Amateur radio kits

Ham radio links related to kit building projects. Many ham radio operators enjoy building transceivers, tuners, keyers, and other kits and homebrew projects.

K1EL Systems – Amateur Radio Kits and Projects

• K12 Keyer IC and Kit – The K12 replaces the very popular K10 and K10+ keyers which have been shipping for almost ten years now.
• K10+ Keyer IC – The K10+ is a Morse keyer I.C. with lots of built in features only found in high end keyer I.C.s.
• K-ID and K-ID2 – This chip is designed expressly for dedicated beacon or CW identifier applications. It is very flexible and has the advantage of a very large message storage bank (512 bytes) which is non-volatile.

• Brand new appealing Radio skin with true VFO.
• Multiple skin options. Currently two skins available. (See Bill Walch HS 2.0 version here)
• Improved DX cluster
• Simulation on/off switch
• Improved warning system / Ban / Kick
• Dual filters
• Monitor
• Memory channel / VFO operation
• Fast direct frequency to band setting.
• Realistic VFO with 10 hz resolution.
• Progressive VFO for fast and reliable tuning.
• Fully implemented jitter buffer to minimize audio latency. Can be switched off for fully reliable audio stream.
• TCP protocol transport. Will work through most firewalls (unless it’s blocking outbound traffic)
• Single channel NAT-friendly TCP/IP operation.
• All HAM bands included: 10, 15, 20, 40, 80, 160, WARC bands + BC band.
• Better audio compressor.
• Better audio bandwidth (up to 4 kHz).
• 32kbit audio codecs (Application will require 32kbit up and down stream).
• Fully realistic analogue S-meter with dB scale.
• Instant band shifting
• Improved bandscope.
• Improved Ionospheric simulation.
• Same modulation technique as before. Hamsphere uses Digital Local Oscillators and true DSB modulation.
• Limited tranceiver for guests (Limited band, power and filters)
• Subscribers enjoy; DxCluster, Full power, unlimited bands, audio codecs, noise free bands if needed.
• Subscriptions only for real hams and serious “11 meter DX ers” that have to pass a test and a user agreement.
• Broadcast band for broadcast people. Will not interfere with QSO bands.
• Robots will be on demo and DX bands only. No QRM on rag chew bands.
