Re: Topband: Busted 30 Meter RTTY contact
Interesting I do not operate RTTY and do not operate 30 meters. No RTTY equipment. Mistaken identity, or pirate possible. 73 Bruce-K1FZ On Fri, 16 Oct 2015 03:28:59 +0200, Silvo Knuplež wrote: Here is that moment, at 04:25 gmt date 9 october 73 Silvo S51V 2015-10-16 1:44 GMT+02:00 K1FZ-Bruce : > > Anyone lost a 30 meter RTTY contact with E51MQT ? > > I have received credit for one that I did not work. > https://secure.clublog.org/charts/?c=E51MQT > > > 73 > Bruce-K1FZ > www.qsl.net/k1fz/bogantennanotes/index.html (updated). > > > > > > _ > Topband Reflector Archives - http://www.contesting.com/_topband _ Topband Reflector Archives - http://www.contesting.com/_topband _ Topband Reflector Archives - http://www.contesting.com/_topband

Topband: Busted 30 Meter RTTY contact
Anyone lost a 30 meter RTTY contact with E51MQT ? I have received credit for one that I did not work. https://secure.clublog.org/charts/?c=E51MQT 73 Bruce-K1FZ www.qsl.net/k1fz/bogantennanotes/index.html (updated). _ Topband Reflector Archives - http://www.contesting.com/_topband
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 open, at the receiver side, then short it at antenna side at check for a short indication at receiver side, then connect a resistor at the end, 50 100 or any low value and measure at receiver for that value plus 0 to 10 more ohms. If Ok, check for the transformer, Is it binocular ? right core? check for an open of primary winding or the secondary, check for a short between primary and secondary. (the previous test only works if you have primay and secondary isolated). If ok, you would need an instrument like MFJ, Autek, VNA etc to check it at RF level, so use the same resistor (not another) you use for terminating your loops, connect it at secondary and measure the Z o SWR at transformer input. It should be between 50 to 75 ohms 1:1 1:5 SWR. If Ok, transformer and resistor seems to be ok, so I would suggest you temporary disconnect one of the loops from the relays, then connect, the transformer primary to the coax, and one leg of the secondary to the ground pipe. The other secondary leg to one side of the loop. The other end of the loop to one end of the terminating resistor leg. The other end of the terminating resistor to the ground pipe. The antenna should be receiving now. If it works, and you didn't find any problem in the debugging process, then you could have a wiring problem in the box, a relay problem, or both. Good luck, Eddie, LU2DKT --- Spanish version Hola Marco,Si la K9AY es de construccion casera, podemos separarla en varias secciones para facilitar el diagnostico, tales como coaxil, transformador 9:1, reles, cada loop, resistor de terminación y la jabalina a tierra. Primero asegurate que el coaxil que va a la antena esta ok, desconecta el coaxil del receptor y de la antena. Mide del lado del receptor por cable abierto, luego haz un corto del lado de la antena y verifica el corto, del lado del receptor, finalmente colocale de terminacion algun valor que tengas 50 o 100 ohms y verifica este valor midiendo del lado del receptor, es posible que mida de 5 a 10 ohms mas dependiendo del largo del cable. Si todo indica normal, hay que verificar el transformador...es uno binocular? si es asi, con el primario y secundario separados verifica que los bobinados del primario y secundario no estan abiertos y tampoco que esten en corto entre ellos. ( este test solo funciona si NO es un autotransformador) Si esta Ok, necesitas un isntrumento del tipo MFJ, autek, VNA, etc para controlar el transformador a nivel de RF. Asi que utiliza el mismo resistor de terminacion que esta en la caja (no otro, el mismo) y mide con el instrumento que tengas por una impedancia de 50 a 75 ohms o una SWR de 1:1 a 1:5:1. Si esta ok, entonces parece que el transformador y el resistor estan bien, asi que te sugiero que temporariamente desconectes uno de los loops de los reles, luego conectes el primario del transformador al coaxil, una de la patas del secundario a la jabalina, la otra pata del secundario a un lado del loop que desconectastes de la caja, el otro lado del loop lo conectas a una de la patas de la resistencia de terminación y la otra pata de la resistencia a la jabalina cerrando el circuito. La antena debiera estar recibiendo ahora. Si lo esta y tu no encontrastes ningun problema en la mediciones hasta llegar hasta aqui, entonces debes tener un problema de conexionado en la caja, un problema en los reles o un problema en ambos.

Re: Topband: K9AY antenna
I would start by confirming the matching transformer works properly on 1.8MHz. Art ᐧ On Thu, Oct 15, 2015 at 7:51 AM, Marco Quijada wrote: > Hello: > CB1H contest instaled a K9AY antenna.

Re: Topband: Loading tower with SteppIR on top
I have been loading my tower with a MonstIR on top at 83' for about 8 years without any issues. I could not ground the end elements as I have the 60/80M dipole option. I tune the MonstIR to 7.050 when on 160M. I can move the 160M resonance quite a bit by lengthening or shortening the MonstIR. I use an omega match at the bottom of the tower with a vacuum relay to switch caps to cover all of 160M. My gamma is at 40' because I have two rotating side mounted beams at 45' and 50'. The gamma is made up of 3 parallel wires the width of Rohn 45 spaced 2' from the tower. No arcing or sputtering so far. 73, N2TK, Tony -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Tree Sent: Wednesday, October 14, 2015 6:37 PM To: 160 Subject: Topband: Loading tower with SteppIR on top Good day all - thought I would share some more experience I have had with loading a tower with a SteppIR on top of it. As I reported last season - I used a loaded tower at NE7D with a DB-18E on it to work the K1N DX pedition. Recently - I acquired a MonsterIR and after talking to ZL3IX, I decided to connect the two elements at each end of the boom to the boom. This is pretty easy to do - contact me off list if you want more data. I am happy to report this all seems to be working with no issues to the normal operation of the beam. The tower is 77 feet tall and works very well with "only" 20 radials on the ground. I will be increasing it to about 40 soon. I also asked SteppIR if they had ever had any customer complain about problems associated with loading a tower with one of their antennas on top - and they have not. Of course - it might just mean the ZL3IX, NE7D and I are the only ones who have tried. :-) I find that the frequency setting for the Monster affects things on 160 meters as expected. I can move the low SWR point up and down the band some. My nominal setting for 1825 kHz is around 9 MHz. My gamma is about 45 feet high - spaced two feet from the tower. I don't know my exact gamma capacitance - but it equates to about 10 feet of RG8 coax used as a capacitor. See you on the band!! I also put up a Hi-Z 4 square for RXing. Oh - and the PreStew is coming up in about 10 days!!!
