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, 30, 20, 17, 15, 12, 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 2018:

    • 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.
    • Purchased a 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.
    • The 2m-EME station running 1400w is usable for both tropo and meteor scatter.
    • A 45-element 1296 loop-yagi and an 33-element 900 MHz loop-yagi have been mounted on tower#1 and are rotatable in azimuth and elevation.
    • 50-foot tower#2 supports a 3-element triband HF yagi, 11-element 432-MHz yagi, and two 11-element 222-MHz yagis
    • By use of a Drake MN-2000 antenna tuner the triband yagi is usable on 20m/17m/15m/12m/10m.
    • A 80m-160m-600m Inverted-L antenna is strung between two towers. Reinstalled Sept, 2017
    • A 80/40m inverted-V dipole installed on a 50-foot HF tower attached to the east end of the house.
    • A 6-element KLM yagi removed for tower raising
    • New LFA2 WOS antenna to be installed on a 40-foot tower for 6m-eme/ms using 50-MHz Harris Platinum 1000w Amplifier
    • A 16-foot (4.9m) dish is used for 1296 & 3400 EME or 1420 MHz-RA.
    • I have a portable-rover station for use on 10,368 MHz.
    • New Ford F250 4x4 diesel crew cab pickup July 26, with new Alinco DR-735T 2m/70cm 50w mobile radio.
    Future Plans:

    • Install new synth boards and modify gen-coverage filter in K3 Completed Nov. 2, 2017
    • Raise 6m tower to 40-foot Completed August 4, 2017
    • Assemble new M2 440-18 UHF yagi and install on 2m eme array center Completed Feb. 9, 2018
    • Build two LFA2 6m yagis May, 2018
    • Install new 1296 600 watt LDMOS amplifier and 50v PS at the dish. 2018
    • Modify Toshiba amplifiers for 50w on 3400 MHz 2018
    • Combine two Toshiba amplifiers for 100w on 3400 MHz. 2018
    • Construct 1200w LDMOS 2m linear amplifier to replace 8877 PA 2018
    • Install permanent CW beacon for 10 GHz (1 watt)
    • Construct new 30m dipole to be installed as a sloping dipole from the HF tower.
    • Build 2.5w DEMI 10-GHz amplifier Completed April 1, 2017
    • Construct DEMI 10-GHz LNA 2018
    • Assemble new tripod with az-el mount for mw dish 2018
    • Construct two 12w 10-GHz PA's
    • Build two stations (each) for 3496 and 24,192 MHz one each to be a loaner for those bands.
