about - KL7UW

Basic Ham Radio Info: KL7UW is located in Nikiski, Alaska 65-miles (98-km) southwest
of Anchorage on the west coast of the Kenai Peninsula. The grid square is BP40iq.

My name is Ed Cole and I have held the following ham radio licenses:
  • 1958 - Novice - KN8MWA
  • 1959 - Technician - K8MWA
  • 1982 - Advanced - AL7EB
  • 2000 - Extra - AL7EB
  • 2005 - Extra - KL7UW (vanity callsign)

  • How I got started and my first years in ham radio [page not restored]

    I have a station operating on the following frequencies:
    • MW: 630m
    • HF: 160, 80, 40, 20, 17, 15, 10m
    • VHF/UHF: 50 - 144 - 222 - 432 - 927 MHz
    • Microwave: 1296 - 2400Rx - 3400 - 10,368 MHz
    • Radio Astronomy Rx: 1420 MHz
    My Main Ham Radio Interests: I am mainly interested in weak-signal techniques such as long-range VHF/UHF/microwave propagation, amateur satellite communication, EME (Moon Bounce), Meteor Scatter, and Radio Astronomy. I operate on 630m as part of the ARRL Experimental Group.

    Here are some of the organizations I am a member:

    As of January 2021:

    • Photos and diagrams of the station.
    • The main radio for the station is the Elecraft K3. Photo
    • HF Amplifier is an Elecraft KXPA-100.
    • Elecraft KX3 serves as second HF/6m radio, portable/mobile, with 2m 3w transverter option.
    • Used Yaesu FT-736R multi-mode, 144 & 432, satellite capable radio; will used for FM, packet, APRS, and backup SSB/CW radio
    • 50-foot tower#1 supports the 2m EME array with four cross-element yagis. Nov. 2, 2020 high winds took down the array and bent the tower
    • The 2m-EME station running 1500w is usable for both tropo and meteor scatter.
    • A 45-element 1296 loop-yagi, 33-element 900 MHz loop-yagi, and 18-element 432 yagi have been moved to tower#4, pointed azimuth=060.
    • 50-foot tower#2 supports a 3-element triband HF yagi, two 11-element 222-MHz yagis, and 3-element 6m yagi pointed SE
    • Drake MN-2000 antenna tuner taken out of service as KAXT100 auto-tuner handles HF/6m tuning.
    • A 80m-160m-600m Inverted-L antenna is strung between two towers. Taken down with Tower#1
    • A 80/40m inverted-V dipole installed on a 50-foot HF tower attached to the east end of the house.
    • New LFA2 WOS antenna installed on 40-foot tower#4 for 6m-eme/ms using 50-MHz Harris Platinum 1000w Amplifier
    • Tower#4 also has two 11-element KLM yagis mounted at 45-feet
    • A 16-foot (4.9m) dish is used for 1296 & 3400 EME or 1420 MHz-RA. Removed for rebuild Oct. 2, 2020
    • I have a portable-rover station for use on 10,368 MHz.
    • Ford F250 4x4 diesel crew cab pickup July 26, 2016 with new Alinco DR-735T 2m/70cm 50w mobile radio.
    Future Plans:

    • Re-Install Tower#1 (probably to 30-foot) without Hazer; May require new concrete base Spring 2021
    • Repair and re-install four 2m cross-element yagis 2021
    • Repair dish back structure and build new mount 2021
    • Install new 1296 600 watt LDMOS amplifier and 50v PS at the dish. 2021
    • Modify Toshiba amplifiers for 50w on 3400 MHz Winter 2021
    • Combine two Toshiba amplifiers for 100w on 3400 MHz. 2021
    • Test New 25-35w 10-GHz PA. Winter 2021
    • Install 1.8m offset feed dish for 10-GHz EME Summer 2021
    • Install permanent CW beacon for 10 GHz (1 watt) Summer 2021
    • Construct two 12w 10-GHz PA's
    • Construct DEMI 10-GHz LNA
    • Assemble 10-GHz Loaner station
    • Assemble 3400-MHz Loaner station
