5.6.1. Power button

Momentarily pressing power button (1) will turn the HAMlab ON. It normally takes 30s from the button press until the HAMlab is ready to be used. Once HAMlab is ON, holding the power button pressed will cause the proper shut down of the device. Blue LED indication on the power button indicates that device is turned on.

Note

In case that system halts and becomes unresponsive, device can be turned off by holding power button for a few seconds / until the blue LED is turned off.

5.6.2.2. CW Key / paddle jack

The CW key/paddle jack (3) is a ¼ inch TRS phone plug. Tip - DOT Ring - DASH The common is connected to the sleeve.

Note

3.3V Max input.

For an iambic paddle, the tip is connected to the dot paddle, the ring is connected to the dash paddle and the sleeve is connected to the common. For a straight key or a keyer output, connect to the tip and leave the ring floating. The common is connected to the sleeve.

Note

Currently keyer is not supported by software. Software support for it will be availabe in one of incomming software updates.

5.6.2.3. Phones

The HAMlab 80-10 10W supports a stereo headset with headphone ¼ inch TRS phone plug (4) . Mono or TS connector that grounds the “ring” portion of the connector should not be used!

5.6.2.4. Logic analyzer

0-7 are logic analyzer inputs. G - common ground.

Note

Logic analyzer inputs (5) can only be used when running Logic analyzer WEB app.

5.6.2.5. Oscilloscope

(6) - IN1 (7) - IN2 (8) - EXT. TRIG.

IN1, IN2 and EXT. TRIG. are oscilloscope inputs.

Note

These inputs are active and can be used only when Oscilloscope+Signal generator WEB application is running.

5.6.2.6. Signal generator

(9) - OUT1 (10) - OUT2

OUT1 and OUT2 are signal generator outputs.

Note

These two outputs are active and can be controlled only when Oscilloscope+Signal generator WEB application is running.

Note

To get expected signals from the signal generator, outputs must be 50ohm terminated.

5.7. Back panel controls and connections

../_images/4.7._Back_panel_controls_and_connections.png

5.7.1. ANT - TRANSCEIVER ANTENNA PORTS [1,2]

ANT1 (1) is SO-239 50 ohm connector, while ANT2 (2) is BNC 50 ohm connector.

User can connect transmitter output to ANT1 or ANT2 by properly connecting SMA cable inside the chassis to one of ANT connectors. Software switching between ANT1 and ANT2 is not available in HAMlab 80-10 10W version.

Danger

THIS UNIT GENERATES RADIO FREQUENCY (RF) ENERGY. USE CAUTION AND OBSERVE PROPER SAFETY PRACTICES REGARDING YOUR SYSTEM CONFIGURATION. WHEN ATTACHED TO AN ANTENNA, THIS RADIO IS CAPABLE OF GENERATING RF ELECTROMAGNETIC FIELDS WHICH REQUIRE EVALUATION ACCORDING TO YOUR NATIONAL LAW TO PROVIDE ANY NECESSARY ISOLATION OR PROTECTION REQUIRED, WITH RESPECT TO HUMAN EXPOSURE!

Danger

NEVER CONNECT OR DISCONNECT ANTENNAS WHILE IN TRANSMIT MODE. THIS MAY CAUSE ELECTRICAL SHOCK OR RF BURNS TO YOUR SKIN AND DAMAGE TO THE UNIT.

5.7.2. AUX1

RX1 IN - direct feed to the first receiver pre-amp and attenuators.

RX1 OUT - an output from the antenna feeding

By default HAMlab 80-10 10W comes with loopback cable connected from RX1 IN to RX1 OUT. User can also use this two connectors to insert external filters or preamplifier.

Note

This input is not protected by any ESD circuitry, therefore device connected to the RX1 OUT Output is susceptible to possible damage by ESD from an EMP event if the connected device does not have adequate ESD protection circuitry.

Warning

Be aware that Preamp1 and Preamp 2 are both wide band amplifiers covering the whole bandwidth of 55MHz. It is not recommended to use the Preamps on a large Antenna without a Preselector connected (this would cause overload and intermodulation from strong broadcast signals outside the Amateur Radio Bands)!

