Did you try holding down the up and down arrows simultaneously while turning it back on (this is not the reset procedure). The other possibilty, although slim, was a reported rumor (I think it was on Compu$erve) that some of these radios might be subject to the new EPCA since they could receive cellular. Maybe Yaesu "fixed" the FT-530. I really doubt it though and it is probably another circuit board design change. ****************************************************************************** * Robert G.

Thanks, Peter Peter A. Stokes ______________________ Voice & Voice mail: (613) 545-2923 Engineering Applications Support ____________________ FAX: (613) 548-8104 Canadian Microelectronics Corporation ________________ Net: stokes@cmc.ca Kingston, Ontario, CANADA ________________________ Radio: VE3ZXT @ VE3CDY ------8<-------cut here------------------------------- How VE3ZXT programs his Yaesu FT530 HT (These instructions are intended to help remind me on how I program my FT530 and are not a substitute for reading the manual!) HINTS: 0. To turn the radio on, push and hold (for 1/2 a second) the orange button on the left side. 1. If you get into a strange mode or display, hit PTT as this usually clears it. The radio may display "ERR" for a moment. 2. To switch from band to band (left to right and back), use the "BAND" button. 3. If you want the backlight to stay on while using the radio, enter FM -> LAMP. The LAMP button is just below the PTT button. 4. The radio is capable of any combination of scanning, searching or being idle on both sides. For example, one can be scanning on the left side and carrying on a QSO on the right side. To make the radio scan, place the radio on any channel (push MR until the channel indicator does not have multiple small arrows) and then push and hold either arrow button. It is also possible to make the radio alternate scan (scan on the left, then right, then left, ...). 5. Push the Monitor (Burst) button (above PTT) to break squelch momentarily. Push and hold the same when the radio is off to see the seconds display on the clock. PROGRAMMING GUIDE: 0. Ensure the radio has suitable power and lithium battery installed. 1. Reset the radio by holding the MR and VFO buttons as you power up the radio. This will clear all settings, time, channels, etc. 2. Enable the extended receive and transmit modifications by holding both arrow keys while powering up the radio again. Note: extended Rx and Tx also require a hardware modification not discussed here. 3. Set the clock: FM -> REV to see the clock FM to go into set mode (then see page 51 of the manual) Hint: set the radio in UTC to avoid time zone and time change hassles. 4. Enable ARS (Automatic Repeater Shift) on both bands. This will automatically set the repeater offset to the correct frequency count and direction +/- when you program in a frequency. The radio understands the basic amateur bandplan and will not set an offset if you enter a simplex frequency (e.g 146.520). FM -> 0 -> 6 -> FM -> 6 and again for the other band FM -> 0 -> 6 -> FM -> 6 5. Set the alternate display (when only working one band) to display battery voltage (a nice feature IMHO!): FM -> 0 -> FM -> BAND and again FM -> 0 -> FM -> BAND Alternative displays include blank (---) and clock. 6. Set transmitter default power to high: FM -> 3 7. Set scan resume mode on both bands to "P" for pause (as opposed to "5" which causes the radio to continue scanning after five seconds on one signal): FM -> 7 -> FM -> 7 and again for the other band FM -> 7 -> FM -> 7 8. Set automatic power off if desired: FM -> 0 -> 3 -> 3 This feature can be useful if you want to conserve battery power or a pain if you are using the radio as a scanner or for packet monitoring. Note that the radio will shut itself off when battery voltage reaches near 5.5volts, eliminating the possibility of over-discharging your nicads. As the radio nears this shutdown condition, the display will alternate between normal functions and a battery voltage display. 