New Product: Kev-Flex Stealth Kevlar Antenna Wire

Leave a comment

My good friend David Cripe (NMOS) has recently informed me about a new product he’s offering to the radio community via his eBay store: Kev-Flex Stealth Kevlar Antenna Wire. Kev-Flex looks like a superb option for field antennas of all stripes especially since it has an incredibly high tensile strength. It’s available in 75′ bundles, but Dave can also cut custom lengths. NM0S is also a trusted retailer in the ham radio world, so you can purchase with confidence.

Here’s the product description and link:

Kev-Flex is a unique antenna wire manufactured exclusively for NM0S Electronics. The lightweight center core of the wire is made from Kevlar fiber, giving the wire its incredible strength. The Kevlar core is wrapped with six tinned strands of 30 AWG copper. The effective surface of the wire creates an effective skin area capable of handling well over 100W.

The cable is protected from the elements by a coating of UV-resistant black polyethylene. With a total diameter of only 1/16″ (incl. insulation) and a weight of just 16 feet per ounce, the tensile strength 125 lbs allows lengthy unsupported horizontal runs. Kev-Flex is ideal for extremely long LW-antennas and Beverages and is great for balloon or kite-supported antennas. Its low weight and high break-load makes it most suitable for SOTA activations and other field operations.

The outer insulation makes the wire kink-resistant, and its slippery finish makes it ideal for stealth antennas that must be passed through trees or other obstacles without snagging.

This antenna wire is sold in 75 foot long bundles, which is enough for a 40M dipole or EFHW. Two 75 foot bundles would make a great 80M dipole. Custom lengths are available on request.

Specification

– Kevlar fiber core wrapped with six 30 AWG copper strands
– Weather-proof black polyethylene (PE) insulation, 1/16″ O.D.
– Weight: 16 feet per ounce
– Breaking-load: 125 lbs
– Velocity factor 0.97

Thank you for sharing this, Pete!

I may see about grabbing an IQ-32 to evaluate. I’m very curious how its receiver might stack up to the Elecraft KX2, the CommRadio CTX-10 and the LnR Precision LD-11. (Please note that these links lead to my other radio site, the SWLing Post.)

It doesn’t appear that the IQ-32 has an AM mode, but I would still like to see how it might handle broadcast listening on the shortwave meter bands using ECSS.

The CommRadio CTX-10 has landed

1 Comment

[Note: This is a cross post from my other radio blog, the SWLing Post.]

Yesterday, UPS delivered a much-anticipated package: the CTX-10 QRP transceiver from CommRadio.

CommRadio dispatched this loaner CTX-10 for evaluation and I’m excited to get my hands on it since it’s not everyday I get to evaluate a transceiver designed around field portability (my favorite category of gear).

Yesterday, I took a few shots of the CTX-10 as I unpacked it:

I’ll need to build a fused power cable with the supplied pigtail and also sort out an 8 conductor (Yaesu compatible) modular plug microphone. Of course, I’ll give this radio a thorough review testing it on SSB, CW and digital modes (especially FT8).

Since the CTX-10 is built on the CommRadio CR-1 and CR-1A I anticipate a capable receiver section (in other words, expectations are high). Of course, I’ll test the CTX-10’s ability as a broadcast receiver as well.

LnR Precision’s new Sideswiper produced for the Straight Key Century Club

6 Comments

Those of you who are fans of single lever paddles will be pleased to learn that LnR Precision has announced the latest key in their product line: the SKCC Sideswiper.

Here’s the description from the product page:

The SKCC Sideswiper is patterned after the Kungsimport key produced in Kunsbacka, Sweden in the 1980’s by Hakan Scard (professional operator at Gothenburg Radio, SAG) and Ben Jomkert. It is a classic very traditional Sideswiper produced for the Straight Key Century Club.

The light weight Oak fingerpiece allows for a close gap setting making it a very fast key with little chance of chattering. The heavy 2.8 pound base makes it a very stable device on your desk. No chasing this key around the desk or needing two hands to operate.

Key Features:

  • The SKCC Sideswiper base has a 4″x 3.25″ powdercoated cold rolled steel base with SKCC logo
  • The blade is highcarbon spring steel and features a Lightweight Oak Fingerpiece
  • Upper hardware is anodized aluminum with matte finish.
  • Weight is 2.8 lbs

I think this is a beautiful key–I love the simple design, heavy base and the fact they’re made by a quality key manufacturer.

The price will be $94.95 US.
Thanks for the tip, WD8RIF!

Many thanks to Pete Eaton (WB9FLW) who writes:

From the fertile mind of QRP Hall Of Fame Pete N6QW comes a new Radio Project, the Sudden QRP SSB Transceiver. If you have never Scratch Built such a Rig and would like to N6QW’s latest offering deserves close inspection.

