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
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 73 Frank W3LPL I just deployed my K9AY loop (ye
Hi Pete, If you are using the blue Array Solutions control box, it is my recollection that when you switch on the preamp, it also adds a BCB filter to the signal path. 73, Joel N9LQ _________________
I was able to find the specs on the Array Solutions control box. Yes there is a bandpass filter when the preamp is switched on . This is copied from the documentation: Preamplifier: 15 dB gain, feedb
Hi Pete - What version of the K9AY components are you using (e.g., original K9AY, Array Solutions, etc) ? Some versions incorporate broadcast band filters or switchable bandpass filters. Could that b
That's a new one for me! A short Beverage for higher-angle signals. Thanks! I need a few of those here for closer stateside signals. :-) 73 Mike W0BTU _________________ Searchable Archives: http://ww
Over my soil the K9AY's were Lazy. I added radials under the elements and they woke up, but directivity suffered a bit. I added 4 more radials between the elements and they woke up even more... And t
Hi Pete, I also had problems with broadcast stations at my 4 EL bidirectional (330°/150°) broadside K9AY arrays 84 meters apart uses three 0° hybrid combiners. The problem was solved by a Hi-Z amplif
Be sure to check your high angle receive antennas near Sunset and Sunrise, especially during this period of high solar activity and wide polar oval. A low receiving dipole (10-15 ft) accounted for up