9. Set ABS to the desired ratio. ABS is the Automatic Battery Saver and causes the radio to go into a low- power consumption sleep mode if it is not used for a few seconds. In this mode, the radio remains inactive (conserving power) except for periodic 30 millisecond samples of the frequency being monitored. ABS may cause you to miss the first split second of a transmission and can cause problems for the same reason when the radio is being used for packet. Otherwise, it is a good tool. If I had the money, my car would have ABS too (but that is a different kind :-) To set ABS, enter: FM -> 4 and then one of the following keys 1 for 10ms sleep, 30ms sample duty cycle 2 for 20ms sleep, 30ms sample duty cycle 3 for 40ms sleep, 30ms sample duty cycle 4 for 80ms sleep, 30ms sample duty cycle 5 for 160ms sleep, 30ms sample duty cycle 6 for 320ms sleep, 30ms sample duty cycle 7 for 640ms sleep, 30ms sample duty cycle 8 for 1.28s sleep, 30ms sample duty cycle 9 for automatic ratio based on recent usage 0 for ABS off 10. If desired, enable Tx Save feature. This feature will adjust transmitted power based on the signal strength of the incoming reception. As a rule, amateurs should always be using the minimum power necessary to maintain their QSO. This is a lazy approach. To enable Tx Save: FM -> 0 -> 4 and repeat for the other band FM -> 0 -> 4 11. Program in your favorite frequencies in all the channels. There are 41 per band: 38 channels plus one CALL channel plus one U (upper channel) plus one L (lower channel). If you have enabled the extended receive and transmit, you will find that a wide range of UHF and VHF frequencies can be intermixed on each side. It is also possible to enter 0.8 GHz frequencies in the UHF side! If the frequency display is flashing, the PLL has unlocked and the radio is unable to tune that frequency. The basic sequence to enter a frequency in a channel is: VFO enter into either VFO on the band desired 146940 to enter 146.940 MHz FM (hold for two seconds) (use arrow keys or dial to select channel to store frequency in) FM The frequency is now stored. After a second or two, the radio mode returns to the VFO. Repeat this process as necessary to enter all frequencies. Refer to the manual on the programming of the CALL, L and U channels. These are used for a quick recall of the CALL frequency, Lower limit and Upper limit when searching, respectively. Note that if a CTCSS tone is stored in a U or L channel, that tone will be used for decoding during search mode if searching is initiated from that channel. To set a CTCSS decode frequency on a given channel: set radio on that channel FM -> 2 turn dial to desired PL tone 2 Refer to the manual on setting a decode frequency or scanning for a decode frequency. To set a CALL channel frequency: VFO enter into either VFO on the band desired set frequency, offset and CTCSS tone FM (hold for two seconds) CALL The radio is capable of receiving in AM mode and has extended receive capability down into the aircraft band. Although not discussed in the manual, the radio can store the mode (AM or FM) in each channel. To store a frequency in AM mode: VFO enter into either VFO on the band desired set frequency FM -> 0 -> FM -> VFO (enables AM mode) FM (hold for two seconds) use arrows or dial to select channel FM Note: the VFO will remain in AM mode until you enter the sequence again (FM -> 0 -> FM -> VFO) or the radio is made to listen to an FM channel. Remember to return the VFO to FM mode after setting an AM station otherwise you may end up programming all remaining channels in AM mode (annoying!). Important: If you enter any frequency other than an amateur radio frequency, make sure you manually set the offset to - or + so that if you are listening to the frequency and accidentally PTT, you will not transmit on that frequency (e.g. a police frequency!). 12. Set IBS (Intelligent Band Select) if desired. This makes the radio automatically switch to the side, when you PTT, that last had a transmission. To set: FM -> 0 -> BAND Note: both bands must be displayed to set IBS. 13. Set DTMF keypad transmit hang time to on: FM -> 0 -> FM -> 1 This makes it possible to enter a DTMF number sequence (e.g. a phone number during an autopatch operation) without having to hold PTT beyond entering the first digit.

My participation was limited to listening since I haven't gotten around to fixing a little transmitter problem yet. I must do that soon. I flipped on my old Mastr Pro about 8:00 PM EDT and a few minutes later it began to burp as some weak signals broke the squelch on 52.525. Within ten minutes traffic was getting heavy and after about an hour the radio settled into a screech and roar pattern as everyone tried to talk at once. This lasted for about half an hour before I finally started hearing one side of two or three conversations at a time. Once I even heard both sides of a QSO. Most of the stations I heard from here in central North Carolina were 8's and 9's, with Wisconsin and Illinois the most reliable. A few Ohio stations came in off and on. I also heard a couple of 0 stations and considered eating the mike when I heard most of one call from a VE. I've got to get that transmitter fixed. The band finally died about midnight and has been dead ever since when I was listening. The sporadic E season has arrived.
