Hi all, a coaxial line EM discharger is not enough when a lightning arrive on your antenna. I had a 8 meters long vertical antenna on the top of the roof. It simply exploded, I found several parts of

All well and good, but the ham radio control has never got out of the proprietary model and become standardised. This means we have a heap of systems, all incompatible with each other, no possibility

After a post last week regarding power spikes from the PTT switch, someone mentioned a similar problem with CW keying. There is indeed a brief spike at the leading edge of each dit and dah, with the

Here is a suggestion that could provide additional lighting protection, beyond the lightning arrester you should already have. I have multiple antennas, so I use a 4-position manual antenna switch.

Yes, Francesco. Always good to try if you are up to it. However, not knowing one's skill level, always better to err on side of caution. I know many times the feeling of satisfaction at having

It is possible for a bad board from the defective unit to damage a good board, so I wouldn't suggest board swapping using a friend's 7K. If two boards have visible damage from the lightning strike, it

I see.. Francesco The better is…. With another radio in good condition. Check all the boards one by one until you have complete sure which boards are damage. After that you will only buy what you

IZ2BKT has released a beta version of the suite BktRemote. I tried the version for Smartphone Android and, even if it is a beta, works fine on local WiFi network. With the Smartphone can use the

I certainly agree that it's good to use only the power necessary ( as does the FCC...), but I've done repeated thermal testing running 100 watts CW with the key down for 10 minutes solid, with no

Bill, I don't have any experience with the AT-180, but most autotuners tend to act strange when switched among a variety of antennas. There doesn't seem to be much band overlap in your setup, unless

I use my 7k at 50% when using FM, or less, depending on the repeater. Most of the area repeaters only take a watt or so. Remember that FM is 100% duty cycle, and most repeaters don't take much to key.

Guess I've been lucky. I bought my '7000 new in September 2008 (sn 0510369) and it still works great. I do keep a small computer fan blowing air softly across the heat sink, as it can get 'toasty' at

Hi Milo, I perfectly agree with you, time is important. But sometimes it's good to try, at least. Last month I repaired a power supply damaged with the same lightning that damaged the radio, and I

Thanks Ivan, I appreciate your suggestions. I posted that question exactly to know if it can be good or not to repair it. I asked to the service here in Italy and they gave me the radio back saying

For sure at least two boards have been damaged by a lightning. One is the RF unit, the one facing the lower cover. Another one is the small board with the KEY, ACC and DATA connectors. By visible

Ebay is sort of like Wikipedia; a bad start, bad quality control, but getting better all the time. I trust both now (but verify anyway). KC4BO Alex Netherton http://blueridgediscovery.org

Milo, I bought the radio in February 2013. I do run 100% power during SSB and CW contests, and no more than 40% on digital. I vary how much power I use when not in contests, and find that 70% is

Steve, The first failure was most likely caused by a short in a jumper between the IC-7000 and my AT-180 tuner. I have been meticulous about checking all of my feedlines since then, whether homebrew

Francesco, Take Ivan's advice. Trust me, you don't want to have to replace a board on your own. I can almost guarantee it would not be available, unless it was on the black market somehow. In which
