Yaesu FT-1500M introduction permalink: http://www.amateurtele.com/index.php?artikel=212&id=#919 The Yaesu FT-1500M was my first radio I bought. I bought a new one and I love(d) it. Since it's "only" VHF I bought a Yaesu FT-897 and due to other reasons I sold my FT-1500M. Since it's out of production, it's quite rare to find. After ten years (anno 2016) I managed to buy a second hand one and I very happy with it! inside view permalink: http://www.amateurtele.com/index.php?artikel=212&id=#967 description permalink: http://www.amateurtele.com/index.php?artikel=212&id=#1424 The FT-1500M is a VHF (2 m) radio built like a tank. It's introduced in the second of februay 2002, well that's the FCC approval date... It's made of two die cast aluminium pieces and the electronics is sandwiched between them. It has the basic "modem" functionality you "need" these days like CTCSS en-/decoding, DTMF e-/decoding, 130 alphanumeric memories, backlit display and a packet connector at the back of the radio. Altough it has the modern functionality, it's very easy to operate and "simple". The FT-1500M should be seen as a basic simple radio. passively cooled and power handling permalink: http://www.amateurtele.com/index.php?artikel=212&id=#1425 I like that it's passively cooled. No annoying fan noise and gathering of dust. The radio can out 50 Watts. Although it can handle 50 Watts, this doesn't mean it's built to handle this much of power (heat dissipation) for a long time. If you you need a radio for (nearly) continuous operation or long high power transmissions, this is not the radio for you. A fan cooled radio would be wise in this case. The FT-1500M performs well for mobile/repeater operation in the mid power range. It can handle 50 Watts of high power operation, but remind that transmission time should be reduced to precent access heat generation. features permalink: http://www.amateurtele.com/index.php?artikel=212&id=#1426 5, 10 ,25 or 50 Watts selectable rf power output 137...174 MHz receiver operation 50 tone CTCSS en-/decoding (settings can be stored per chanel) CTCSS tone scan feature for determining the received CTCSS code mini din (DB9) port for (1200/9600 baud) modem operation (APRS/D-STAR/...) external 3,5mm audio out/speaker connection standard DTMF microphone 130 "regular" alphanumeric programmable memory channels (including settings like power) 9 pairs of band edge memory channels (for scanning between two set frequencies) "home" channel button for direct access to the programmed favourite chanel 10-channel NOAA Weather Band Memory Bank (no weather broadcasts available in Europe) Supply voltage display at startup TOT; Transmission Time Out Timer (time selectable in menu) APO: Automatic Power Off (time selectable in menu) Automatic repeater shift (depends on region version) S-meter RF squelch Bell alert CTCSS paging Priority channel revert during scan specifications (by Yaesu) permalink: http://www.amateurtele.com/index.php?artikel=212&id=#1427 TX frequency: 144...148 MHz / 144...146 MHz (depending on country) RX frequency: 137...174 MHz Channel Step: 5/10/12,5/15/20/25/50/100 kHz Frequency Stability: Better than 10 ppm (20 to +60 'C) Mode of Emission: F2 (FM data with subcarrier), F3/G3E (analog FM/PM) Antenna Impedance: 50 Ohms unbalanced Supply Voltage: 13,8 VDC (+/-10%) negative ground (12,42...15,18 VDC) RX current: < 600 mA (signal) RX current: <300 mA (squelched) TX current: 8 A @ 50 W / 6 A @ 25 W / 3 A @ 10 W / 2 A @ 5 W Operating Temperature Range: 20 to +60 'C Case Size: 127 mm wide, 35 mm high and 126 mm deep Weight: 990 grams Output Power: 5, 10, 25 or 50 Watts (selectable) Maximum Deviation: 5 kHz (wide) or 2.5 kHz (narrow) Spurious Radiation: Better than 60 dB Microphone Impedance: 2 k Ohms Receiver circuit type: Double-Conversion Superheterodyne Intermediate Frequencies: 21,7 MHz and 450 kHz Sensitivity: Better than 0,2 V (for 12 dB SINAD) Selectivity: 6 dB @ 12 kHz and 60 dB @ 28 kHz IF Rejection: Better than 70 dB Image Rejection: Better than 70 dB Maximum AF Output: 3,5 W into 4 Ohms @10% THD service menu permalink: http://www.amateurtele.com/index.php?artikel=212&id=#1428 Advice: Don't try to read/edit the service menu without the service manual! The service alignment menu is rather complex since it's operated 'blind'. Without proper instructions alignment is a lost cause. (I've been there...) perfect fot APRS/packet! permalink: http://www.amateurtele.com/index.php?artikel=212&id=#1429 This rig is perfect for APRS! Luxury options like DCS, digital modes and so on are not available, but also not needed. There's no noisy fan and since APRS packets are small, the TX time (and head generation) is rather low. Therefore no fan is needed and the rig stays cool. There's also a packet connection woth all the desires TNC connections! Therefore the rig can me used for APRS (packet) without a microphone which could disturb the packet data. Im my case I programmed only one local APRS frequency of 144,800 MHz. Then I locked the key and dial but not the PTT, otherwise the rig can't transmit. After that the rig is set to 'memory only' mode and removed the microphone. The result is that the rig can't be 'disturbed' by human interaction otherwise than turning it off of entering the menu. All the other buttons don't affect the packet operation. (Not intended) frequency changes are therefore avoided. display test permalink: http://www.amateurtele.com/index.php?artikel=212&id=#1430 It's possible tot perform an automatic display test. During the test all the display segments, backlight and RX/TX led are tested. The test steps are shown below: 1. Turn the FT-1500M off. 2. Press and hold both [D/MR] and [REV] keys. 3. Press the [PWR] button. 4. Release all three keys when the display turns on. 5. The display test is now active. 6. Press the [MHz] key momentarily to stop the display test. 7. The rig is now ready for normal operation. Source: Gilles, VE2GIQ wideband modification permalink: http://www.amateurtele.com/index.php?artikel=212&id=#1431 It's possible to perform a wideband modification. But it has no use and you will lose some features like the auto repeater shift and default channel steps. And transmitting out of band is illegal. For 70 cm transceivers this could be convenient for testing 446 MHz (PMR band) equipment, but a wideband modification for a VHF rig is only interesting for illegal purposes. Therefore the wideband modification is not explained here... I bought a rig with the wideband modification. After 'resetting' the wideband modification, the original settings became active! The original settings of the frequency span, auto repeater shift, repeater offset and channel steps came back. Now the rig is in it's original state. Some rigs lose the settings after the wideband mod and after restoring the original region settings, some settings don't come back... The FT-1500M can be restored completely. If the ARS (Auto Repeater Shift) can't be changed and the frequency span is wider than the regional transmit limits, the rig is modified. open de afdrukbare pagina door hier te klikken klik hier voor de mobiele versie.
