Built the audio section the first evening. It tested good as per the instructions. The next evening I finished the radio. Connected two 9 volt batteries and and tuned in many shortwave stations. I received many stations. It took me only minutes to get a feel for the controls. I will be doing the mods soon on the radio. I am very happy with the whole experience. Thank you guys for the really nice kit. I have already ordered the other 2 radio kits you sell.

Firstly, let me say that this is a great kit. For the price of admission, you end up with an adequate shortwave set with a low parts count. That being said, anyone who wants to use this radio for anything more than casual listening really needs to perform the suggested modifications laid out in the manual, those being replacing the RF gain trimmer on the PCB with that of a 10K potentiometer as well as adding an additional 10K pot w/1M resistor in parallel with the main tuning pot as a fine tuning control. I ended up acquiring the best results by replacing the 3/4 turn 10k tuning potentiometer with a multi-turn pot for coarse tuning and a standard 3/4 turn 10k pot for fine tuning. I also ditched the 100k trimmer on the board for regen calibration with a 25 turn trimmer. Not a necessary mod but it did make dialing the regeneration in a little bit easier. Speaking of dialing things in, you are going to want to have a digital shortwave receiver handy to properly adjust the tuning coil. While there are points on the board for an external speaker, I did find that the two speakers I wanted to use were a little too much for the LM386 amplifier to drive to a desirable listening volume. Not a big deal but I felt like I needed to point it out. This radio is great for broadcast SW listening but I'd be lying if I didn't say that copying CW and SSB on it isn't a bit of a chore. I guess this digital kid doesn't have the safe cracker's hand necessary for optimal tuning with a regen receiver. That being said, I can't recommend this kit enough. With that, if you are willing to spend an additional $25 or so on antenna connections, knobs, extra pots, and a case, building this radio is a fun and rewarding experience. If you're wanting something with a little more polish and a finished enclosure, the 1253 might be a little more your speed.

I built this radio and I turned it on. The first thing I noticed was that it squeals really loudly. I double checked all parts placements, checked for shorts and cold joints, grounded it properly, and had a long random wire antenna attached to it but the squealing did not stop. The audio is barely audible because of the horrible squealing. I've tried adjusting everything but the the squealing will not stop. When I called Ten tec, all they told me was that I needed a longer antenna.

This is a great kit, regardless of experience level. It reminds me of the shortwave kit radio my brother and I built in my high school days back in the 60s. The audio quality and sensitivity are excellent. On some stations, don't be surprised if it performs better than a much more expensive receiver. Spend a little time adjusting the gain and regen trimmer to make sure you get to experience this kit's potential. I've begun researching regen receivers in anticipation of creating my own. This will be my reference design.

It has been a number of years since I built a kit but this radio had good instructions and everything worked the first time I tried it.

I followed the instructions..it all worked good. Nice unit if you want to get started or just to play around with s/w. Might get you interested in something bigger and badder??

Wanted something to do for fun and was not displeased. Resistors all colored nicely and had no issued with directions.

Your kit #1054 is great but the colors on the resistors are not so good ,The Yellow and Brown are the worst. I reverest part #R12 and R11 and will go to Radio Shack and pick up the resistor,s as taking them out I droped them.

What value for money. I bought this kit for my grandson as an introduction to shortwave radio. Assembly is straightforward and the step by step instructions are simple enough for the novice to follow although you do need to have some experience soldering. Like all regen receivers tuning takes some practice but once mastered you will be amazed at the performance of this simple receiver when connected to just 30 foot of wire (and its much more fun). The instructions contain useful tips on how to add RF Gain and fine tuning controls. Once done this little radio gives expensive sets a good run for their money.
If you are starting out in radio construction then this is a great first kit. At less than $40 you wont find anything better on the market at this price.
