KH6HTV is the call sign for the Boulder, Colorado Amateur TV repeater.   It is a cross-band repeater for 23cm & 70cm.   The output is on Ch 57 (420-426MHz).   The repeater is dual mode, capable of operating either in analog (480i) NTSC or digital high-definition DVB-T.    Complete details are found on my web site:  www.kh6htv.com     (rev. 15 Jan. 2018)

Jim Andrews, KH6HTV, "Maui Jim". I am a retired electronics engineer.   I have BS, MS and PhD degrees in EE from the University of Kansas in the 1960s. My early career (67-80) was at the National Bureau of Standards where I received several patents. I worked in the French national telephone labs, CNET in 1971-72 at the birth of fiber optics for telecom. I am a Fellow of the IEEE.   In 1980, I left NBS and founded Picosecond Pulse Labs.  Picosecond was a high-tech company specializing in ultra-fast risetime, pulse and pattern generators and also ultra-broadband (kHz to GHz) microwave components. The leading edge PSPL product was a 40Gbit/sec pattern generator and error detector. Picosecond  also designed and built 100 GHz bandwidth sampling heads on an OEM basis for LeCroy oscilloscopes.  PSPL was sold in January 2014 to Tektronix.  Tek moved all of the PSPL operations from Boulder to Beaverton, Oregon.

I and my wife Janet live in Boulder, Colorado during the summer and in Pukalani, Maui, Hawaii during the winter. From Hawaii, I mostly operate HF - SSB (40-10m) or BPSK31.   PSK is my favorite HF mode.   The rig is a 100 watt, Yaesu FT-857.  The antenna is a multi-element, fan dipole for 40/20/15/10m at 7 m.  With this modest antenna, I am able to cover the Pacific Rim.   My official, FCC registered, KH6 winter address is listed above.

In Boulder, my HF station is a 100 watt, Yaesu FTdx-3000 with a Heathkit SB-220 HF, KW, Linear Amplifier.   I recently moved to a new qth in Boulder.   The new qth has 2 1/4 acres of land and a pre-existing 50 ft. tower.   The HF antennas are a hex beam (20/17/15/12/10m) at 15 m, plus fan dipoles -  80/40/30m at 12 m &  20/17/15/10m at 9 m.  I have antennas for 80 meters thru 5cm (5.6GHz) on the tower.   In Boulder, I am mainly active on the UHF & microwave bands with fast scan analog (480i) and high definition (1080p), digital TV.   I run analog, VUSB-TV on 70cm, FM-TV or 23cm and hi-definition (1080p), digital, DVB-T, Television on both 70cm and 23cm.   I designed and built the Boulder TV repeater.  The repeater is on the 70cm & 23cm bands and covers the eastern 1/2 of Boulder County.  The repeater is both analog and digital TV on 70cm & 23cm bands.  I am active in the Boulder & Maui ham clubs, and the Boulder ARES group, BCARES. Since 1997, I have been a volunteer ham TV technician for the Boulder Sheriff's SWAT team.  Due to old age, I recently retired from the swat team. 

In 2011, I started a small business, KH6HTV VIDEO, to design, build and sell Pre-Amps, TV Transmitters and RF Linear Power Amplifiers for the amateur radio market. I offer equipment for the 70cm, 33cm and 23cm bands.   Complete spec. sheets, along with a selection of over 35 TV application notes are found on my web site: www.kh6htv.com

I like to write technical articles and have published a lot over my career.  For ham radio, I have published articles in QST, ATV Quarterly, and our local ham club newsletter, BARC's Bark. I also was the BARC newsletter editor for several years.   My most recent QST publication was "DVB-T:  A Solution for ARES Television Operations", QST, June, 2015, pp. 42-45

73s & Aloha -- I hope to chat with you on the HF bands from KH6 land or see your P5 ATV videos in Colorado (W0 land).

QSL info: I am not into contests and do not collect QSLs for awards. I prefer long QSOs instead of just short "599 - 73" contacts. I realize many hams do collect formal QSL cards for contests and awards. So, if I receive a real QSL card from you in the snail mail, and confirm it in my log, I will mail a real QSL card to you. If you want a faster response with an electronic, .pdf,  QSL card, send me an e-mail request to kh6htv@arrl.net   For HF contacts between May and October, they are from my Boulder QTH and QSL cards should be addressed to my new qth at --   KH6HTV, 1025 Paragon Drive, Boulder, Colorado, 80303, USA.
