Introduction
Thank you for purchasing a HobbyPCB IQ32 transceiver. On behalf of all our design and de-
velopment contributors, we appreciate your support of our products.
The HobbyPCB IQ32 is a 5 Watt Software Defined Radio. It operates on all amateur radio fre-
quencies from 80M up to 10M. Native operating modes are USB, LSB, CW and PSK31. There
is a built in keyer for CW operation and a PSK encoder and decoder for PSK operation.
The IQ32 does not require an external computer to take advantage of all the features.
The operating firmware of the IQ32 is easily upgraded by downloading the latest firmware to a
memory stick. The memory stick is connected to the USB port on the radio and the radio han-
dles the upgrade.
Connect a suitable antenna or dummy load and a power supply. Remember, you are respon-
sible for the radio, and you must ensure that any emissions are on a proper frequency (one for
which you are properly licensed and allowed to transmit).

Rotary Encoders
Rotary encoders have 3 possible methods of operation:
1. Rotating the knob clockwise or counterclockwise will increase or decrease the desired
parameter.
2. Pressing and releasing the knob will change a specific parameter.
3. Pressing, rotating and then releasing the knob will increase or decrease a parameter or
select a new sub function, which may only be available while the knob is pressed.
Right Rotary Encoder –Frequency Control
•Frequency Adjustment - rotate
•Press, rotate and release
oChange the frequency step size: 1, 10, 100, etc Hz
The right rotary encoder, on the front panel, selects the desired operating frequency for trans-
mit and receive. It is also used to calibrate the touch screen and to initiate a firmware upgrade.
Left Rotary Encoder
•Rotate –adjust AF gain: 0 to 100. Other parameters are adjusted with this control.
•Press and release –change filter bandwidth.
•Press, rotate and release –select a new function to be adjusted
The left rotary encoder below the touch screen is mainly used as the AF gain control. Other
functions such as Mic Gain, TX Level, Sidetone gain are also available on this control. It is
used for parameter selection in many of the setting functions. Pressing and releasing this con-
trol while in receive mode will change the audio filter bandwidth.

Firmware Upgrade
The latest released executable images are posted on GitHub at following link:
https://github.com/ve7pke/IQ32-Files
•Download the most recent zip file and save it to a safe location on your computer. Unzip
this file.
•Place the image.bin file in the root of a USB flash drive having a capacity of 4GB or less.
•With the IQ32 powered off, insert the USB drive into the USB connector on the right-
side panel of the IQ32.
•Press and hold down the frequency encoder while powering on the IQ32.
•The screen will remain white - you can release the encoder and wait for the unit to finish
loading (~15 s).
•Once the program has loaded, the unit will automatically boot into normal operation.
•Check the new build version and date on the splash screen during boot.
Public Source Files
Source files are located on GitHub at the following link:
https://github.com/iq32-sdr/Source
Building your own image from the source files is not encouraged unless you are experienced
with proper operation of the compiler.
Caution: Installing modified firmware could brick your device unless you know what you are
doing. Writing the binary file directly to ROM will overwrite the factory installed bootloader and
will prevent the loading of released firmware via a USB flash drive.

Operation
Turn on the power switch located on
the right-side panel. You will see the
SPLASH SCREEN as depicted in Figure
4. It announces the version of the
software you are running. This pic-
ture shows the current version at the
time of preparation of this document.
We expect the software will continue
to evolve, and it is always possible
that there has been an update to the
firmware that has been released be-
tween updates to the documentation.
After a few seconds, you should see
the screen pictured in Figure 5. It is
the HOME SCREEN.
From here you can start your journey,
at each subsequent power-up, you
will be returned to the HOME SCREEN
after the SPLASH SCREEN is briefly
displayed.
The software has multiple screens
that are accessed by touching the
appropriate place on the touchscreen.
These widgets are multifunction. The
top line indicates the name of the
widget, what secondary screen or
function it selects, what option is cur-
rently selected and the value of the
option. These are all in a touch sensi-
tive area on the screen.

Non-Volatile Memory
Most configuration and operating parameters are saved in non-volatile memory. As you config-
ure the IQ32 on the varied setting screens, program screen function key operations and key-
board Fn key operations, these settings are preserved for future use. When the power is
turned off and later restored, the value of the many parameters retrieved from memory are the
same as previously defined.
Frequency of operation, mode, filter, AGC, split frequency, Tx Level and frequency increment
step size are saved in the last selected memory location, Memory 1 –Memory 14. These
memory locations are discussed in a later section of this manual.
The offset frequency, typically used for transverter operation, is also saved in this memory.

Home Screen
The following features are displayed
on the Home Screen, Figure 6:
•Filter selection: As shown in the figure to the right, the selected filter is
F3 (300 –1300 Hz) and the relative bandwidth is shown by the yellow
bar under the spectrum display.
•S Meter: In the figure to the right, the S Meter reading
is S6 and the signal strength is shown by the green
bar under the spectrum and filter.
•AGC: Just below the S6 in the figure to the right, the AGC selection is CW.
AGC operation will be described in a later section of this manual.
•Call and Name: For CW and PSK operation, the but-
tons shown at the right are displayed on the HOME
SCREEN. With a PS2 keyboard attached to the IQ32 you may enter the call sign and the
name of your contact. They will be transmitted as configured for the keyboard Fn keys.
This is discussed in a later section of this manual.

Mode Selection
Figure 7 is the Mode icon or Mode widget. Pressing it will bring you to the
MODE SELECTION SCREEN. The current mode is PSK-U (PSK in USB) and we
are currently in Receive (RX). If you touch the Mode widget (upper left cor-
ner of the screen) you will switch to the MODE SELECTION SCREEN (Figure 8,
depicted below).
Mode selection may also be accomplished by pressing, rotating to the de-
sired parameter and releasing the left rotary encoder.
On the MODE SELECTION SCREEN, you
can select the operating mode you
desire, by touching the appropriate
on-screen button. It will switch to the
desired mode and the mode’s HOME
SCREEN. If you selected the wrong
mode, you must hit the Mode button
(Figure 7) on the HOME SCREEN to
return to the MODE SELECTION
SCREEN. Then select the desired
mode.
Touch the LSB (USB) button (Figure
9) to go to the LSB HOME SCREEN
(Figure 10).
Once on the LSB HOME SCREEN, or
any HOME SCREEN, you can either
operate the radio, access the
MEMORY MANAGER (LO Freq. widget),
or access the SETTINGS SCREEN.
The frequency of operation is now
displayed in large green digits be-
tween the FFT window (waterfall or
spectrum display) and the widg-
ets/buttons on the bottom third of the
screen. This is true for not only the
LSB HOME SCREEN as shown in Fig-
ure 10, but also on the USB HOME
SCREEN, the CW HOME SCREEN, and
the CWR HOME SCREEN.
