What kind of antenna do you propose?

Regardless,  a lightning arrestor and ground rod that isn't bonded to the service ground is still better than not having one at all!

I encourage you to try a bug. Vibroplexes are of course the classics. I think that the Vizbug (I have the right angle model) is an excellent bug and is easily adjusted down to 12 wpm or even slower with the vertical version which I think adjusts right down to 8 wpm. But why use a bug at 8 wpm?

I have a Vibroplex Lightning and an Original, both about 50 years old and just about like new. I found them cheap on ebay.

I also have a couple of high end bugs, one a Begali and the other a double-lever GHD.

You have to fiddle with a bug for a while before you can send well with one, but it's a very enjoyable challenge. It's more physical than using a paddle and thus much more fun for me.

It seems to me that some bug users don't match the dit speed of their bug to their sending speed so the code always sounds very rough and choppy. The familiar ratio of dit to dah must be respected if you are going to send beautiful code.

Paddles do have the virtue of making it easier to send code well. I often use a single lever paddle with a built-in keyer as if I were sending with a bug. So I tap the dah side for each dah. At somewhere above 25 wpm the built-in keyer and my built-in bug start to disagree. That's the beauty of the bug, your dahs and your spacing are all custom-made creative products.

Here is my predicament: I live in a townhouse, roughly in the middle of 12 homes. Our service comes in at the end unit. All of the meters are there along with the service ground. The rest of us receive our AC via what I'm guessing are feed lines running under the slab. We have no basements or crawl spaces. I know very little about electrical code and have no info on my home's setup-just what I can see, what I don't see, and the rest... all guesses. I cannot find any sort of ground rod near my units foundation. If my house is individually grounded, it must be beneath the house and inaccessible.

I live in Florida. I'm not downstate in "lightning alley" but I am on the Gulf and we get some pretty violent storms-far worse than anything I ever experienced living in the Midwest. I want to do everything I can to protect my yet to be installed antenna. Everything I read says that my antenna's  ground rod+lightning arrestor needs to be coupled to my main AC ground rod. This just won't be possible for me. Also, our soil is mostly sand.

Does anyone have any advice or suggestions? How great will my risk be with an antenna ground that isn't coupled to the service ground and what are the consequences?

I am trying to refurbish an old Gonset G76 but someone removed the vacuum relay from the power supply.
Can anyone suggest a replacement I could use that is commonly available?

I'm a new ham.  I got my ticket a while ago but 2 meters just wasn't that interesting.  Saved up my nickels and dimes and got an Alinco DX-SR8.  Spent a lot of time listening but I didn't key the mic because I didn't have a proper antenna.  Finally I got an end fed quad.  Yay!  Now I have 100 watts and a wire.  Kinda basic but way more than enough to be a real HF ham.  Listening on 20 meters a guy in Spain is coming like gangbusters  5 9 plus.  Working stations all over the USA.  I wait and listen, wait and listen.  Then there is a lull and he calls CQ.  I key the mic and give my call sign.  No response. Again, same thing.  I guess he just didn't hear me.  OK fine. So i try something else.  I find quiet spot on the band and call CQ.  Over and over.  Then I notice that the ammeter on my power supply never goes past 2 amps when I talk. 100 watts would be over 7 amps. A quick check with the antenna analyzer says 1.2 match.  So I can only think of 2 reasons why I am not getting out.  One would be not enough microphone gain and two would be a problem with output transistors.  #2 doesn't seem likely since I haven't keyed the mic until now.  You guys have any ideas?  I'm going to read the manual and see if there is a way to up the gain.

Hi. I have a 7300 (and a lot of other Icoms), and really enjoy it.
I think scenario #2 you listed, is already in the works. On the 7300 Yahoo group this has been discussed several times.
The existing 7300 can be improved in software, but most 'complaints' about the radio center around the single antenna connector, etc. So scenario #1 may not be in the cards.

I was bored the other day and I got to thinking about Icom's model numbering....
There is:


What about a 7500 or 7900? 7351?

Pretty trivial, but to this old fart, kinda fun to think about. I bought my 756PRO in Tokyo the week it was announced, then came the PROII and PROIII. The only complaint I've ever had with my PRO is the lousy NB. Even my older Icoms are much better there.

Hello Glenn -
 Thank you. I didn't even know about what Menu 20 can do. I will try that as a maintenance procedure. The latest is that I added the lubricant as best I could and left the assembly in a vertical position to help the oil work its way down the motor shafts.
 I then installed the AT, tried it, and it seems to work. No squealing and it tuned the antenna like before. Hopefully, it has been repaired. If so, I just saved some money and have a fully functional rig again. Thanks again for the advice.

Kind of nice to see this:
"A long time ago, ICOM decided the S-9 = 50uV @ 14mhz was the standard they would hold. Hold it, they did..."
At least it's a defined and consistent reference point (linearly preceded and followed or not).

On a different/larger subject, what's the thinking on how long it will be before:
a: Icom decides the uptake is so good on the 7300 that they ship a 7300 II with a few notable improvements?
b. Icom ships a big brother to the 7300 with some very significant improvements?
c. Kenwood ships something similar/better in response to the 7300?
d. Yaesu ships with something similar/better in response to the 7300?

I signed up for the Yahoo 7300 group (the one that has about 1900 members) but I didn't find your reports.  It's probably user error (I don't find Yahoo's forum software to be the most modern feature rich and user friendly so maybe it's just my lack of Yahoo search and navigation skills). 

You are in the right Yahoo group. Do a search in the group for his call letters and you will find what you are looking for. The Search Conversations bar is at the top..

Thanks - that works.
