably a good idea
NOT to browse around HF BBS' the way you would on your local VHF system.
Log in and enter your information (N,NQ,NZ,NH etc) but avoid downloading
bulletins unless u know what u are looking for, because most HF BBS', at
least stateside, have similar stuff on 'em. (there are always exceptions).
I always log into new HF BBS' that I see so the BBS will have my info
for its users. I NEVER do a plain "L" or "LB" command, because chances are
that I would be asking the BBS to list upwards of a hundred messages, which
would cause a timeout for sure!
Certain frequencies on HF are considered by some to be "reserved" for BBS use.
14.107, 14.109, 14,111, 14.098, 10.147, 10.149, 28.109, 28.113 are among them.
This is not a RULE! It does not mean we are supposed to stay off these freqs
but we probably should avoid having regular QSOs there as it can interfere
with forwarding (of the stuff that ends up on our local VHF BBS'!).
Use your judgement and things will go smoothly. Good frequencies for QSOs
are: 14.105 ( lot of gateways),14.103, 14.101, 28.099, 28.101, 28.103,
28.105 (lot of open BBS, DX stations), 21.103, 21.101, etc.
You can find 1200 BAUD packet on 28.180, 28.185, 28.190, 28.200 (notice
5 KHz spacing). Set your TNC as though u were going to work VHF (VHF ON,
HBAUD 1200, for PK232, e.g.). Tuning is tricky without a special tuning unit
but with a little practice it is not too bad.
Many nodes and interesting gateways are found on 14.105, 28.105, 21.101 and
you can work some interesting DX on these bands. I have worked 6W, 3B8,
CE0, HC8, A45, 5B4, ZS3, TU2, TF3, FM5, 9Y4, VK3, and many others, just in
the few times I have QRXed my BBS to use my TNC for more fun stuff!
I hope this basic infomation is of use to anyone who is new to HF packet.
Enjoy the bands!
73, Chuck SYSOP @ WA1IIE.ME.USA.NA 145.03, 10.147, 28.109
