I'd like to know the difference in features. What one has that the other does not. General info to help me decide which to buy. BayCom is much cheaper but I don't know much else. Thanks. 73, Daniel ------------------------------ Date: 24 Oct 1994 04:51:43 GMT From: "Mark J.

Here are some of the questions: >1) What kind of radio I should purchase for packet radio? What is HF radio? > What is VHF/UHF radio? What is multimode UHF? Which type should I buy? HF is generally considered to be the bands below 50 MHz. VHF would be the 50, 144 and 220 MHz bands and UHF would be 440 and 902 MHz plus 1.2 GHz. Multimode refers to the operation of the radio, i.e., cw plus SSB plus FM >2) What kind of interface should it buy? I saw some TNC have very low baud rate>about 1200 bp and some have 9600bp. Does the baud rate depends on the radio? Yes it does depend on the radio. Packet operation below 10 meters is typically 300 baud. 10 can have up 10 1200 baud. 9600 bps is permitted above 50 MHZ, although most operation in the VHF bands is at 1200 baud. For 9600 (and faster) the microphone and speaker connections of the radio are NOT use, but you must wire directly to the modulated stage and discriminator. >3) Can I use handheld radio for packet radio? If yes, what kind? Yes, but with a good (external) antenna, not the 'rubber ducky'. If I use>HF or VHF/UHF radio, do it need to have a tall tower (30' to 90' tower anntenna)>? It would certainly help. Not only do you need to hear any station you want to connect to, but they need to hear you as well. Good luck!
