Maybe a piece of wire and a wing it is all that’s necessary for short range radios like this one. Once I did that, the radio came to life.
Why, because it is small, lightand easy to carry because of the flip up antenna. The display will blink if the VCO is taken out of its range. I’ve designed vhf transmitters to load into 1. Not too long ago a there was an article in QEX about this, a guy set up a way to test antennas on the radio with a nice HP network analyzer and had a neat little Smith chart for each one. I don’t dispute that replacing the antenna could or would increase performance, but to assume the stock antenna’s resonant point is the culprit is moot.
If your satisfied, that’s great. It is the only green component visible on the board. I cannot make the same comparison. Also another point, I’m not knocking the DJ-S I have the micro dual bander Alinco makes.
Around the clock, around the town, around the world.
Bottom line is that I’m not getting rid of them very soon. HTs are very difficult to check antennas with using test equipment as moving the antenna off the radio changes everything. Email Subscription You are not subscribed to discussions on this slinco. What if the radio is NOT of a 50 ohm design?
The thin board can be easily damaged by a high wattage soldering iron. I suspect that radios that do not have removable antennas may fall into this category.
When I second guessed the antenna design when the radio was still at his tailgate I probably should have left it there. It seems to me, especially considering you only owned the radio for a short time nearly a decade ago, that you had little or no factual basis for writing the article.
The SWR couldn’t be too high or they wouldn’t put out power they way they were supposed to. As a rule with modern Ham Radios that come out, you expect them to have near or equal standards of commercial radio equipment. Not bad at all. I followed the dj-d11 on the page and the radio has always worked alright for its price point.
Alinco DJ-S11 — Why?
HandBooks contain great info on transmission lines, SWR, and line loss. Using an Icom t7h nowadays. How does one know if an antenna is matched to a radio? Once I figured out that the antenna wasn’t loaded, I added the appropiate amount of wire to make it about 19 inches in total length.
The antenna had no loading and I didn’t notice any loading on the inside. The VX-1R is small too can do a lil higher power, but lets compare rx and low tx settings. Thanks for submitting this article. If it had come with a small tuned rubber duck antenna, I’m sure I’d still own it today. Possibly because the radio worked well enough the way it was designed for the purpose it was designed for. I discovered on my DJ-S11 is that the telescoping antenna had no loading, and I really didn’t feel that it was worth me modifiying it for what I paid for it.
The reason I wrote this is because I was cruising around online and saw that this product was still being sold new. So really, what was Alinco thinking? Yes, I know it’s low power and isn’t meant for long distant QSOs, but really, does it cost that much to put a electrically matched antenna on this radio?
I found no need to alter the antenna, although it would have been easy to put a 19 inch telescoping aerial on it.
My old HTX ran circles around it with a smaller duck antenna. After all, if you want a radio transceiver to reach any sort of distance, get one that will do what you want.
