4SQRP HF Test Set
|
davemrtn
I have had the HF Test Set kit for a long time and today I was digging through a box of un-built kits and found it. The board is stuffed now and I was studying the schematic and I must say this is a great kit with great features for testing hf transceiver kits. Too bad it has been a loooong time since it was retired. Documentation is still
available in the 'retired kits' section of the 4SQRP kits
page. -- David Martin - NA1MH - Mountain Home, Ar. ----------------------------------------- Wherever I go, there He is.

Hello Dave We were thinking about Updating it and offering it again. Possibly in a case? 73 Johnny

Thank you for bringing this to my attention. I for one would love to build this kit and could certainly use the test equipment. If you are not going to build it let me be the first to say I will buy it from you. On the other hand, if you are going to build it let me put my vote in for starting this kit all over again! Anyone listening to this reflector? 73 Bill Bill Fogel AG5SK 2500 E. Business Hwy. 83, Lot 264 Mission, TX 78572 956-424-5625

Music to my ears, Johnny. Let me know when and the order will be placed.

Ok Bill From thinking stage to kit sales could easily be 6 months!! Takes a lot of planning to put out a kit. 72

If current 'proud' owners of a HF Test Set were ask, I wonder what (if any) additions or changes would be on there wish list ??

Hello David. I own a original one that I use. I have some wishes. A rotary selector switch to choose the options, so one set of probes. A case with the display mounted in it. Possibly a RF signal generator, this may be asking a lot? Possibly ardunio control instead of a rotary switch, using a encoder and menu, hmm getting fancy now?? 72 Johnny

Hi Bill, IIRC. NM0S was going to take a look at modernizing it, knobs circuitry , etc. ad you can imagine he has been extremely busy with Ocon and FDIM Heel get to it im sure when time becomes available. Tnx for the interest

I find this makes it a lot more user friendly. I then installed LED's in the front panel as indicators for which function I'm using. Plus I put a jack on the front of the case in which to plug in crystals for the crystal oscillator. -- Tom Sevart N2UHC St. Paul, KS -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Tom, do you never use more than one of Test Set devices at a time ? NA1MH Sent from my Verizon, Samsung Galaxy smartphone

Hello all, Just want to drop my two cents worth in. A sweep generator and small screen oscilloscope would be wonderful. If the ardunio control is included, please make it optional so the non-ardunio ham could still use it. 72 Billy N5SE

Put me on the list for one or more. Thanks, Tom N5AMA

But next to the crystal oscillator section on the front panel, I have a switch to turn on the counter. Other than that I've never had to use any of the other function at the same time. -- Tom Sevart N2UHC St. Paul, KS -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Excellent idea to provide a useful tool to kit builders and homebrews.
Seek to add an LC measurement capability. NJQRP once offered it in Elsie, maybe George Heron could be asked for coding help. I suggest aiming to fill in gaps between what nanovna and tinysa offer, and focus on less tech savvy builders. I still use hftestset and Elsie. Curt

If an Arduino is part of the system, it won't be anything you'd have
to be concerned with. It's like the microcontrollers in modern
radios (or refrigerators, microwaves, washers, dryers,etc). They
are there to provide functionality and no programming or other
computer skills are necessary to use them. In fact, the original HF
Test Set has a microprocessor in it. No programming (by the user)
was required. Hope this puts your mind at ease.

The LC meter feature would be a great addition to a Test Set.
If an Arduino or just a bare ATMega328 is being used to control it, adding the LC meter feature wouldn't be hard. I did one as a "proof of concept" a couple of years ago, using an oscillator circuit similar to that employed in the popular AADE meter, an Arduino NANO controller, and an I2C interfaced LCD display. For those that are interested, I've attached a schematic of the oscillator as well as my Arduino code. It only uses 27% of the program memory and 27% of the RAM, so it can fit with other applications. Jim, N5IB

People want a nice HF Test set with an applications guide to learn from
We have nanovna, tinysa. So bring it on John ve3ips

Yes, this would be a wonderful kit to have for future kit building. Count me in. I've also seen some really good suggestions but I don't really even know what was included in the original kit so those in the know will have to be the ones to select, or not, any new features.
