26.805 FM Group

A reminder of a group we've featured on the blog before....

'The Original FM Calling Channel 26.805' on Facebook was formed 2 years ago to promote the use of the FM mode in North America and in that time has amassed over 3200 members from around the world.

They recommend 26.805 (Channel 23 on the low band) as an FM calling channel and when conditions are good you can regularly hear stations calling 'across the pond' to the UK and Europe so make sure you check them out online and on the air.

Thunderpole T-X FM Modulation Adjustment

Since revealing the Thunderpole T-X Debug Software I've had a sack full of messages asking how to adjust the FM modulation as some people say the audio is a little on the quiet side (That's those pesky legal specifications getting in the way!). So, you can do this AT YOUR OWN RISK, be aware that the radio may no longer be within legal specs, and be careful not to mess things up!

So open the Thunderpole T-X Debug Software, Select the correct COM port then READ from the radio.

Now SAVE a copy of your radios original settings in case you need to put the radio back to the way it was when it came out the box.

Find 'FM Modulation' near the bottom of the list. My radio's original setting is 217. Reducing this number will INCREASE the modulation level.

I set mine to 150 and the audio was noticeably louder without sounding distorted. You will just have to see what number is best for your radio by trial an error.

Once you have adjusted the level, WRITE the data to the radio.