5.7.3. AUX2

RX2 IN - secondary 50ohm receiver input that can be used as a second panadapter in Power SDR software or to as feedback signal for pre-distortions (Pure Signal tool).

XVTR (TX2 OUT) - secondary transmitter can be used to drive external PA Max. output power is around 10 dBm @ 50ohm.

However, currently there is no support in HPSDR for a second TX output.

5.7.4. Power and Fuses

The HAMlab 80-10 10W is designed to operate from a 13.8 volt nominal DC supply and required at least 4A.

Danger

This unit must only be operated with the electrical power described in this manual. NEVER CONNECT THE +13.8VDC POWER CONNECTOR DIRECTLY TO AN AC OUTLET. This may cause a fire, injury, or electrical shock.

The HAMlab 80-10 10W requires 13.8 VDC @ 4 A measured at the radio in order to transmit maximum wattage. Multiple power cable connections between the power supply and the HAMlab 80-10 10W, a poorly regulated power supply, undersized power cable and very long power cable lengths will result in a voltage drop, especially under load. Any voltage deviation from 13.8 VDC will result in lower power output that the 10W nominal specification.

For best results, select a linear or switching power supply that is well regulated and free of internally generated radio frequency noise. “Birdies” generated by a poorly filtered supply can often appear as signals in the Power SDR Panadapter display.

The Anderson Powerpole™ connector contains 45 Amp pins to minimize voltage drop during transmit. The RED connection should be connected to the positive (+) lead of the power source. The BLACK connection should be connected to the negative (-) lead of the power source.

I - If you choose to use your own Powerpole cabling, be sure to properly size the wire and the Powerpole connector to minimize voltage drop during transmit. Excessive voltage drop can cause lower transmit power output levels.

There are two internal fuses in the HAMlab. One is protecting whole system while the other one is just for the transceiver. If you ever need to replace the internal fuse, remove the top cover and the shield of the power board.

../_images/IMG_20161202_105403.jpg ../_images/IMG_20161202_105424.jpg

Danger

FUSE CURRENT RATING SHOULD NOT BE HIGHER THAN 3.15A AMPS! FAILURE TO PROPERLY USE THIS SAFETY DEVICE COULD RESULT IN DAMAGE TO YOUR RADIO, POWER SUPPLY, OR CREATE A FIRE RISK.

5.7.5. Chassis ground

This is a thumbscrew for attaching an earth ground to the chassis of the radio. Grounding is the most important safety enhancement you can make to your shack. Always ground the HAMlab to your station RF ground using high quality wiring with the length being as short as possible. Braided wire is considered the best for ground applications. Your station ground should be a common point where all grounds come together. You will likely be using a PC and a DC power source so be sure to ground these devices together as well.

5.7.6. AUDIO

Audio USB connector USB 2.0 Cable - A-Male to Mini-B must be used to connect HAMlab audio sound card with the PC in order to be able to use Phone, MIC and speaker connector for voice communication.

Note

USB connector is only available on HAMlab 80-10 10W model. For new models audio codec is used / audio is transferred over ethernet.

Speaker connector 1/8” TRS stereo connector can be used to connect stereo powered computer speakers.

Note

Do not use a mono or TS connector that grounds the “ring” portion of the connector.

5.7.7. CTRL

DB9 connector is used to control external equipment. PTT OUT relay is connected between pins 6 and 7.

Note

Other pins are at the moment not in use and should be left unconnected.

5.7.8. DATA

LAN This is network connection to the HAMlab. It is an auto-sensing 100 megabit or 1 gigabit Ethernet port that enables you to connect HAMlab to your local network or directly to PC.

USB This USB port is used to connect WIFI dongle when user would like to connect to HAMlab wirelessly.

Note

Recommended WIFI USB dongle is Edimax EW7811Un. In general all WIFI USB dongles that use RTL8188CUS chipset should work.

SD card HAMlab software is running from SD card.

Note

HAMlab comes with pre installed SD card HAMlab OS. Upgrade can be done using OS upgrade application from the HAMlab application menu and there is no need to remove the SD card. Therefore user should remove the SD card and reinstall SD card software only if system gets corrupted or stops working due to SD card failure reason. In this case only official HAMlab OS should be installed on the SD card for proper operation.
