Hello Rob :)
Do not dispair !
I am sure there is help available 
Most all of us were in your shoes at one time 
I agree with John
Tell more about your equipment 
What type antenna did you build or have you not built one yet 
Why do you say stupid antenna ??
I have never owned a store bought antenna for HF use
But I think you can buy a factory built antenna cheaper than you can buy the parts to build one 
I figure there is a ham radio club somewhere in your area 
I agree with John more info is needed !

1.      What type of antenna are you making?

2.      What is the intended frequency of operation?

3.      Is it to be fed with 50 ohm coax?

4.      Is it a full size radiator or a shortened version employing loading of some sort?

Pleas provide some specifics and maybe I can help

What do you all suggest for a new ham to do, to check out the SWR on an antenna he just built?  I really don’t have many Elmer’s around me to ask.  I probably should make the stupid antenna and take  to the ham fest where I am taking my general exam and see if someone has one.

First thing is that for HF, one can only gain a realistic test where it
is to be permanently mounted. Surrounding objects that are close in
terms of wavelength will have an effect on it. Likewise, at the hamfest
the objects surrounding the antenna will be entirely different and
tuning it there will likely be incorrect to some degree when you get it
back home.

There are a lot of analyzers on the market. The current cool thing is a
Vector Network Analyzer, VNA. Some VNAs are stand-alone and some
analyzers have a VNA built in. I'm a bit biased as the Rig Expert
AA-230ZOOM is the finest analyzer I've used. To be fair, I have only
used the classic MFJ analyzers before buying it. When I worked for a
railroad, I had the opportunity to compare the AA-230 to a Bird analyzer
we had and to an Anritsu model. The AA-230 was right there with each of
those units.

The Rig Expert units are not the cheapest thing on the market. However,
they do have lower cost models that only go up to 30 MHz and so on.

https://rigexpert.com/

I would recommend the ZOOM models just for the lovely color screen.

Just the other day I used mine to do a simple check on some simple
Unadilla antenna traps.

Rob:
If your rig has an auto-tuner, you could probably operate without knowing if it is resonant or not, as long as the tuner is able to tune it.  If you don't have an auto-tuner, you might invest in a 4S-tuner, which should be able to tune almost anything (within reason).  Besides being able to tune the antenna, it includes circuitry to let you know the SWR is safe, but it doesn't tell you what the SWR is.

By the way, don't forget the Second Sunday Sprint is coming up this Sunday evening, as usual.

The BEST such device IMHO is the digital
Peak Atlas LCR-40.  If you like to build circuits
for ham radio or any other electronics activity, you
will find yourself reaching for your LCR40 more than
any other instrument. 
You can buy it from Amazon, for about $110.

Re: lcr meter

Jim I just bought a model BM4070 off ebay (NEW) for $26.95 which includes free shipping. It arrived in about 5 business days. I checked it out and it seems to be reasonably accurate on low value  (pf) caps. I haven’t used it for checking inductors yet, but I assume it would be ok. It even comes with a zippered cloth case for storage. Appears to be a great buy. I’m an old guy with bad eyes and those small caps are hard to read. I used my MFJ 259B to check a couple of questionable caps while building the Hill Topper and decided then that I needed a better way. That’s when I found and bought the BM4070. I think this will make kit building MUCH more pleasant. Hope this helps 72’s W3BNO p.s. the batteries are included

Re: SW Series transceiver repair

Bill

Please identify the crystal frequency and this can give us a hint on which band it is for.  Of course you can tune in a signal, and verify it is on 40m with another rig.  if all is okay with the receiver, I would recommend testing the transmitter with a dummy load - for very short transmissions.  can you hear it in a nearby receiver?  monitoring current as you key down is another piece of data. 

unless you have data otherwise - was the rig ever working?  usually someone would not install one of these into a case without it working, but I have seen a few exceptions. 

I can't look at it right away - with a little patience you may figure out what state the rig is in. 

Spotted your nice HW16 and U3S - I also have those sitting here.  If you can build and program a U3S - I have high hopes you can solve the SW-40.

Re: 40m Net

Dennis Yancey
 

Not going to despare, been at this too long to let band conditions get me down. My little rigs are doing great when the band lets us...

just a thought.. if I put a Wattmeter in between the radio to measure the output of the radio at 5 watts and before a 600 watt amplifier, would this still be considered QRP..... jk... 

if you cant hear them watts don’t matter..lol

Check again next week..and Sunday.

Re: 40m Net

Hello :)
I did not try for the net !
But :)
I think anytime the SFI gets a few points below 70 !
It is like someone flips a switch !
Any type other bad solar activity don't help nothing either :)
Anyway :) from what I see 40 meters can be like a ship in the middle of a stormy ocean whenever SFI gets a wee bit below 70 !
Not a single thing in earsight !
Just seems to be a point where a switch gets flipped off !
One thing for certain :) the band is kaput !

I listened intently to the nets myself but heard absolutely nothing. Could it be that the recent
solar events have killed propagation or possibly made the bands go long? What it is, I could not
copy anyone. I hope I do better next time.

This has happened before. I listened on 2 different radios and 2 different antennas..  any suggestions?
