I have had good luck fixing these noisy computer power supplies by putting a high quality AC line filter in the computer AC line cord. The W3NQN AC line filter and the ICE AC line filter work great.
Hello Ron: You might want to take a look a my QST article about the Lazy "V" array that I used and was published in the early 90's. I installed the K8UR array and the full sloper K1THQ array prior to
Hello George: Several folks have asked for additional information. Here it is. My co-authored article on the 160 meter inverted parasitic slopers (4 wire elements) was published in QST, page 36, Augu
Several years ago a few European 160 meter stations posted lists of frequencies in Europe to this reflector that had carriers or other interference on them from 1.8 to 1.850 MHz. Can someone from EU
Earlier this week I asked about topband frequencies in Europe that have carriers or other interference on them anywhere from 1.800 MHz to 1.850 MHz. I have had 3 replies so far: 1818 and 1836 are bad

That being said, how hard would it be to find the Orion AGC parameters that would cause the exact same AGC characteristics as the R4C? 73, Tim K3LR _______________________________________________ Top

JT! Hands down, the Icom IC-765. Check out the Sherwood specs page and the ARRL review. Outstanding receiver and fully computer controllable. 73! Tim K3LR ____________________________________________
Jim, You are correct. The 10 to 11 dB loss I have is measured on 80 meters. It is half of that on 160. I stand corrected. 73, Tim K3LR _______________________________________________ Topband mailing
The excellent antenna forum presentation by ON4UN, W1MK and ON6WU given at Dallas HamCom and at Dayton 2005 has been loaded on the web thanks to John, ON4UN and George, K5TR. Go to http://www.k3lr.co
Hello Bob: I suggest you contact Jim, K4SQR at Comtek systems. He has DPDT heavy duty relays that I use and they work very well. http://www.comteksystems.com also k4sqr@juno.com 73! Tim K3LR http://w
I am hearing carriers at 4 KHz increments on 160 meters. They are not BC carriers. They start at 1804, 08, 12, 16, etc. I think they are generated by a neighbors computer power supply, or something e
Maybe the 1026 has not helped null your noise problems, but there is another very useful mode of this fine unit! I learned this technique from my good friend Tom, W8JI. Bring up the gain controls of
I purchased a 160 meter single band mobile whip antenna at HamCom in Dallas last summer. It has a standard 3/8x24 thread on the bottom, a lower mast, a long black coil in the middle (about 1" OD and
Hello Adrian! I have installed more than 30 miles of radials for my 160 and 80 meter vertical arrays. All on top of the ground. I pin the ends with galvanized landscape hooks. Within 3 months they bu
Hello Mark! This 160 meter vertical Yagi array is well documented in the ON4UN Low Band book (last two editions). I think 6 parasitics may not be justified. The half power beam width is large enough
