Don’t expect a small, low power handheld unit to do the job of a 5 watt handitalkie–it won’t.
The transmitter output could probably be designed to match the antenna and add the necessary inductance to bring the system into resonance without adding a dime to the cost. Could that have been manuzl the repeaters were nearby and very good machines? But then, hams have always tinkered to improve nearly every piece of gear that ever hit the market, usually because in someone’s opinion performance could be should have been!
It didn’t perform poorly for me at all. I know there are lots of hams out there that own this little radio and love it for their particular uses.
The antenna connection is made by means of a gold-plated spring contact. Remove the three screws on the upper rear cover, and the four screws inside the battery compartment. This is all just my opionion and I thank everybody for their opionions. Also another point, I’m not knocking the DJ-S When I had mine I lived in Florida and later California. I made a “body wire” dj-x11 of it.
Yeah, that would be good if you could post your field strength results on the page. I personally feel that Alinco could of put a compact decent antenna on there yeiding better results like other HTs.
How do you know the antenna isn’t resonant? I got into all the local repeaters just fine. Honestly there wasn’t much difference at all. 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.
How does one know if an antenna is matched to a radio?

I use a mobility scooter and the low power does not interfer with the electronic controler. I realized that I could hit all of my nearby repeaters with 50mW on low, in fact, I could hit repeaters on 50mW that I couldn’t hit with mW with just the plain whip. I got my Icom T7H to do just that. But honestly, if you’ve owned this radio, can you really compare it to the performance of your other duckied HT running low power, or atleast the receive factor?? Thanks for submitting this article.
It’s an endless game, and most of us enjoy playing it to some degree! This will allow you to use either an SMA duck or some other type of antenna.
Carefully remove this resistor, using a small tip soldering iron, tweezers and a steady hand. The space shuttle operates with a 7: I’m well satisfied with my DJ-S They loaded up just fine and radiated quite well.
It is bad enough trying to sift through all the spin that the “advertising specialists” read that as controlled liars put into the ads but when we have to see if a HT has a resonant antenna with it.? To further prod you further, can a ohm folded dipole be resonant? I think the radio has a good cosmetic shape and is very light.
My old HTX ran circles around it with a smaller duck antenna. The antenna had no loading and I didn’t notice any loading on the inside.

But don’t you think that you would of appreciated your HT better if it had comparable performance to your larger HTs on low power settings??

If I understand basic theory correctly, max xfer of energy is when source impedance equals load impedance. Please remember that these were mW HTs. I personally don’t have any way to measure SWR with this radio obviously or what impedance this antenna is acutally at.
Possibly because the radio worked well enough the way it was designed for the purpose it was designed for. 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 got my 2 mtr pocket radio second hand and didn’t expect too dj-s11 out of it, the one I got had the telescoping 10 inch whip. Icom cancelled this product on April 9, You guys have defenatly raised lots of good points.
