It was the Fort Tuthill 80, known also as the Tut80. It's a nice little rig. I modified mine for varactor tuning with a 10-turn pot (suggested by Cam N6GA) and a KD1JV Digital Dial, as well as modding

Kirk Wow, you've really done well.? My annual forays on 160 can be counted on one hand.? I'm not much of a contester and I don't chase various awards.....but I've found the Stew Perry event much to

@ KI4IO:? Yes, agree 100% that on 160, it's all about the antenna. But I think your particular inverted-L is a bit higher up in the ranks than you might think. In 2017/2018, when the ionosphere was

Howard, Though the thought of building an "NC160A" would be poo-pooed in some quarters, because I needed an excuse to warm up my iron, I purchased a 160m 1Watter from Diz, and it resulted in a nice

The price of admission for 160 is an efficient antenna.? I'm probably at the low end with a 165' inverted-L up 75' with 47 mixed length radials from 15 to 70'.? I use a K2 at 5 Watts. I like the

As AA7FO mentioned this matter, here is what I can share. On 160m I have had several CW QSOs with folk operating simple tube transmitters at 5 to 10 watts. ?So it’s definitely viable during the

In response to AF7KR's question: "Speaking of boards. ?What is going to be the economics now of getting PCBWay or other boards from China? " Here's a link to JLCPCB's FAQ about tariffs:

Chuck I had a similar experience to your fake FET's except mine were fake BF245A's. I got a refund by sending a picture of my component tester's BJT display. The generic NPN's that they had sent seem

Delayed in getting to build second ADC xcvr prototype because a package of J310s has gone across the country and back for more than a week and having trouble getting to me.? Hopefully by Monday.?

I quick look at the AE marketplace reveals ample supplies of 4MHz crystals.? That with a 2-to-2.2MHz VFO would tune it down to the 160M band.? There is also a 4.433MHz HC-49s crystal offer, but 3x

Howard you have a fantastic idea. Avoid an IF that is a multiple of 1.8. Sounds pretty easy. While TR signal should work I wonder if it might carry transmit RF leakage? ?You may have to experiment

Good morning, all.? I'm thinking about a 160M build using one of my leftover NC40A boards. I actually only need the receive side but with a bit more work can eventually get a complete transceiver.?

Also if you notice I widened the sweep this time to include the 4th harmonic which shows up about the same level as the 2nd harmonic. I imagine the other filters show the same for the 4th harmonic.

I built the 30M W5USJ LPF from the chart, next. You'll notice on the chart that the input and output impedances for this filter are close to 50 ohms with little differences. My tests showed the

Hi, A while back, I noticed the familiar double-pi filter circuit that’s often used at output of transmitters. One day, I did some calculations and realized the connection between the values of L

Hi Goody, I built the W5USJ 80M LPF from the chart just now and tested it; I used T37-2 toroids, 22 and 23 turns, inductances set with the DE-5000 LCR meter, silver mica caps except polystyrene for

Hi Steve, Thank you for the information! I was wondering how one designed these as I wasn't finding any direct design tools online. The chart will be enough to get me started; I'll build it and do

Wow that is an amazing difference!? Next time I need one I will try to use this.? Sounds like the design is a bit more involved though. Thanks!

8 have never seen the videos and would appreciate if they were available again! Thanks ?
