Playing around with the X108 I decided to make a few comparisons against a few of my other receivers.

In the comparisons I have used the following:

Yaesu Vertex VX1700 with no extra filters: http://youtu.be/bJ_VN7S1PHM

YouKits TJ5A 4 band 20 watt transceiver: http://youtu.be/AAdPPSfl6co

The TJ5A is about 200hz low from the listed W1AW/KP2 DxSummit frequency and that on the VX1700 and X108, but the TJ5A has very little to no background noise and AGC works well.

Antenna was same antenna for all comparisons a OCF Windom for 80-10 at 30′

How long have I had my FT-8900? Four, five years, maybe? Of course I knew it received AM on air band and have used it on there from time to time, but it never occurred to me that it would work on 29MHz.

This afternoon, I noticed a tweet from Richard GW1JFV saying that he’d worked K1GUP on 29MHz AM and went on to say that he used his FT8900. I happened to be in the shack at the time and had the instruction manual to hand.

Menu item #45 was quickly found AM on | off – which allowed me to toggle AM on to 29MHz.

I fired it up and it sounds ok. Not brilliant on the monitor receiver – perhaps a little harsh, but it’s AM nevertheless.

Another option for using AM on 29MHz. Thanks Richard!

Update: Oh dear – this turns out to be wrong! The 8900 is receive only on AM. After an interesting conversation with Chris G3VEH, I checked this. Although the 8900 transmits when AM is selected, if you listen, it’s actually FM. When Richard made his QSO, his QSO partner must have slope detected his FM!
