Hi Pete, Any preamp that has loss definitely needs repair. Preamps are simple devices that are easy to troubleshoot, the transistor is a likely culprit

Anyhow, while it shows substantial directivity on broadcast stations, I was surprise by how much the K9AY loop's sensitivity suffers compared to my inverted L. Listening to a broadcast station with the K9AY on 1500 KHz, the station is S6-7 in the right direction and S3 in the reverse. and S9 +10 on the inverted L. There's also something haywire in the K9AY's preamp, which *reduces* signal by a couple of S-Units. Could be I need to replace the transistor? -- 73, Pete N4ZR One of the RBN team _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
