The antenna is a 7 to 30 Mhz AlexLoop. A lot of QRP operators favor one. I haven't used it enough to decide if I like it or not.
Setup of the SignaLink was pretty straightforward.
- Using the Allen wrench supplied, remove the front and back panels from the aluminum enclosure.
- Carefully align the jumper module and insert it.
- Reassemble the case.
- Connect a 6 pin mini-DIN to RJ45 cable from the SignaLink to the rig's DATA port.
- Connect an audio cable from the SignaLink to the rig's speaker jack.
- Connect the USB cable between the SignaLink and laptop.
- Since I want rig control, I connected my Valley Enterprises USB CT-62 cable between my MacBook Pro and the rig's ACC port.
Once everything was hooked up I changed the rig from VOX to PSK31-U data mode, and in Fldigi, selected the USB AUDIO CODEC for sound input and output.
Below, I'm monitoring a PSK31 QSO in Fldigi.
I played around with this setup for about an hour and was able to receive several signals. I called CQ but did not make any contacts. I gave up when 20M died.
I was impressed with the ease of setting up the SignaLink and wish that I'd bought one awhile ago. It's easier to adjust than the internal sound card.
The MFJ-4103 power supply looks like a good buy, also. It looks like a laptop power supply and would be a good choice for anyone traveling with an FT-817ND or using one as a base station where there is 120VAC power.
