Topband: 160 mts try with LU2DKT

Hello topbanders, trying to be ready for CQWWSSB next weekend, I am planning to go to the station a few days before the contest to get the station in order, specially the new antennas. So, in spite of conditions from here are horrible on low bands lately, anyone

Re: Topband: Current Distribution on Buried Radials Used With Vertical Monopoles

Hello Richard, and all Topbanders, I am not going to discuss the accuracy of what Brown, Epstein and Lewis found, only I am just curious about one thing.. Everytime I measured my radials with a current probe (home made), the total current entering the vertical is not equal to the sum of each

Re: Topband: Current Distribution on Buried Radials Used With Vertical Monopoles

A specific description from you about the ground used for radials would be very interesting. 73, Guy K2AV Guy and all,   Unfortunately the only data about terrain is almost flat farm land conformed by humus and neutral PH. Before having the tower and just for fun, I decided to

Topband: Off-topic - LU2DKT - Visit to Praha, Czech Republic

Dear Topanders, I will be visiting the city of Praha during June Friday 12, Sat 13 and Sun 14th. If any local or visitors is around and would like to share a beer (or two) during the afternoon/night, it will be my pleasure. According to QRZ Jiri Ok1RF (CS2C) who I already contacted on TOP, live

Re: Topband: K9AY antenna

Hello Marco, If it is a home made system, we can separate it in various sections for debugging the problem, coax, transformer, relays, loops, terminating resistor and ground. First be sure, your coax is ok, disconnect from antenna feed point, check with ohms meter for an

Re: Topband: Zone 2 on 160m

Hi Steve, If you still need zone 13, I plan to be active during the week previous to CQWWSSB and also during the contest only on 160. Also I plan to participate during CQWW CW and a few days prior to that in slow motion (10WPM) If you still need it, drop me a note. BTW I also need zone 2. So

Topband: VP8STI and Propagation to LU2DKT Argentina

I am rather confuse about how is working propagation to Argentina from VP8STI considering we are not far away and propagation to VP8ALJ from us just follows a more standard behavior.  From the first night, 40 mts propagation to them was as it has to be. On 80 mts it is a little strange because

Topband: AIM4170 in TDR mode - LU2DKT

Dear Topbanders,                             I would like to share with you an experience using AIM4170 to measure our beverages. Prior to the last CQWW and to install our 6th beverage, instead of using the Autek or the MFJ to test the installed ones, I decided to play with the AIM4170 in TDR

Even though I answered to all request for the images via direct mails, thanks to Steve N2IC and Sam N5FO both images are now uploaded for better sharing. As a reminder of my previous update, the scans were done from the beginning of the coax and they show the coax, the transformer and the

Topband: Inv Vee mod question

Dear Topbanders, I am planning to place and Inv Vee for 160 on the top of the building where I have no much space so the arms end will be a little closer, no more than 24 mts apart. My question for those who can model it is: Could I get a better low angle or improve it performance to long

Re: Topband: WD1-A as radials

We has been using WD1-A since a few years, we split it in two and seal the remote end to minimize moisture or water entrance. When the ground is under water (flooded) for some days, even being the plastic strong, it deteriorates faster. If the terrain doesn't flood, it last some years Regards

Re: Topband: KV4FZ from the eyes of the USVI

Many thanks Edd for sharing the linkI will miss Herb on the future 160m contests. He was a very good company specially when conditions were pretty closed he still had a good signal into Argentina. RIP Herb. Eddie. LU2DKT Sent from Yahoo Mail for iPhone On Monday, May 4, 2020, 1:08 PM,
