Azden AZ-61 6m FM HT - Tip #14 - Antenna

Azden AZ-61 6m FM HT

This is an article in a series regarding the vintage Azden AZ-61 6m FM Transceiver.

The Azden AZ-61 comes with 50 Ohm BNC antenna connector and a rubber duck style antenna.  An excellent way to get more out of this radio is to upgrade the antenna.  There are several 6m BNC antennas on the market or you could build your own.

KC0BIN (Rob Johnson) contacted me recently to share that he has had very good results with the Diamond RH-205 BNC antenna on his Azden AZ-61.  The antenna telescopes out to about 52.75 inches, and this length coincidentally resonates well on the FM portion of the 6M band.  Thank you Rob for this helpful tip.

Azden AZ-61 6m FM HT - Tip #9 - Scanning

This is an article in a series regarding the vintage Azden AZ-61 6m FM Transceiver.

The AZ-61 has two scanning modes: VFO mode scanning and memory mode scanning.  The various functions on the vintage AZ-61 are a challenge to operate without instructions.  Hope the information below helps AZ-61 owners master scanning on their AZ-61.

Scanning Overview

  • VFO mode scanning is between two frequencies and is programmable
    • A-bank scanning - scanning is conducted between the receiving frequencies stored in memory channels A19 and A20 using the configured frequency step.
    • B-bank scanning - scanning is conducted between the receiving frequencies stored in memory channels B19 and B20 using the configured frequency step.
  • Note: VFO mode scanning is from low frequency to high frequency.  Be sure to program the lower frequency in A19 when setting up A-bank scanning.  Be sure to program the lower frequency in B19 when setting up B-bank scanning.
  • Memory mode scanning allows scanning of memory channels and is programmable
    • A-bank scanning - scans the memory channels A01 to A20.
    • B-bank scanning - scans the memory channels B01 to B20.
    • A-B bank scanning - alternates scanning of the memory channels, A01 - A20 and B01 - B20.
    • Memory channel skill (lock-out) is possible on all memory channels.

VFO Mode Scanning

  • Make sure the radio is in VFO mode.  If the radio is not in memory mode, press the VFO key.
  • To start scanning, press the SCAN key.
  • When a signal is received, scanning stops.

Memory Mode Scanning

  • Make sure the radio is in memory mode.  M.MODE will blink on the display when in memory mode.  If the radio is not in memory mode, press the MEM key.

Azden AZ-61 6m FM HT - Tip #4 - rebuilding the battery pack

This is an article in a series regarding the Azden AZ-61 6m FM Transceiver.  One of the weak points of vintage handy-talkies (HT's) is the battery pack.  It is a fact that Ni-cad batteries (or any rechargeable for that matter) have limited useful life.  It is also a fact that radio manufacturers love to create proprietary battery packs for their radios.  If you buy a vintage HT you will likely end up having to replace or refurbish the battery pack.

Azden AZ-61 6m FM Transceiver

Replacing the battery pack on the AZ-61 with new old stock (NOS) is unlikely.  It is possible to rebuild the battery pack yourself.  The process involves carefully cracking the case (a Dremel can help with this task), replacing the batteries, and then resealing case with tape.

Azden AZ-61 6m FM HT - Tip #2 - disabling "the beep"

This post is in a series regarding the 1990's vintage Azden AZ-61 6m FM HT.

Azden AZ-61 6m FM HT

So you have dusted off  your Azden AZ-61 6m FM HT and powered it back to life.  Congratulations for giving this neat old radio a go!  One of the things you may have noticed when pressing buttons is an annoying, "beep" after each key press.  The good news is that the beep noise can be toggled off and on easily (if you know the trick).

How to toggle off and on the key press beep

Step 1) Press and hold the "FUN" key while powering the radio on.


Yes, it is that simple.

Azden AZ-61 6m FM HT - Tip #1 - How to program the radio

The Azden AZ-61 6m handi-talkie (HT) can be found from time-to-time at hamfests for a relatively low price.  Buying one without the manual; however, can be a rather frustrating experience since the radio's design is far from intuitive.  This isn't the kind of radio that you can put in your hand and program without looking at a manual.  Almost anyone who has owned one would agree that it is downright difficult to program the AZ-61 (even with the original manual).

Azden AZ-61 6m FM Transceiver
After searching the Internet, we discovered that there are rather few resources to guide the manual-less Azden AZ-61 owner in programming the radio.  As a consequence, there are probably more than a few fully functional units out there just sitting on a shelf collecting dust for lack of ability to program.  If you are one of those owners, we prepared this short tutorial on programming the Azden AZ-61 for you.  We hope it inspires you to dust-off your Azden AZ-61 (or snap one up at a hamfest), program a repeater or two, and get it back on the air.

How to program a repeater into the Azden AZ-61

In the following step-by-step example, we will program a local 6m repeater located in Ben Lomond, California (WR6AOK, output = 52.800 MHz, offset = -0.500 = 52.500 MHz, PL = 114.8) to the Azden AZ-61's memory address "MA0".

"MA0" is the main memory channel and can be recalled quickly via the dedicated MA0 button on the front left of the radio.  This is a pretty handy feature.

Step 1: Turn on the program mode

  • In order to program the radio you need to first enable the programming mode. 
  • Press "FUN" + "0" (at the same time) and hold for 1 second
  • The LCD display will show a blinking "PR"
  • Note: The programming mode is automatically turned off when the radio is left idle for 10 seconds or more.  This is an irritating "feature" since it forces you to repeatedly re-enable the programming mode (unless you are fast at going through the programming steps).  Be prepared to get a lot of practice on turning on the program mode.

Step 2: Select the memory address to program

  • For our example, we are going to program the memory address "MA0".
  • Using the up or down arrow buttons (located to the right of the LCD), select the memory address, "MA0".
  • "MA0" will appear in the upper left hand corner of the LCD when selected.
  • Press the "#" key

Step 3: Enter the receive frequency

  • For our example, we are going to program a receive frequency of 52.800 MHz.
  • Note: The AZ-61 does not have a decimal key.  Instead, use the "*" to denote the decimal when entering the frequency.  
  • Enter the frequency by pressing the keys, 52*800
  • Press the "#" key

Step 4: Enter a receive CTCSS frequency

  • For our example, we do not want to use a CTCSS frequency (not sure if the repeater transmits the CTCSS) so we are going to program this memory address to disable that feature.
  • Using the up and down arrow buttons (located to the right of the LCD), select "C00:"
  • Press the "#" key

Step 5: Enter transmit frequency

  • For our example, we are going to program a transmit frequency of 52.500 MHz.
  • Note: The AZ-61 does not have a decimal key.  Instead, use the "*" to denote the decimal when entering the frequency.  
  • Enter the frequency by pressing the keys, 52*500
  • Press the "#" key

Step 6: Enter transmit CTCSS frequency

  • For our example, we are going to program a transmit CTCSS frequency of 114.8 Hz.
  • Note: The CTCSS frequencies are stored in the AZ-61 in a table.
  • Using the up and down arrow buttons (located to the right of the LCD), select the "C16: 114.8"
  • Press the "#" key
Voila!  We have programmed a repeater into the Azden AZ-61 in just six easy steps.  Armed with these steps you can repeat the same procedure to program any of the other 40 memory addresses.  Hope this article has inspired you to put  your AZ-61 back on the air.

Considering its age, there are a surprising number of other features that can be programmed into the Azden AZ-61.  Perhaps this is a good example of how more can be less.  In the case of the AZ-61, more features seems to have led to less usability / programmability.  We may cover additional programming topics in a future article if there is interest.  Drop us a line and let us know.
