The space shuttle operates with a 7: After all, if you want a radio transceiver to reach any sort of distance, get one that will do what you want. I never took it apart to check it since the radio seemed to work okay. The VX-1R is small too can do a lil lainco power, but lets compare rx and low tx settings.
This mod is for the DJ-S11T. I have mixed feelings about this review. 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. Newer ones contain information on conjugate match.
That said, I’m surprised that something as simple as matching the antenna was overlooked in their design. I was sure that I wasn’t the only one that had a gripe about it’s performance.
Therefore, rather than putting a below standard item on the market, the decision was made in the interst of our customers and dealers, to stop djs11 sale and advertising of this product. You will lose all of the memory contents.

Why, because it is small, lightand easy to carry because of the flip up antenna. Johnson Dentron Radio Co. After I did a lil antenna mod, I was fine, and even did better and the 50mw setting. I personally don’t have any way to measure SWR with this radio obviously or what impedance this antenna is acutally at. Never read that anywhere, maybe that’s why there is no connector stock.
Then we check the antenna to see if the impedance at our chosen frequency is close to 50 – 52 ohms. I agree the antenna is to blame for this tomfoolery.

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.
For what it was the DJ-S11 amnual well and I thought it was a good product. I’m just curious to what other amateurs have thought about this radio. They were very small antennas, yes, both short and narrow, and a small antenna is not going to outperform a larger one.
I was pleasantly surprised when I could use it to get into the local repeater from over a mile away.

HTs are very difficult to check antennas with using test equipment as moving the antenna off the radio changes everything. How does one know if an antenna is matched to a radio?
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.
This HT made me do a double take. Icom cancelled this product on April 9, The antenna connection is made by means of a gold-plated spring contact. Bill, why are you still worrying about this? I have the micro dual bander Alinco makes. Unless the radio was advertised to have a tuned antenna, there is nothing you can do about poor performance except convince others not to buy it. The output impedance of most solid state amplifier stages is low compared to tubes where it is high.
