Anyone know of plans online for one? ====================== Suggest you have a look at an article in QST-October 1990 ,pages 18 - 21 Title : " A compact brick for 6 meters" Author : Pat Bunn , N4LTA Gain : 10 dB Input : 10 Watts A single RF power transistor is used : MRF492 ( NPN) (perhaps a bit dated ,but readily replaceable by a current type. Power supply for the unit : 13.8 V-DC Unit is shown as sitting in a diecast enclosure with a large heatsink. Good Luck Frank GM0CSZ / KN6WH |

Good Luck Frank GM0CSZ / KN6WH it was used in a construction (QST) 20 years ago, and the writer mentioned it was somewhat dated then, not to easy to get gain. the only reason to use it was the price, so I wonder if it is difficult to find a better device now? My first 6m amplifier from '85 used BLY94 because it was free, but it cannot give more than 60-70W 73 jm --- J. M. Noeding, LA8AK, N-4623 Kristiansand http://home.online.no/~la8ak/c.htm |
