Merchants

Online merchants

Many merchant reviews can be found at the eHam Company Reviews forum from other HAM operators sharing their experiences.

club equipment

Some of the equipment I was able to operate by the kind provision of our local radio club.

  • Kenwood TS-450S

Kenwoodts450s.jpg

Drake TR-7

later model with a serial number 89xx

Software Defined Radio (SDR)

  • SoftRock RXTX 30-20-17 meter SDR transceiver QRP
  • SoftRock RXTX 15-12-10 meter SDR transceiver QRP

GMSK(digital)

Gaussian Minimum Shift Keying or Gaussian filtered Minimum Shift Keying, GMSK, the form of modulation with no phase discontinuities used to provide data transmission with efficient spectrum usage.

  • Icom ID-800H Digital Dual Band Mobile Transceiver with D-Star

Purchase Consideration

Equipment I do not own but have been researching and in consideration for purchasing. If I make a purchase I will use and follow up with a review of the product. We like to do product reviews here.

Test Equipment

I like the roller inductor style operation of antenna tuners for HF, however, I don't need a model that handles 1.21 gigawatts! Been looking around to see if there is a less expensive version of these.

Also noticed MFJ gets a lot of negative reviews. Our club uses MFJ tuners, they seem to work.

  • MFJ 969 Antenna Tuner - has roller inductor. $200 new. 6 thru 160 Meter HF Bands (1.7Mhz To 55Mhz). 300 Watts.
  • MFJ-986 Antenna Tuner - roller inductor, high wattage. $330 new. 1.8 - 30 MHz, 3000 Watts

Transceivers

ICOM IC-736 - 160 to 6 meter

Expand your horizons to 6 meters with the Icom IC-736. It also covers 30, 17 and 12 meters. This all band transceiver features a 500 kHz to 30 MHz general coverage receiver. The 736 has a built-in HF and 6 meter antenna tuner. Enjoy 5 to 100 watts full duty RF power input in SSB/CW/FM (40W AM) modes, even on 6 meters. For CW operators full and semi break-in is supported.

Icomic736xceiver.gif

160-6 Meter Transceiver w/built-in tuner . Maybe in production? Absence of receive coverage from 30MHz to 45MHz. 6-meter is technically (50-54 MHz) so the gap exists in non Ham freqs. The lack of receive between 30MHz and 45MHz and the CW tuning arrangement are the most notable disadvantages.

Information on Universal-Radio Discontinued HF Transceivers including band coverage.

Icom IC-718 HF - A Modern Full Mode HF Transceiver

This one is still in production. It's straightforward easy to operate modern HF rig.

0.03-29.999999 MHz* general coverage receive capability. *Guaranteed range: 0.5-29.999999 MHz

Yaesu FT 980

The Yaesu FT-980 is a deluxe HF transceiver covering 160 to 10 meters amateur bands in SSB, CW, FM and AM Modes. This radio features two independent receiver front ends. One is for general coverage receive from 150 kHz to 29.99999 MHz and the other for the amateur bands only. Seven JFETs are employed to provide extraordinary dynamic range. Ten VCOs are used over the local signal range to secure a low carrier-to-noise ratio. A three-step attenuator is provided to deal with the very strong signals. The triple conversion design incorporates four cascaded stages of IF filtering for all modes. Twelve memory channels are available. Using push-pull MRF422 final transistors, rated at 280 watts each, the transmitter coasts along at 100 watts output. Full break-in QSK is provided for CW operation.

I'm not a fan of push button and menus. I like independent pots.

TYT TH-9800 Quad Band

TRANSCEIVER, 29/50/2M/70CM, CROSS BAND, 50 WATT - Yeah one of them there CHINA knockoffs. However, for the price this little guy does a lot. I've read quality many vary widely as is the case with this Chinese stuff. I am looking at one now that has been fully tested at a shop in the United States. They are also being sold on Amazon.com

Clear Channel Ranger AR-3500

I own a 100w model Clear Channel AR-3500. They were available in a lower 30w version (I think) and a more powerful 100w version. The 100w version has massive heatsink fins on the rear with the longest two on both ends. It is easy to tell them apart. I have been thinking about selling it as I no longer do much on 10-meter. I've been watching prices to get an idea of what I would want for mine if I decide to sell it.

Coaxial Cable Index

RG-59 or RG-6 should not be used for ham (75ohm TV)

RG-58 (CB cable) has a high loss factor in VHF and UHF frequencies, so it really only is useful in runs less than 50 feet for frequencies above 100 MHz, and 20 feet for frequencies above 400 MHz.

RG-8U is great for 50-75 foot runs in the VHF/UHF range.

UR67 or RG213 for 70cm.

LMR-400, Belden 9913 for 100 feet + in 70cm amateur radio, or GMRS.

RG8, RG8X, RG58U

RG58U

  • more flexible
  • lower cost
  • good for short runs with mobile installations

RG8

  • less loss on long runs 50ft - 100ft
  • thicker and less flexible

RG8X (mini foam)

  • smaller than RG8 with less loss than RG58U
  • still not as good as RG8

Microreader

decodes cw and displays text. listen to cw without knowing Morris code.

  • ERA Microreader MKII CW Decoder - a stand alone solid state cw decoder circa 1980s that works well.
