1960s Motorola Model T1204A with Lawson Clock, Vintage Remote Ham Radio Unit

1960s Motorola Model T1204A with Lawson Clock, Vintage Remote Ham Radio Unit

This unit was owned by a Ham Radio operator, his ID code was KGR 428. This is some sort of Ham Radio outfit, but I do not know what it is really named. The sticker on the back has a date from 1966. I have this information from a radio engineer that looked at my photos. Upon observation of your photos, the unit you are showing is a remote control for a base station located off premises. If you look at the rear photo, you will see terminals for the remote telephone line used during those days to connect the control unit to the transmitter and receiver. There is no coaxial cable connector anywhere on the chassis.. The only electronics inside is a microphone preemplifier to develop the audio level to drive the telephone line, as well as a small speaker amplifier There is no radio receiver or transmitter inside the unit. I plugged it in and the clock in upper corner works. When I look inside I see one tube light is lit red near it’s base. I don’t know how to test it further and I cannot say if it works. Very clean for 56 years old, looks great. It is a heavy item, weighs 27 pounds all by itself. This item is in the category “Consumer Electronics\Radio Communication\Ham, Amateur Radio\Ham Radio Transceivers”. The seller is “lbese” and is located in this country: US. This item can be shipped to United States.

V0.6 RTC MOD CLOCK 10W 0.5-30M RS-929 QRP SDR Transceiver CW AM SSB 300Hz-10Khz

This item will be avilable after 23th as China Lunar new year is coming, Limited quantity available, we will send accroding to the order time, FIRST COME, FIRST SERVED. New verison Built-in battery RS-929. Output POWER: <=10W(44dbm) Transmit: 160,80,60,40,30,20,17,15,12 and 10 meter amateur bands. Receive: 1-30 MHz nominal including general coverage, 0.8-32 MHz at reduced specifications. Receiver sensitivity for 10dB S/N, CCITT filtering, taken at 28.3 MHz: Frequency Translation enabled: - Better than -111 dBm (0.6uV) in a 2.3 kHz bandwidth - Better than -126 dBm (0.11uV) in a 300 Hz bandwidth - Frequency Translation Disabled: - Better than -108 dBm (0.89uV) in a 2.3 kHz bandwidth - Better than -120 dBm (0.22uV) in a 300 Hz bandwidth - The above specifications are for a receiver on which the published sensitivity modifications are performed. Frequency coverage: - Transmit: 160,80,60,40,30,20,17,15,12 and 10 meter amateur bands. Receive: 1-30 MHz nominal including general coverage, 0.8-32 MHz at reduced specifications. Note that the ability of the Si570 to tune the radio below 2.5 MHz is not guaranteed in its specifications, but most units have enough range to tune just below 1.8 Mhz. Maybe there are some small gaps where LO does not work- if it works, it works fine. Indicator is the color of the frequency digits: White: fully working Yellow: mostly working, maybe there are some small gaps Red: not working Spectral Display Modes: - Spectrum Scope: This is a spectrum analyzer with the vertical divisions representing userdefinable amplitude variations of 5,7.5,10,15, 20,1 S-Unit (6dB), 2 S-Units (12dB) or 3 S-Units. The baseline ("reference level") of the analyzer is automatically adjusted so that the signals within the displayed passband best-fit the dynamic range selected by the userselected dB/division. A graticule along the bottom of the display indicates the approximate frequency of the signal being displayed over a width of +/- 24 kHz. Waterfall Display: As with the spectrum scope, the frequency is displayed along the "x" axis but the signal strength is implied by the displayed color. The newest signals are displayed along the bottom of the screen, but as new readings arrive, the representations of the older signals are shifted upwards giving an ephemeral time record of recent activity on nearby frequencies. There are several options for color "palettes" that range from simple grayscale to "cold-hot" to "rainbow" to represent weak to strong signals. There is also a "Magnify" mode for both the Spectrum Scope and Waterfall Display mode that provides 2x magnification, reducing the visible spectral width to just +/- 12 kHz 24 kHz total. Transmitter power output: <=10 Watts, typical, linear. Modifications may be made to increase this: Follow the discussions in the Yahoo group. Frequency stability: +/- 30 Hz at 14 MHz over the range of 10 to 35 C, ambient with the transceiver in the case or better with the TCXO active. It can be much better than this. FM sensitivity for 12 dB SINAD, CCITT filtering: 7.2 kHz BW filter: -103.7 dBm (1.46uV) with 1 kHz tone at +/-1.5 kHz 10 kHz BW filter: -102.1 dBm (1.75uV) with 1 kHz tone at +/-1.5 kHz 10 kHz BW filter: -104.0 dBm (1.41uV) with 1 kHz tone at +/- 3kHz 12 kHz BW filter: -102.7 dBm (1.63uV) with 1 kHz tone at +/- 3kHz 15 kHz BW filter: -99dBm dBm (2.50uV) with 1 kHz tone at +/- 3 kHz CW mode receive/transmit and frequency display details: Nine modes of CW display/shifting are available to emulate the various makes of radios and suit the user's taste, ranging from no shifting, display-only shifting, display and LO shifting and manual or automatic LSB/USB shifting. In CW mode "CW-L" or "CW-U" , is displayed depending on whether LSB or USB is being used for reception. CW Speed range: 5-48 WPM. Available audio filter bandwidths in this firmware version: 300 Hz, 500 Hz, 1.8 kHz, 2.3 kHz, 3.6 kHz, with a "wide" filter of 5,6,7.5 or 10 kHz being selectable in all modes except FM, where the filtering is done prior to demodulation as noted above. All filters are softwaredefined and additional bandwidths could be made available. Filters can be used as BPF or as LPF selectable in main menu. DSP Filtering Capability: Noise reduction and Automatic Notch Filter with adjustable parameters. Notch filtering is disabled in CW mode for (obvious reasons) or when using a "wide" receive bandwidth. Devel-branch: Because NR activation leads to instability of mcHF it is disabled by default. If you want to use it (and risk instabilities in various scenarios) you can activate NR in config menu "last item". Setting will NOT BE STORED and must be activated after every powering on. When NR issues are fixed and NR will be improved this function will be obsolete. S-Meter calibration: - "Industry Standard" IARU Region 1, Technical recommendation R. Units above S-9 are in dB units, as noted. External audio input/output connections: - " Line In" and "Line Out" audio ports, and a "PTT" (Push-to-Talk) are provided via 3.5mm connectors to allow the connection to an external device. (devel-branch only): There is CAT function and audio-in and out also as IQ in and out via USB available. Setting of input is in main menu #60 or via long-press of M3. Line out signal levels: Nominal 1 volt peak-peak, maximum when AGC is operating. Line in signal levels: Nominal 0.1-1.0 volt peak-peak, adjustable using the "Line Input Gain" settings. Transmit ALC type: Look-ahead gain compressor with both pre-set and available "custom" settings. 410mA on 40 meters and below at 13.0 volts, approx. 440 mA on 10 meters, minimum volume, maximum display brightness. The selection of minimum display brightness can reduce this by 40-60mA. The modification to the PA drivers to switch off bias when not in TX mode can reduce this by a further 30-60 mA. Power off: - <5 mA if the PA driver bias modification is performed. If this modification is not performed it is recommended that power be disconnected from the transceiver as the PA driver transistors will be biased on even when the power is turned off, causing 30-60 mA of standing current. With modification RF-04-:-010 from German mcHF Project Group consumption in power off is <0.5uA. Transmit (At 13.0 volts power supply):at full power around 3A;at 10W around 2.5A.
