Topband: Sanity Check on K9AY Loop Sensitivity

[Frank W3LPL]

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

Subject: Topband: Sanity Check on K9AY Loop Sensitivity

I just deployed my K9AY loop (yes, I know I'm late).  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?
