7 am settings gary mitchelson, n3jpu, has done some interesting tests with the am settings and found some settings that work much better than the defaults. The parameters that sound the best are: po set to 25, mic gain to 40 to 50 and carrier level set to 225 (f51 menu). You can hear a sample of his...
8 atas-100 autotuning the tuning behavior of the atas can cause confusion unless you understand the algorithm it follows to find a good position. Normally, if the atas is installed correctly and it successfully autotunes itself, it will always go in the correct direction when you press in the tun bu...

13 disclaimer: the following procedures can possibly void your warranty. What's in there? (and a little on how it works) the stainless steel whip is mounted on top of a loading coil (under the rubber boot). The coil consists of copper wire wound around a "grooved" fiberglass rod. Part of the reason ...
14 in. This base assembly is secured with pins and would be hard to dissemble without damaging. Inside this is an rf choke coil (i'm not sure if it is air wound or on a torrid) that makes this whole antenna dc grounded. This protects the radio from damage from whip contact with power sources, static...
15 atas-1/atas-2 settings menu item 61 is has several settings for controlling the way the atas100 antenna works. In the user manual, there are several errors describing this function. On page 14, the instructions are correct and the easiest way to remember the correct settings are: atas-1 = one ant...
16 cwid with arts the cwid feature appears to have a bug. It sends out the 'w' as a 'u' in morse code. The cwid feature, when enabled, transmits a cw identifier every 10 minutes when the radio is operating in arts mode. Here is a set of instructions on how to test if your radio is affected: go to me...
17 must show enc for the ctcss tone to go into memory. If the main display does not show enc when the frequency is put into memory, the ctcss setting is not stored. Duplexers the atas100 is designed to tune on all the bands on which the radio transmits including 2m and 70cm. This requires a duplexer...

Changing the feedline length has also helped in some cases, but this seems to move the problem around more than solving it at the root ca...

20 after the factory mod. The swr icon with an 'x' next to it indicates that the swr is out of range. If you see an swr icon with an 'o' next to it flash momentarily, it is an indication that the antenna has finished tuning and the swr is 'ok'.

24 after modification there is also a software work-around to get the fans running on 2 and 70 on rx only, by using the 'spl" button and vfo a/b to turn on the split function.: • set the vfo "a" on the rx qrg on 2m or 70cm band and vfo "b" on a tx frequency on hf or 6m. • briefly press the tx ptt (w...

If these limitations are important to you should consider the ldg at-11 autotuner. Firmware upgrades a common question asked regarding the ft100 is whethe...
26 there is also an fcc site that has manual, schematic, and other information related to the submission for approval by the fcc. Unfortunately, this information is quite out of date since a product is normally submitted to the fcc well in advance of its actual availability and the manual is often j...

Playing around with rtty or afsk mode settings on the ft100 will only cause confusion. Sandor also used 1:1 600-ohm isolation transformers on the tx and rx lines as well as an opto-is...
