My Kenwood TS-2000 HF/VHF/UHF All Mode Multi-Bander
Shown just after completing LED Display Modification:
LED Display Kit - convert your TS-2000 from bulbs to solid state LEDs!
-current draw only 60 mA (bulbs 350 mA total)
-the LEDs will not burn out and provide a whiter light
Why would anyone want to replace burnt out bulbs with OEM bulbs???
Kit (6 LEDs, 3 smd resistors, solder, solder wick)..... $30.00 (includes USPS first class
shipping USA). Specify white or yellow (original color)..

Elecraft (and other) Kit Building Services
Ask
me about custom building a K2
(or K3?) for you (***$500.00 for a K2/100)
-I will build any kit and it will look like it was factory assembled. Surface
mount devices are not a problem.
-Alignment of your K2/100 is available at a cost of $100.00 (includes using Spectrogram
to align filters).
-Repair, building, and/or modifications: $20.00 /hr + parts and shipping.

7- Heathkit HW-5400
8- Epiphyte 3, A 75 Meter SSB Transceiver
9- AT Sprint 3A Micro 4-band CW Transceiver
***Includes
the use of high quality IC
sockets, silver bearing solder, cleaning
PCB's of all flux and
residue, and alignment of filters using PC and Spectrogram.

Softrock Lite + XTall v8.3 Kit
(excellent reception using your PC, software, and an antenna)
-Uses a Si570 I2C Programmable Crystal Oscillator that can be
controlled via PC USB port!
-Covers 10 - 160 meters via 4 plug-in modules
-Recording will actually let you actually receive anywhere on the band
during playback!
This SDR Receiver will be neatly mounted into an aluminum diecast
enclosure with jacks to the outside world.
Lite + XTAL (Si570) v8.3 with USB Interface Add-on:
Completed Projects:
-K2 Transceiver (Ser. #501)
-K2/100 Transceiver (Ser. #2786)
-K2/100
Transceiver (Ser. #3759) for KK9H on 11/15/03
-KX1 Ultra Portable CW Transceiver (Ser. #0158) for
WN1FVQ on 12/02/03
-KX1 CW Transceiver (Ser. #0371) for K2YT
-Remoting a KPA100/KAT100-2 into an EC2 (K2 Twins Project) for
KS7J.....August 8, 2004
Used K2 Ser. #2786 which
I
originally built.
-K2/100 (s/n #2721) "tune-up", along with remoting the
KPA100 into an EC2 enclosure with a KAT100 for KL0SW. The K2 will
have a KIO2 installed along with a KAT2 and
a KBT2 (Battery Option).
(December 4, 2004)
-K2/100 (s/n 4956), and a XV144 for LA2CFA (received on
05/31/05)on July 1, 2005.
-KX1 (s/n 1458), for WD8NJR (Oct. 2006)
-Wilderness Sierra w/ KC2 and BuzzNot Noise Blanker for NE1NH (with a 40M band module).......(Nov 2006).
-Updated K2 (s/n 2721) with KDSP2 DSP option. Also finished a KX1 (s/n 1437 w/ KXB3080, KXAT1, and KXPD1)..all for KL0SW (Dec. 2006).
-Built an SW-30+, and a Epiphyte 3 for Rich KL7PB (Dec. 2006).
-Custom built an AT Sprint 3A micro 4-band CW Transceiver for an amateur in Japan.
-Completed another Wilderness Sierra w/KC2, BuzzNot NB and 3 band modules for NE1NH (August 2007).
-Repaired (+LED Kit) a Kenwood TS-2000 for a radio club in Winston-Salem, NC (August 2007):
Receiver was intermittent about 5 minutes after turn on. Q1 (RF mute transistor) and R2 and R3 (bottom of pcb) fried on the TX-RX 1 Unit PCB. My guess is that someone actually transmitted into the transceiver!
-Installed an LED Display Kit into an amateurs TS-2000 (November 2007)
-Completed (April '08) working on a Norcal 2030 SMD Kit.
(A Low Power / High Performance 20M or 30M DC CW Transceiver...)
-Completed (November '09) K2 Serial Number 3023 (Troubleshooting, adding KSB2, alignment) for NV8DM
-Repaired/ aligned K2/ 100 (sn #3595) for Bert (WA2SI)...unstable VFO.

575-M6 Hand Held Microphone
6- As of May 8, 2003: - Transceiver updated with all mods, and filters tuned
using Spectrogram.
-Most IC's are installed into high quality
sockets for easy removal.
-Used Kester "no clean" Silver Solder. Flux removed from most of the
PCB's.
-Crystals are grounded as low as possible to the pcbs.

SSB and NB Option PCBs:
-Use of a 20-turn Pot for SSB Carrier
Balance
KPA100 (100 Watt HF RF Power Amplifier)
KAT100 Auto Antenna Tuner w/KPA100
-I have built 2
of these units. One was mounted in its own slimline enclosure, and the other was
a "K2 Twins" version mounted in an EC2 with a KPA100 100W
Amplifier.
