Go on the TecTec reflector on and ask real TenTec users for answers. Sure beats the guessing games on this forum.

Time to restore the beast. Seems to RX and TX ok. I noticed the digital display only showed 14 in the proper position. (14n.nnn) I removed the counter board and re-soldered the connector pins. Now I have where the 4-7 is missing in the 3rd position. I believe the first 3 number positions are fixed with the 3rd position controlled by the band/frequency switch. Any input on the missing 3rd position?

(n-not lit and x=lit and correct value.

Thank you for reading.

Depends on the time of day you like to operate as well. There are a lot of morning operators that do fine without an amp. It can be pretty frustrating at night for both you and whoever is trying to copy you.

When I work 40 it is morning an into early afternoon and I am rarely barefoot. To me a amp is not as important on 20 and above for regular QSO's.

There are multiple structured and unstructured nets on 75 meters starting as early as 4 AM Eastern.  Many of those guys don't even own an amp and as long as there is no intentional interference they can be copied easily. Evenings, in the summertime especially, they are a chore to copy.

It could be a Terminating resistor. First thing to do is check it out with an ohmmeter. 600 to 800 ohms is a common value for terminating resistors used in terminated rhombics and the military used a fair number of those types of HF antennas.   ....and it could be a balun, if that is the case you would likely get resistance readings of either infinity or zero between terminals.

It makes perfect sense to me to connect an analyzer to an end-fed wire antenna, if for no other reason
than to determine the load impedance so you can design a matching network for it.  You absolutely
need the ground connection to do so.

If the analyzer only worked for 50 ohm loads then it would be useless, because the only time you
could measure an impedance you would already know it was exactly 50 ohms.

One problem, of course, is that the impedance of the antenna may be outside the range where the
analyzer gives accurate results, but that limitation applies to coax-fed antennas as well.

As long as you have the ground connection, then sticking the antenna wire into the output connector
of the analyzer (or using a banana plug) should work as well as anything else, except for any problems
holding it there while you take the measurement.

Alan:  Thank you for the additional information.  I don't always get SPAM from those who require email addresses or phone numbers.  However, I do get SPAM from those who buy this information. 

It's got so bad that I'm now paranoid.

It doesn`t bother me. What I am tired of hearing is,"KC2XXX for ID". When you say your callsign that`s a legal id. When I id on a repeater all I say is,"NO2A". No need to say "listening". Why? Because it`s obvious you`re listening,monitoring,whatever.

While I agree on the 4ID thing actually there is a need to say listening out of courtesy.

If you just give a call sign maybe your testing something, Maybe you just want to see if you can hit a repeater, maybe you kerchunked by accident and feel compelled to ID. "Listening" is sort of implying you anticipate a response. Almost like a CQ.

I'm somewhat confused here.  I've always been under the impression that a random wire was just that.  Random length.  And it had to be matched to a radio through an antenna tuner.

In this case the analyzer would be connected to the input of the tuner, the antenna connected to the tuner.  The tuner would then be adjusted for resonance. 

However, if the so called "random" wire was cut for a specific band, like for portable work, then the random wire would be connected via a PL-259 to the analyzer.  The counterpoise would be connected to the shell or ground side of the PL-259. 

I've never heard of this and frankly, I'm not sure if this would give any meaningful information.

Without any discussion about other posts here are my thoughts after 41 years of operating.

The 718 is a great little radio. Perfect for a beginner or an advanced ham. I have owned on since they first came out and I use mine daily on every mode except SSTV. I have the DSP and a CW filter. I don't find, after thousands of hours of CW ops, that I just have to have a narrow CW filter. The crystal filter sometimes amplifies the noise level to the point that it becomes tiring. I like to change the frequencies of the noise with an AF filter and emphasize the signal. That may just be me though.

The Yaesu 450D is likewise an excellent rig for beginner or experienced op. That rig also comes with a built-in antenna tuner that works pretty well. You really don't need to add anything to it to have a very capable rig. It also has 6 meters. Cost is a bit more, but then it has some things you'll have to pay extra for with the 718.

The Yaesu 857D is also a great all-in-one radio. You get most of what the 450D has, plus all mode capability on VHF/UHF. The 897D adds a bit more of the same plus the ability to operate self-contained from internal batteries. These two rigs require purchase of filters and a tuner. Some complain of small screens and multiple menus. I just buy a bigger monitor for home use. Very few people drag a Kenwood 990 with them on vacation.

Any of these will serve you for many years. Divide the costs by the number of years and they are very inexpensive over time. All four of these can be computer controlled with something like Ham Radio Deluxe making them super easy to use and offering capabilities you simply will never achieve on non "Ham" equipment.

In defense of cheaper equipment, I will note that these rigs can, and do, work but I think that after the new of ham radio wears off a bit, you will be wishing for more capability. Spend wisely.  73

it requires the use of M$ .NET framework client.
- which crashes on install under wine.

General Logger v8 by W3KM works better .
