Ernest; For backbone UHF links, converted Motorola crystal controlled units such as Mitrek units are good as are old Maxxon. When set right, you can get 4-5ms rttl with them. You can also have decent results with Phoenix radios. In some cases with any of the above, you may find a commercial entity looking to scrap these units for more modern models but with a little care these things will run for ions! For VHF, alincos are fairly inexpensive and work fine in the 2-mtr range. 220 I prefer Kenwoods if you can find them. For higher speeds such as 802.11 Microtik with some Atheros cards works decent enough for the cost. Of course, unless you're using a Tek data radio, you'd have the router (wifi) or TNC (uhf/vhf/hf) inbetween the radio and pc. -- If Microsoft intended Windows to be for ham usage, they would have incorporated our protocols into their kernel. 73 de Brian Rogers - N1URO email: <n1uro(a)n1uro.ampr.org> Web: http://www.n1uro.net/ Ampr1: http://n1uro.ampr.org/ Ampr2: http://nos.n1uro.ampr.org Linux Amateur Radio Services axMail-Fax & URONode AmprNet coordinator for: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, Pennsylvania, Rhode Island, and Vermont.
