I have another piece of the NQ4I Multi station for sale...I saved an Alpha 87A for my own personal use after all of the amps were sold...this amp is clean and relaible. It will come with AlphaMax and it will come with the Alpha DAS (digital antenna selector) combined together they will follow your transceiver from band to band selecting antennas as you go along. Making chasing mults a easy matter. The DAS will include the relay antenna box also. so its a plug and play combination. yours for $2850 pick up in Griffin, Ga. Full legal limit on all bands. The Alpha 87A is also adressable over the internet should you want to remote it.
