This is a photo of the Knight Kit "Span Master" SuperRegenerative Receiver kindly supplied by Richard
Post - KB8TAD. |
The schematic diagram for my first 6L6 (8 watt ) ham transmitter is shown below.
The circuit was found in "The Radio Amateur's Handbook" by
A. Frederick Collins 10th Ed. 1961

Knight, Span Master | Gone. Don't know what I did with it. I've seen this two tube super regen. auction for a quite a bit on Ebay. This was probably the first for many hams and SWLs. |
Old 40s RCA multiband, pulled from a console. | I made my first ham contact using this receiver. I eventually pitched it. |
Hallicrafters, SX-110 | I remember seeing this attractive receiver in a store window on "radio row" in NYC. My father gave it to me for Christmas and I used it for a few years. It seemed to drift indefinitely. I would have my right hand on my CW key and my left on the tuning knob so I could keep following the received signal as it continued to drift. I wasn't curious enough to see how far it would go before stabilizing. Gave it to Father Zachery at my church in the late 60s. Most tube receivers I had were not fully stable. Once, solid state, digital receivers came along, drift was no longer an issue. |
Hammurlund, SP-200 | I rebuilt circuitry. Gave it to my cousin, Mitch. |
Hallicrafters SX-43 | Used it while in USAF. Don't remember what happened to it. I loved the half-moon dial and S-Meter. |
Hammurlund, HQ-110 | Used it while in USAF, Sold it! |
Hallicrafters, SX-101A | Used it while in USAF, Sold it! |
Ten-Tec OMNI-D Transceiver | Still have it. Great little box! I've owned this longer than any other piece of equipment -- about 33 years. |
Clegg, FM-28 2 Meter Transceiver. | Bought if trom my late friend Peter Floro, WA2FCF SK. Used it for both mobile and VHF Packet. The transmitter part quit. Trashed it. |
Radio Shack DX-300, digital. | Gave it to my nephew, Timothy. |
Hammurlund, SP-600 | Given to me by my friend, Rich. Later, gave it to my friend Bruce. |
JRC, NRD-525 | Still have it. Wrote DOS GUI shareware program to control it. Audio is OK for communications,
but the distortion (slightly clipped - raspy) makes it undesirable if you want to record air checks from AM broadcast
stations. Next to my reclining chair. Use it to listen to WHLI AM in Long Island and WBCQ The Planet. I suspect I will own this one till the day I die or it dies. |
ICOM, R7000 with NTSC Television adapter |
Still have it. Use it for FM broadcast listening, but, occasionally, listen to weather, police and 2 meter QSOs. The NTSC television adapter was really cool before the HD mandate. |
Sony SW-100 | While it worked, it was terrific. I could take it anywhere and it was handy when I was testing the audio on my transmitter. I could put the receiver in my pocket and walk around with the earphones one while messing around with the AM transmitters in my garage. After owning it for 3 years, the '0' button, the mode and some other important buttons quit working after three years. I opened it up figuring I had nothing to lose, but saw no way to get the buttons working, so I pitched it. It was the size of a cigarette pack and I used to take it on trips. |
Two Hallicrafters SX-28 | Purchased in 1998. Beautiful receivers with very very fine fidelity. I dare say, that on
top of being general coverage receivers, the SX-28 is the best sounding AM receiver I ever heard! Sold them both at Sussex County Hamfest in 2008 for about the same price I purchased them for. |
NC-105 | Purchased at hamfest in 1999. Cute little tube receiver for tuning around. Good condition. Sold it again at hamfest for less money. |
Drake R8B. |
I purchased the Drake R8B late in 1999. I especially like the filter selection, the variable
passband and the fine audio of this receiver. The variable passband is especially nice for receiving PSK31. I think it is a terrific receiver. I predict I will own this also till the day I die. NOPE! Gave it to my nephew-in-law Christopher Burrell KE0QVK on Feb 15, 2020 via USPS, to be received on Feb 18! There are only two things I don't like about the look and feel of the receiver. 1) The tuning does not have a flywheel weight so you cannot spin the dial. 2) When the receiver is off and you have not set the clock, it displays the word "PWRLOSSL" on the front. I have no interest in using the clock part, so I'd rather either see nothing or have a way of turning this warning message off. |
Grundig G6 Aviator | Not very good, to put it politely. Poor dynamic range. Overloads easily. Bought it for power outage emergencies. |
FLEX-3000 Software Defined Receiver (SDR) |
Purchased in 2012 |
FLEX-6500 SDR | Purchased in April 23, 2014 Best transceiver I ever had. The TX audio is so good on this
transceiver, that it scares some NON-SDR hams. My Grainy voice is so faithfully reproduced that it is mistaken for distortion. |
Ten-Tec OMNI V | From estate of my late friend, Peter Floro, WA2FCF SK Never used this rig. |
ICOM IC-746 PRO | From estate of my late friend, Peter Floro, WA2FCF SK Never used this rig. Gave it to my nephew-in-law, Christopher Burrell, KE0QVK. |

At Hopatcong, NJ. |
The only time I had beam antennas was the last 2 or 3 years at Hopatcong circa 1982-1983. A TA-33 and 6 meter beam was mounted on a tripod on the roof. I moved to Hamilton Square, stayed there for about seven years, got remarried, moved to Cranford for a yrar, then here in Middletown. In all places, it was stored away in pieces when I finally gave it away to the guy that bought my BTA 500R. |

My rig in various times and places in my life. I've never won any contests nor collected tons of QSL's, but
I sure had fun setting up different rigs in different places.
The first picture is of me when I was 15 years old. That was over 30 years ago! I lived in River Edge, NJ at the
time.
The most exciting part of ham radio to me was building my 813 rig. The top right, B&W picture shows the front
and back of the rig. I modeled it after construction I had observed on broadcast transmitters. It consisted of
two standard 19" racks. The right rack contained the power supplies for the modulator and final, the audio
driver to the modulator and the modulator itself. I had a special 220 Volt line for my transmitter. The plate transformer
was about 1 cubic ft in volume. I purchased it from Barry Electronics in NY. The rectification consisted of 2 872A
mercury vapor for the final and 2, 866A mercury vapor for the modulator. The left rack consisted of the RF driver,
an Eico 720 transmitter, and the final which consisted of a pair of 813 tubes using a link coupled tank circuit.
The tank coil was 1/4" copper tubing.
The bottom photo (taken with my new Olympus D-600L digital camera) is my current radio/computer room. Equipment
visible consists of Johnson Valiant purchased at a hamfest in (7/96). It works fine on CW, I haven't checked out
the AM, yet; NRD525 (100KHZ - 34MHZ), Ten-Tec CW/SSB Transceiver 21" computer monitor, dual pentium-133 w/64MB
RAM with Windows-NT 3.51 (used for graphics and animation work) and 486/100-DX4 w/32 MB RAM with Windows-95 (used
for everything else). Antenna is 20 meter dipole! I always liked dipoles. They're inexpensive, easy to put up,
you can hide them easy so your neighbors don't even know your a ham and they work pretty well when installed correctly.
I have a TA-33 beam which has been in pieces since 1984 which is better than a dipole, but it'll take a bit more
to put it back up again and this town doesn't seem to like towers.
