I have been licensed since 1971. I started off as most did in those days with 10W AM on Topband. Next I tried 2M AM - who remembers those days of being crystal bound and tuning high to low on the receiver!

My current equipment is:

  • ​FTDX5000MP with SM-5000 Station Monitor and MTU 80/40 uTune unit
  • Elad FDM-S2 SDR
  • Yaesu SCU-17 Digital Modes Interface Unit
  • Explorer 1200 HF Amplifier - not used at present
  • Telepost LP-100A Digital Vector RF Wattmeter -  a lovely bit of kit from Larry, N8LP, much more than just a wattmeter
  • Inverted V dipoles for 60M / 40M / 30M / 20M with the apex at 8M

The FTDX5000MP is a superb rig, especially if you are a CW operator. The down-conversion design of the main RX means that the roofing filters can be narrow and sharp. The 300Hz roofing filter is absolutely amazing. The DSP is very very good. I have always preferred Yaesu rigs and the 5000MP is probably going to be one of the last of the large format rigs with lots of knobs and switches - which I personally love. I just don't like the modern trend of tiny rigs with multi function knobs / switches / touchscreens.

The Elad FDM-S2 SDR provides spectrum/waterfall display capabilities using the associated FDM-SW2 software (the SM-5000 is rather poor in this respect!). The RX capabilities of the FDM-S2 are very good when I compare it to the FTDX5000MP. I have it configured for two 384KHz wide data streams so this means I can monitor two ham bands simultaneously. I have written a custom Windows program to sync the 5000MP with the SDR so as I tune the 5000MP I can see where I am on the band spectrum display. For more details of the FDM-S2 go to  http://ecom.eladit.com/ELAD-FDM-S2

I plan to upgrade my antennas in Spring 2016 and bring the amplifier back into play. So hopefully my signals should be louder!

My main interest is Summits-On-The-Air (SOTA). I have so far amassed over 18,000 Chaser points but only 100 or so Activator points. For SOTA activations I either use a FT-857D or for QRP a YouKits HB1A. I wish I had more spare time to do Activations, which are tremendous fun. Good exercise climbing to the top of a SOTA hill carying portable equipment too!

Hope to catch you on the bands !
