Which reminds me of an old incident ... A friend of mine asks... I have this problem with my car... it stalls every time I go up hill... Do you know what I have to do? At which he got this replay: Tr
Given the large investment necessary to bring up these large towers, I all ways wondered why they do not incorporate de-icing facilities into them.!? What is an other $100K when you already spend mil
This is why hams are not allowed to build suspended bridges :):):):) Hope somebody learns from this mishap :( Alex, N2NNU List Sponsored by AN Wireless: AN Wireless handles Rohn tower systems, Trylon
No need to get defensive Mr. Tower Tech :) It is obvious that the death of the four crew members and the loss of several million dollars caused by the collapse of the tower was due to the phenomenon
The key word here is "delivered" :) What do the engineers "deliver" ? A piece of paper called a blue print? NO! The engineers have not delivered. They just put a "feasible" dream on paper. The rigger
Pete, In general, today's transceivers will reduce the output power function of the detected level of the SWR. Thus, the more SWR you have, the less drive from the transceiver is available. As all ot
Tom. You are promulgating wrong ideas and concepts which will repeated by the neophyte. Please go back to the books and redo your homework about energy conversion/conservation in RF systems. Besides,
OK... here is _minimal_ tech answer... no formulas, no confusion. SWR is a wave. It does really not exist per say. It is just an envelope modulation on the carrier related to group delay, medium velo
This is really the last one :) I am going to give you a simple comparison ... So you will see my point. SWR is for RF what INFLEXION is for voice. Not quite but enough to make the point. Comprende Pa
This reminds me about a discution about hole propagation in semiconductors This chap could not imagine that a "hole" could propagate thru solid mater In principle you are right. And this is the "cons
Thanks Blake :) In respect with the nasty neighbor, we are living in NY :) Here everything is possible. Lucky with an understanding judge. I just wonder why my original post did not make it to the li

Many people have sent me comments about my unusual signature. I collect them and perhaps sometimes I ' ll publish them under the title "Americana" :) Meanwhile I thought to take a break from the dail
EXACTLY my friend. This is the IDEA behind my signature. You will not believe how many comments I got that indicate that the reader is either illiterate or he/she have been brain washed. The low read

I got lost yesterday in the hills of Yonkers. At a stop light, I looked at a 300 foot Radio Station tower. Somebody was climbing it. It just appeared to me that he was doing it too fast for a human b
When it comes to HAM Amps antenna switching relays, you will be better off in the long run by getting rid of the initial manufacturer components and build the entire switching system your self. I kno
Usually, we do not need QSK. And the sequencing is done by the processor so it comes "free". It is easier to integrate the named relay than a vacuum one. This is not to say we are not using, now and
BCD or Binary Coded Decimal is same as HEX only it rolls over at "9" Thus, you have to decode 9 combinations of 4 bits. Not hard but hardware intensive as diodes take a lot of space. You need pull-up
If any one needs some Micro Control I will be glad to help. I use for this purpose One Time Programmable (OPT) 8051 which can be an overkill for some applications such as the BCD decoder. If you feel
