Hi Chas. I've just measured my K400 mount and it protrudes 3mm. I reckon you wouldn't want any less than a 4mm gap. 0.165" is just a hair breadth wider than 4mm so although it'll be close it should be OK.
Thanks for the information. I feel much better. Chas. Don't forget that the coax cable shouldn't be squashed down to fit between the two surfaces. Sooner or later, continued squashing will result in shorting the coax and finally severing it. It isn't just the mount you have to be concerned with.

You've got to keep one thing in mind--the product in itself is supposed to not generate harmful interference, but each example of that product may have a small quirk, a bad part or a failed connection that could in itself cause interference. IOW, just because one of the product went bad doesn't mean they all will.
The gentleman in Florida with the defective well pump had been informed to have it repaired before--several times, but just ignored the warnings. THAT is why he was fined.

It's irritating, true. "In person" customers are there to buy and phone customers are only getting prices, FALSE! In case you haven't noticed, there are many people who do not live in driving distance of those stores that do their shopping by phone and internet. Talk about the 'me first' attitude rearing its ugly head!
I'll say this one thing--if you came to my store and displayed an attitude like that, I would take every chance I had to get away from you, and would cheer as you walked out the door. There is absolutely NOBODY who is more important than anyone else, and it's way past time you realized that.

You get what you pay for. There are many other threads on this site that list multiple pros (not that many) and cons (seemingly more) of such units. I had experience with one of the older ones that lead me to believe that these rigs are nothing but junk, but YMMV. 73.

You just have to laugh! Look at one of the recent feedback--
"5 out of 5: Great product, even went as far as removing the CD that could have a virus on it. I was going to toss it anyway, but thanks!"
Radio Mart probably took it out to try to sell it separately! Oh, brother!

Maybe they should be the dying breed, and no, I'm no salesman--and I don't want to be. All too many of them are money grubbing SOBs that would jyp their own mothers.
I rather have my fun by arguing over conditions or discussing contacts made rather than arguing over ten or twenty dollars. It seems that the only thing I agree with you on is that the pricing on the internet can't actually show you what the radio is like. Also, I do state that I will not negotiate--by saying $xx FIRM. 73.

Sometimes you can get a quieter wall wart from the cable company itself. Take the old one to the office and talk to a technician there. Explain what you're looking for and they may be able to get one for you. You may also try using an old CB power supply--a 12 volt 5 to 7 amp supply. Simply check the polarity of the connector, cut the wall wart off, and wire up the connector to the supply so the polarity is identical.

Besides tightening the screws, visually and mechanically check the connections that you can see. Sometimes a cold solder joint can be causing trouble like you have. It's doubtful on an Antron, but if someone opened it up before to check or repair it, it's possible.

...They also need to learn that the person in the store who came there to buy is more important than the person calling on the phone....
Excuse me, but just how do you come to THAT conclusion? A customer is a customer, no matter how he 'comes' to the store. If you're referring to the fact that when the phone rings, the salesman stops talking to the customer in the store and answers it, just consider that the caller may not be a customer and instead may be a supplier calling to update the store about a piece of equipment--already ordered by another customer. Sorry for having to say it in this way, but your comment smacks of the "me first" attitude that is pervading society these days. Just because you have to wait a couple of minutes more doesn't mean the end of the world is here.

CJS: Let me add: When I bought my new house one of the first things I noticed was the contractor had used the cold water pipe as a panel ground. From what I understand that was the code back in those days.
After living here for 20+ years I found that the copper water line extended just 12 inches outside the foundation! From there to the meter was PLASTIC! So basically, there wasn't a reliable ground on my system at all.
When I had an electrical contractor install a new 200A panel, two ground rods were installed outside as per the new code.
You would probably be shocked (pun intended) to know how many homes built in the last thirty years were built the same way. All too many electricians just connect the ground without testing the effectiveness of the individual ground they are 'using'. The real pity is that it's all too simple to test. When I did the regrounding at my present home, I was alerted to the fact there was a problem by the cable company. Yes, the cable company! It seems that when cable was installed, they just connected to the cold water pipe like the rest of the utility installers do--and the ground was backfeeding through their equipment! It actually melted the cable drop and damaged associated equipment so that there was a major problem on the cable system centered at my home! Luckily, I was told I didn't have to pay for the replacement equipment since the original installer should have checked the installation before he left--and he didn't. I don't think I want to know how much the bill would have been.

On the other hand, anyone looking for ham equipment online may already know what the going price for a rig is. With today's computers and smart phones--and the internet, it's easy to find out. Asking for more may cause that person to go right by your ad, no matter what you're asking and even if you're willing to negotiate.
I guess that I'm from a different mindset than you are. I won't offer a lower price to the seller who is asking near the going price since I believe that the person knows what the rig is worth in his view--and I mean how its been treated or if it's got any quirks or other problems. I'll simply ask if he could do any better, and if he refuses, I'll decide to move on or to buy.
Maybe I'm a dying breed, but I consider it a form of insult to be asked to take a specific amount less than I've got it listed for. I know what my equipment is worth and I'm honest enough to not to try and 'take' someone for more, or to waste someone's time bickering about a few dollars. If someone gives me a call or drops me an e-mail, I'm friendly--until I'm insulted--and even then, I'm not going to bite someone's head off, I'll just either accept or refuse his offer. I treat fellow hams the same way when I'm buying. Hey--If that makes me a 'grump' in your book, all I can do is to say "Thank you!" 73.

Considering that CB is AM, any decent power supply made for CB will have to be filtered as to not introduce noise on the radio itself. In any event, they're filtered better than the wall warts are that are so abundant these days!

Unfortunately, that 'delivery confirmation' just says the recipient got the package. If they file a complaint that the equipment was no good or not as advertized (what happened to me) you may still lose out.
Hey, the guy was dishonest, I couldn't prove otherwise, and I wasn't going to waste more money going after him. I was out not quite a hundred bucks--an expensive lesson, but a lesson nonetheless.

eHam Forums / Station Building / RE: Window Feed Thru
|
on: April 24, 2013, 03:33:45 PM

...I have a 2m/70cm vertical with an MFJ window panel and G5RV on the way. My plan is to ground the antennas and the window panel outside the window with a ground rod and then run a cable around to the other side of the house connecting the antenna/station ground to the electrical service ground. Is this the right solution? You're good so far... Alternatively, the house is old and has BX wiring (flexible steel conduit) and good ground everywhere, can trying into this ground suffice for connecting to the electrical ground? No, best not to do this. Keep your equipment ground separate and tie the station ground to the electrical ground at one place. Doing otherwise can lead to having ground loops which can be problematical to your station. If I add another vertical or tower I would ground that at it's location and it's feedline would be grounded at the station entrance, yes? If you put a ground rod at the tower or at the vertical, you'll also need to bond that ground rod to the other two, usually at the station ground outside the window. 73 and good luck!

Keep your eyes open at yard sales. Sometimes you see older 12 volt 5-7 amp power supplies that were used for CBs in years past. They're about the best because they're filtered and have plenty of capacity to run the modem.
