Weston Model 425A RF Ammeter
$80.00
This is a thermocouple type RF ammeter which includes a 1250 watt power scale marking as well. It's in good physical condition, but UNTESTED. However, the pointer is not stuck, nor does it swing wildly, so it seems okay. The front glass is in good condition but is a little loose in the frame of the meter.
This meter would look spendid in your high power homebrew MW or HF transmitter or amplifier.
Price does not include shipping. I ship only to the USA and maybe Canada.
AEA Morse Machine MM-3
$130.00
AEA Morse Machine MM-3
This is the classic CW memory keyer, trainer, and beacon from Advanced Electronic Applications. Check the pictures for all the software and interface options.
A notable feature of the trainer mode is the QSO simulator where “stations” will call CQ or respond to your call and engage in a basic amateur CW exchange. Pretty advanced for 1989 microprocessor tech!
This unit is in very good condition inside and out. Not surprisingly, the internal battery for maintaining the settings while powered off had gone flat after 30 years. I removed the battery, which was soldered to the board, and replaced it with a coin cell holder so future battery changes can be done easily. See the internal photo on the lower right for this mod.
The 9 to 16 V power supply and paddles are NOT included. Shipping $10 to US addresses only.
Broadcast Engineering & Maintenance Handbook
$30.00
A somewhat hard to find vintage TAB book by Patrick Finnegan. I wouldn’t call it a manual for the modern broadcast plant, but if you’re looking for a copy then here one is. Very Good condition.
shipping by “media mail” price TBD.
Rockmite 40
$50.00
This is an original Small Wonder Labs 40 meter Rockmite qrp cw transceiver. This is a “stock” radio with 2N2222A final. Included is the American Morse CNC machined “Mitybox” enclosure in blue anodized aluminum.
The Rockmite is crystal controlled on 7040 khz. It seems the QRP calling frequency has changed since when I first built this radio, so I will throw in a pair of 7030 khz crystals if you feel like removing the board from the Mitybox and changing them out.
$10 shipping to US addresses.
Realistic PRO-4
$60.00
The 1974 Radio Shack catalog introduces the PRO-4 as the first handheld or pocket portable scanning VHF receiver.
View Details Realistic PRO-4
That initial version required TWO 9v batteries for operation! This unit, shown in the 1975 catalog, needs only a single 9v battery for power with convenient space for a “spare battery.”
The “easy-access” crystal compartment has 2 crystals installed, 156.80 MHz and 155.55 MHz on channels 1 and 2, respectively.
The unit is in good condition as shown in the photos. Check the “breakthrough” features of this radio in the catalog snippet from radioshackcatalogs.com.
Important note: This scanner listed is for the Radio Shack or antique scanner collector. If you are looking for a programmable scanner with hundreds of channels and multiple frequency bands, then this is not the radio for you.
$10 shipping to U.S. addresses
Inovonics 222 Processor
$280.00
Inovonics 222 AM Preemphasis/Low Pass Audio Processor.
Clean and in very good condition overall. One spot on the front panel lost some paint when I removed the metallic tamper decal which a previous owner had over the "Output Level" and "Pos. Peaks" control ports.
Price does not include shipping.
Behringer MX 802A
$45.00
Behringer MX 802A "Eurorack" 8 channel mixer with power supply.
Powers on but otherwise untested. Price does not include shipping.

Field Report July 2021
Field Report July 2021
The family vacation in July provided the opportunity for some portable QRP field operation. This outing made for a lot of "firsts."
First time getting on HF in many years. First CW qso in even more years. First time putting my FT-818 on the air. First time participating in POTA and SOTA.
Originally I had hoped to activate Calaveras Big Trees State Park K-1134 for POTA. But with all the other firsts going on and the effort invested in learning how to setup and operate the portable station, tearing it all down to setup it up again with less supporting infrastructure was more than I was in the mood for. So I just left the EFHW where it was, strung up between the deck and the trees and was content to operate from the comfort of the cabin.
Overall I made five QSOs, which may not sound like much, but I consider it an unqualified success, given I haven't even been active on HF for ages.
Here is the log:

Radio Preparedness
Radio Preparedness
In response to recent questions, I have written a short missive on the subject of radio in the role of preparedness.

Usedradiomall Is Back!
Usedradiomall Is Back!
After a several year hiatus I've brought usedradiomall.com back to the interwebs. It's different this time!
Yes, I'm still using the "Classified Ad" presentation format, however, gone is the scheme where the site was simply a curated list of ebay partner network linked items. The ebay partner network thing made a little money, but less and less as ebay changed the program to payout less. The money was not reliable, and worse, the "curated list" of affiliate links didn't really add anything of value to the radio community.
The new Usedradiomall is simply a place for me to list my excess radio equipment for sale directly to the public. Selling on ebay is a hassle and expensive, so I just decided to list this stuff myself.
If the website proves useful then I intend to invite other radio enthusiasts I know to list their excess radio "stuff" if they want. At the moment I don't have any plans to open it to the general public. Usedradiomall is not a…
