A $25 upgrade for the Elecraft KX2

Many of you know I’m quite a fan of the Elecraft KX2. I take this little transceiver along almost any time I travel. Not only is it a full-featured ham radio transceiver, but it’s also an exceptional shortwave broadcast receiver.

The KX2 is a quality US-built rig (like all of Elecraft’s gear) but I’ve never been a fan of its plastic encoder knob. It lacks a finger dimple and feels cheap compared to the rest of the radio. Don’t get me wrong: the stock encoder knob gets the job done, but it’s not nearly as nice as the one on the slightly larger Elecraft KX3.

Comparing the Elecraft KX3 (top) and KX2 (bottom) at Elecraft’s Dayton Hamvention booth.

Two weeks ago, I ran into another Elecraft KX2 owner and happened to notice that his KX2 had a solid aluminium encoder knob with a finger dimple. Turns out, he purchased the knob from a ham radio operator (W1JH) in Maine who manufactures and sells this knob on eBay.

The price was $24.95 US shipped. I didn’t hesitate to place an order.

You might think $24.95 is a lot to pay for such a small item, but third party Elecraft vendors tend to charge much more for comparable items. I’ve also considered adding a heatsink to my KX3, for example, but those can total upwards of $100!

My new encoder knob arrived in only a couple of days via the USPS–installing it was a breeze.

It took me all of thirty seconds to pull the plastic knob off of the KX2 and replace it with the new aluminium one. The seller even includes an Allen wrench to secure the new knob.

The new knob is slightly larger in outer diameter, but fits the KX2 like a glove. The slightly larger size makes the finger dimple a practical addition for smooth band-scanning.

If you own an Elecraft KX2 (or the Elecraft KX1) I highly recommend this simple encoder/VFO knob upgrade!

The Ham Station is closing shop

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who notes that Indiana-based amateur radio retailer The Ham Station is closing for business. A Ham Station staff member has also confirmed this.

Dave notes that there are some bargains still in their inventory.

Thanks for the tip, Dave!

A photo tour of the 2018 Greenwood, SC hamfest

Last week, my buddy Vlado (N3CZ) informed me about a small hamfest in Greenwood, SC–I had never attended, but had heard positive comments about it.

I believe Vlado was somewhat on the fence about going, but once I expressed a strong interest in selling some gear, he did too so it quickly became a plan!

Greenwood, South Carolina, is about a 2.5 hour one-way drive from my home. Vendors were encouraged to arrive around 7:00 to set up (general public admission was at 9:00), so Vlado and I hit the road by 4:30 AM!

Notice the lack of traffic on the interstate at 4:30 AM!

We arrived as the doors opened and purchased a total of three tables to sell our gear. My goods took up most of one table and Vlado packed the other two with his gear!

By general admission time, less than half of the vendor tables were occupied, which did worry me. However, overall foot traffic wasn’t bad at all! This vendor was certainly pleased.

I sold at least 80% of the items I brought with me, no doubt due to my generous and agressive pricing scheme (i.e. nearly giving things away–!). Vlado sold some large items, too.

In the end, I didn’t purchase a single item at the hamfest. I was in selling mode, not buying mode, at this hamfest as I’ve been making an effort to downsize some of my collection and use the money to offset the costs of travel this year. With that said, I would have snagged a classic portable had one appeared.

This BC-317 is just asking to be taken home!

Mind you, I was very tempted by two BC-317 receivers being sold together for an asking price of $60, but I resisted as the whole idea of “thinning the herd” is to make room in my small radio shack.

I find that small hamfests like Greenwood actually have better vintage radio pricing than the larger ‘fests.

Though the hamfest was modest in size, there were quite a few quality offerings among the vendors. I was very impressed with the number of transceivers–indeed, a new ham would have had a selection of affordable benchmark 90s era rigs to choose from!

Click on the thumbnails below to enlarge or comment on the photos. Most of the photos were taken prior to the doors opening but I did my best to capture price tag information if available:

Do I plan to revisit Greenwood next year? You bet!

Ed spots a Heathkit HW-101 in The Royal Tenennbaums

Many thanks to SWLing Post contributor, Ed, who writes:

I was in my corner bar last night in Philadelphia where “The Royal Tenennbaums” (2001) was playing on the projection screen. I wasn’t really watching it, but a scene showing a Heathkit HW-101 HF transceiver suddenly caught my eye. When I told my my drinking buddy, Richard, “That’s a Heathkit HW-101!” He called me a hopeless geek.

I’m not sure what tuner is on the shelf below it, but maybe a SWLing blog reader can identify it.

Great job spotting the HW-101, Ed!

Ed actually sent this tip to me several months ago, but it got buried in my drafts folder–sorry about that!

AM Radio: Ivan compiles 2017 solar eclipse logs

Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who writes:

I never got a chance to summarize my results of the AM scans I did during the 2017 total eclipse.

I used an SDR and a 40 foot end-fed antenna located in a park near the Nashville, TN airport.

On the plus side I did notice a spike of AM signals and amateur radio signals especially on 40 meters. On the negative side, my AM scans were adversely affected by the nearby powerhouse WSM transmitter on 650 kHz.

I’ve attached my results in a spreadsheet [embedded] below.

Fantastic, Ivan! Thank you for taking the time to go through your recordings and make these notes. No doubt, this log took a few hours to compile. I’ve yet to go through my eclipse spectrum recordings–!

Again, thanks for sharing!
