The Elecraft K3S at the Home QTH

I recently acquired an Elecraft K3S through an auction, and it's currently at my home QTH while my Icom 7610 undergoes repairs. The LCD on the Icom 7610 needed to be replaced and was fortunately under warranty. The other problem, while remotely operating it using software, there were connectivity issues where the radio would drop the IP upon losing connection. To regain access, a power cycle was required. Hard to accomplish when you're a thousand miles away, hihi.

The Elecraft K3 Upgraded to a K3S

In 2018, the factory completed necessary repairs and made modifications to the radio. The enhancements included DSP, KIO3BUPKT, KXV3B and KSYN3A as well as a NeoGrip addition to the main tuning knob. It's an impressive transceiver.

Now this transceiver has advanced DSP filtering capabilities and much more.

The KIO3BUPKT adds USB Sound and Com port capability. Also includes the standard KIO3 Analog and digital I/O.

The KXV3B option includes:

  • Receive-only Antenna Port
  • Intermediate Frequency (IF) Output and Input for Transverter connections
  • New for the B version:  Adds 2nd preamp for 12,10,6 M

KSYN3A: The Elecraft KSYN3A synthesizer upgrade for the K3 makes a dramatic improvement in local oscillator phase noise, resulting in improved receiver dynamic range and reduced
transmit spurious output near the operating frequency. Read more about this here.

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

I also just added a K3 to the lineup. I compared the close in dynamic range against my 7610 during this past weekends CQ WW SSB contest. The K3 is far superior. I heard weaker stations up next to the big guns on the K3 that were buried on the 7610. I also noticed that spatter on the 7610 is very annoying and harsh in the headset. I would never have noticed the differences if I had not been comparing them during a contest. Both great rigs though.
