Re: A simple frequency spotting modification kit for legacy Bayou Jumpers.

 

I would like to report how I frequency spot with my original BJ. I have used the methods described in the instructions (putting the crystal across the antenna input and listening for the heterodyne with the key down in RX). Listening to the heterodyne with the key down in RX is easier than removing the antenna connection and the crystal each to time spot. The problem with my BJ is that the heterodyne whistling zones are far apart and the dead zone is wide. 
I happen to have an old Whiterook Mini-Keyer Model MK-60MB. It contains the Embedded Research chip "Tick-2". First I used it as an iambic keyer to solve the no sidetone issue and it worked well. I then decided to put it in straight key mode while using a straight key.  It also worked well. I then noticed that when I held the straight key down in the RX BJ mode I heard a very, loud heterodyne. It is not only loud but the whistling zones are close with a very small dead zone. Using a second rig and having many BJ QSOs I find that I can not only pick out my transmit frequency very accurately (both upper and lower sideband) but I can also repeat the spotting easily without removing the antenna or even adjusting my Atten or Regen. This certainly helps as my BJ has a mild drift.

I mention this not to have BJ owners buy a Tick-2 keyer (although if you have one laying around give it a try) but to perhaps figure out why it works so well and develop a simple and better frequency spotting mechanism. 

I have the original BJ and I of course did the Keyer mod with TIP42G as seen in the new BJ Rev B instruction manual appendix K

If any of the builders are interested I would be happy to make any measurements needed to find out why it works.

I wonder if most people build the filter in to the unit or use it as an external addon. That would have the advantage of being used with other rigs. I'm leaning toward building it into the rig and just adding a switch.

Its a great audio filter. 
It takes power, audio in and out to headphones. 
I built one stand alone and used a double pole double throw switch as a by pass. 
this lets you get close then narrow down on a signal.

I have the original white faced BJ which works extremely well. Nevertheless a filter would be helpful. My Hi-Per-Mite should arrive today or tomorrow. I plan on trying it as an external addition first. If that works, I have a plan for putting it in the BJ wooden suitcase. I can let you know how it goes.

Re: What Kit's would be nice for 2021

Jeff, K9JP
 

How about converting that NDB receiver into a one watt tunable transceiver for 630 meter band? The 630-meter (or 600-meter) amateur radio band is a frequency band allocated by the International Telecommunication Union (ITU) to amateur radio operators, and it ranges from 472–479 kHz,

That would help create interest in low frequency communications and antenna experimentation. For an antenna I might try making a PVC pipe rolled base coil and a short (5-8 foot) stinger.  Something I could hang in my garage and even using two of them to make a right angle dipole. Yes, efficiency will not be great, but think of the fun talking to other area hams (maybe DX the next town over) and maybe make a few new friends as well.

Re: What Kit's would be nice for 2021 (what is a NDB?)

David Wilcox
 

NDB = Non Directional Beacon like the old aircraft beacons that used to identify airports and give old time pilots a signal to follow to the airport or take reading from three or four beacons and use that to tell where they are...... they are slowly wearing out and not being replaced since GPS is much more accurate and receivers are so cheap.

Some radio enthusiasts still get a hoot listening for them in the long wave band and some even go so far as to head out in the wild open spaces (noise free places) for a listening contest on weekends.

An NDB is used by aviators and mariners for long-range navigation and are typically located on mountaintops and promontories overlooking coastlines.  They simply transmit one, two, or three Morse characters at 5 wpm over and over, on 190 KHz to 1,750 KHz, although normally NDBs in North America operate between 190 KHz and 535 KHz (some AM radios can pick up those on 530 - 535 KHz) modulated by either 400 or 1,020 Hz.  They're depicted on navigation charts (there's no such thing as an aeronautical or maritime map) by this symbol:

image.png

Therefore, their position is precisely fixed and known, and they're broadcast-only - you can't communicate with them.  However, their power levels can be as low as 25 watts, and some range up to 2 KWs.  They're favorites of DXers because, under the right conditions, they can be received much further than their intended range (but you can't receive a QSL card from them!).  

The U.S. system is being decommissioned by attrition at the least-used sites, as well as a plan to eliminate about 50 per year through 2025.  Aviators and mariners are strongly opposed to this plan, because GPS can be fragile for a variety of reasons, including lack of good coverage at higher latitudes, and others which can't be discussed at the unclassified level.

NDB is a non-directional beacon,  used for aircraft navigation. They were largely replaced by VORs in the 1960s and later mostly superceded by GPS. Nevertheless some NDBs are still operational.  Our 1975 vintage Cessna 172 has a NDB receiver in it. Just for fun I used it the last time I flew into Lincoln,  IL. The NDB on that airport is callsign AAA.  NDBs operate on frequencies below the AM broadcast band.  Normally they are heard no more than 20 miles,  but when propagation is good I've heard hams and SWLs report hearing them as much as 1000 miles away. If you are bored on a winter night tune around 300 to 400 KHZ and listen for 3 digit CW identifiers being sent at 5 WPM. Those are NDBs.
