If I had not worked in the two-way radio repair industry for thirty 
years, the last thirteen for myself, I probably would not have test 
equipment. My eyes prevent me from doing commercial repairs anymore but 
I kept one service monitor plus the CRO and other assorted small items 
to allow me to repair and align my own amateur equipment.

I have one user on VHF on my packet bbs, and that same user is also the 
only other APRS user in these parts. However, I'm not going to let that 
be a disincentive to me installing an APRS digi to cover part of the 
most significant highway in this country - that's country, not county! 
If the digi does nothing else it will be available for travellers 
passing through. I'm also going to put in a 30m HFgate because there's a 
shortage of those around VK.

My hope is that by providing facilities, rather than joining the crumble 
of AR, it may promote a bit more activity. Amateurs can't use facilities 
if they don't exist. Futile? Maybe, but nothing ventured, nothing gained.
