[OZAPRS] 20 m freq

[Ray Wells]

Ian,

I'll make this fairly general.

First, the BBS is reasonably open, meaning there are very few 
restrictions. The one likely to affect new users is that although you 
can create an account, sending mail is initially restricted (I got 
caught out with an unknown new user making mischief some years ago). 
However, if I know you are going to need the service I can create a new 
account and manually massage it to overcome the restriction.

Since HF is affected by noise, and the data rate is only 0k3, 
downloading large bulletins (WIA News, at around 30kb, e.g) might prove 
frustrating, or even impossible, particularly if propagation is 
marginal. Having said that, HF at 0k3 is capable of returning good results.

The use of a mail application that can handle compressed forwarding will 
reduce the amount of data to be shifted, by as much as half. For Windows 
one option is Winpack, and for DOS there's TSTHOST or TPK.

There is also a port on 40m on about 7035.8 (2025/2225 Hz tones). I say 
about because I shifted the crystal as high as it would go a while back 
to give the PSK guys working Europe a clear go. From memory I moved 
about 800Hz higher, but don't rely on my memory.
