Don, You bring up some good points. I got a couple of hundred feet of Flooded Commscope 75 ohm "RG-11" type at a good proce. I don't have the part number handy. I've been very happy with it at 100 wa
Frank, That is true but a 1/2 wavelenght at 160 meters is quite long, about 260 feet; shorter with the velocity factor. Mike N2MS -- Original Message -- From: donovanf@starpower.net To: topband@conte
All, I'll try out the CATV RG-11 before spending my money on 50 ohm coax. It will also save me the touble of digging another trench. Mike N2MS Ive been using that CATV RG-11 since the late 70's as ju
I have both rigs. I use the K3 for CW and the TS-590S for SSB. For casual operating I like the TS-590 better than the K3 and it is also half the price of the K3. I have one issue with Elecraft servic
Gary, Contact the Kenwood Service Center and give them your email address. They will then send you an email when they are ready to upgrade your rig. The secondary receiver in the TS-990 is essentiall
Matt, I started using surplus stranded high temperature teflon coated wire for my radial system because I got it at a good price. It is flexible and easy to work with but I noticed that if the ends w

Jim, The Mobility industry has been using pre-distortion. It has finally been implemented in the Hermes and Apache Labs Transceivers by Warren C. Pratt. He has won the ARRL Technical Innovation award
Bill, Mouser has the Fairrite core 2631803802 for 6.94 single lot quantities. Mike N2MS FT-240-61 cores. Amidon was $9/ea, Mouser (for the Fair Rite equivalent) was $14/ea. I was only ordering six co
I'd use their dog wire because it has PE insulation. iwc2carl on ebay is my favorite supplier of bulk wire. He's very reliable, consistently less expensive (including shipping) than the retail stores
Could it be coming for Cutler ME, the site of the Navy's VLF station? Maybe they are running tests on a some MF system. Still hear it 8AM local time in mid-coast Maine. Running S5, S6 / slight QSB. C

The Topband reflector has a worldwide audience so it makes sense that Vlad mentions it here. Other regions of the world will have good propagation at that time. Mike N2MS Then pray tell why is Vlad a

I'll have to agree with Eddy. When I started on 160 meters in the early 1970's I had to build a receive converter and used a Johnson Viking 2 for the transmitter. I recall the only radios that suppor
I use these ground bars. I don't like soldered connections outdoors. I picked up my ground bars at a hamfest. They are made out of copper, not aluminum. Does anyone know where I can purchase the copp
If you did locate the offender what would you do? You could report him (or her) to the FCC but the FCC would probably not act until they could catch the offender in the act. These DQRM offenders act
I don't think you would have noise from the line except if there is a fault that is causing arcing at an insulator. I'd hate to live near the end points where the AC to D and Dc to Ac conversions are
The actors on 14.313 were on the air for months. They also advertised their calls so it was probably easy to track then. It's different if a DQRM'er is on sporadically and on different frequencies. I