Using only readily available (and cheap) components (and few of them) one can build a Full Blown SSB Transceiver for either 40 or 20 meters. The Radio’s Design will be featured in 2 installments of GQRP’s Sprat Magazine. The 1st being in the Fall issue (Receiver/LO) and the second part with come in the Spring 2019 issue (Transmitter).

http://n6qw.blogspot.com/2018/09/2018-year-of-ssb-transceivers_14.html

Pete is also providing extensive documentation on his Website:

http://www.n6qw.com/Sudden.html

One use for the Rig is on the Digital Modes, to that end he has design a simple Digital Adapter (which is also described on n6qw.com). One possibility is for a dedicated FT8 Transceiver!

Even if you do not intend to build the Rig take a moment to check out his Web Page. There you will find a wealth of information on designing and building such Transceivers.

The uBITX Transceiver: Pricing and more details

5 Comments

Many thanks to Pete Eaton (WB9FLW) who shares pricing and additional information about the uBITX general coverage QRP transceiver:

Here are the details, if purchased before Christmas $109 delivered!

http://www.hfsignals.com/

From uBITX creator, Ashhar Farhan:

1. The ubitx is now available for sale, for $109 dollars (includes the shipping), but only until Christmas. *After Christmas, the price will increase to $129 dollars. for this initial batch, a few ham volunteers and I pitched in to sort the crystals, test the coils, tune-up and box these initial kits, we won’t be able to do that any more. we will have to hire more people (which is not a bad thing) and get them to do it.

2. The ubitx is on sale at hfsignals.com, not hfsigs.com. it is easier to remember. we will soon point hfsigs.com to the new website as well. The new site is in wordpress, that means that we can have volunteers writing and updating it rather than waiting for me to hand code the content in html and vi editor.

3. We need help with proof reading the web content.* If you find any typos, please mail me on [email protected] address (not the bitx20 list),

These apart, the early buyers must be aware that they are beta users of sorts, the firmware will sure get updated. i hope there won’t be any revisions of the PCB.

Pete adds:

Just as an aside the original price of the Heathkit HW-8 was $139.95 (in 1970 dollars) and it became a QRP Classic. The uBITX may become  one as well and like the HW-8 there will be (and already are) all sorts of mods/additions one will be able to do. The uBITX is 10 dollars cheaper (after 12/25) works 80-10 M, does SSB in addition to CW, and is a Superhet to boot!

Farhan your hit this one out of the Ballpark!

Very cool, Pete!  I am very tempted to purchase the uBITX transceiver before Christmas and have it delivered via DHL service.  The only thing holding me back is simply the amount of projects I have on my table at the moment! $109 is an incredibly low price for a full-fledged QRP transceiver!

I’m absolutely amazed that it is also has a general coverage receiver.  Perhaps the uBITX could serve the SWL as well as the ham radio operator?  I suppose we shall soon find out!

The new CommRadio CTX-10 QRP general coverage transceiver

Leave a comment

commradioctx-10

[Originally poublished on the SWLing Post.]

Many thanks to Fred Osterman and Dave Zantow for sharing information about the new CommRadio CTX-10 transciever.  Here is the description from Universal Radio’s catalog:

AeroStream Communications near Golden, Colorado entered the hobby radio market in 2013 with their revolutionary CommRadio CR-1 and follow up CR-1a SDR receivers. The success of these innovative radios left many asking for a transceiver of similar size and capability.

The answer is the just announced CTX-10.

The CommRadio CTX-10 blends high performance, internal SDR technology, high efficiency circuit design, compact size and simple operation. This multi-mission QRP radio is ideal for field use and emergency operations. Transmitter covers 160-10 meter amateur bands with output power adjustable from 1 to 10 watts. The new design uses ruggedized land mobile power amps in push-pull. Every aspect of the radio design is optimized for low power consumption.

The efficient and sharp OLED display is readable in low or high lighting conditions. The radio has three built-in #18650 3.7V 2600 mAh Li-ion batteries providing 28.8 watt-hours of operation. A built-in intelligent charger provides seamless power management.

The general coverage receiver section uses multiple preselectors for optimized reception from 200 kHz to 30 MHz. An integrated CW reader and antenna tuner enhances portability. The premium tuning knob optical encoder is rated at a million revolutions.

Entire enclosure is aluminum with metal knobs and front panel. External connections are through-hole mounted for durability. Includes USB cable, DC power cord and manual. DC power requirements: receive 1.5 W, transmit 20 W. This quality device is robustly built in Colorado, U.S.A.

I’m really looking forward to reviewing the CTX-10. If the CR-1 and CR-1a are indicators, this could be a very well-built unit with a top-notch receiver!
