Note:

  • To avoid AGC pumping with two transmitters at same location, use different bands.

  • To avoid AGC pumping from local stations within 5 miles, use channels far removed from each other and/or use narrow IF filter when doing weak signal work at high power.

  • If band is busy, use alternate Frequencies above 28.6Mhz.

Note:

  • Stations on 50 Mhz may not be compatible with 144 Mhz.  So plan on using all modes and stay on 50 Mhz band for a given location. Use the dual VFOs. If 144 Mhz traffic, stop tx on 50 Mhz.

  •  All-mode 3 Khz channels use for: SSB voice, SSTV, digi modes up to MT63-2000. Get assigned to a channel to pass traffic and stay there for all above modes.

  • AM channels are for information purposes. Someone may be using them during band openings.

  • FM all-mode channels you may negotiate with voice, and with full-quieting signal, pass text traffic with fast PSK-250  or SSTV image. Use plenty of power/ or are close in.

  • FM Packet/digi channels are for packet or FM PSK text...no voice.
