Icom 775Dsp Serial Numbers
ICOM 775 DSP SERIAL Amount ICOM 775 DSP SERIAL Quantity (1/1) RICHARD STROBEL: IM THINKING OF Purchasing A IC 775 DSP TRANSCIEVER. Will ANYONE KNOW WHAT THE SERIAL Amount FROM THE Best and newest PRODUCTION RUN WAS. Thanks a lot Frank: Icom 775't have been out of creation for about 3 years today. A few dealers had old stock to sell up until Dec of 2002. The highest serial amount that has been sold has been in the 3000 - 3100 range. Unlike several radios, the 775 DSP never ever acquired a ' season / production run ', code constructed into the serial number. Icom may of had different runs of serial amounts for different parts of the globe.
I feel not certain of that for a reality. It does appear like Icom started the serial amounts at # 1000. I have never noticed, or heard of a serial number lower that # 1000 on the 775 DSP. Real the same is genuine of the lcom 781.
I have never noticed or heard of a 781 below # 1000. These seem to become the only two radiós by any óf the big three to become numbered this way.
I have been told to look for a Icom 775 with the 2 or higher serial numbers and was wanting to know why that is. Thanks for your time. The serial number prefix begins with '1' e.g. 1201234 (US/Canada), 1301234 (EU), 1701234 (UK). The previous serial number ranges begin with '0' e.g. 0201234 (US/Canada), 0301234 (EU), 0701234 (UK), and have the earlier PA200W (2 X MRF150) and FILTER Units.
There had been six main improvements to the icóm 775 DSP. All of these upgrades were included into the production operates, after serial amount # 2000, but I would look for a model with a serial amount above # 2200 to end up being sure. I have possessed 4 775 DSP'h. Two were between # 1000 and # 1300, and two had been above # 2700 ( still have one of thosé ). I can state that all preformed about the exact same.
I have never seen any of the ' horror ', problems that others on eham possess reported. The just glich that I have found, and that has been documented, is usually the very, very uncommon bleed over from the 2nd VFO, in the dual watch mode.
THIS 0NLY HAPPENS, when á incredibly ( unusally ) solid signal happens to become on the second VFO't freq. It has never become usually or awful more than enough to make me need to sell the stereo, or poor mouth it. Very user pleasant radio. Great service track record. Great audio, both on réc and xmit.
Extremely simple to go through display. A lot of energy. If you set up the Feel filtration system, you can listen to SSB in the wide setting. It'beds about 4 KC broad and really good if the band is not to hectic. I have got all the filters installed, and they all work just excellent. You may or may not require them. At one period 2 years ago I had right here on the desk, ( all at the exact same time: Icom 781 Icom 775 DSP Yaesu Foot 1000D Yaesu Foot 1000 Tag V Kenwood TS 950 SDX Kenwood TS 2000 Icom 756 Professional I Icom 756 Pro II ALL are usually now eliminated, except for thé 781, 775 DSP, and the TS 2000 The TS 2000 is certainly my all round general DC - lighting stereo.
Saves me from getting to buy VHF and UHF all setting rigs. The 781 is certainly a great radio, but the 775 DSP can be nicer sounding. Enjoy and have fun. Radio Bob Bob Hardie: Hello there, anyone, and possibly I need some help on my lcom 775DSP.
If you can help me or steer me to help. Very first, I are a qualified tech/engineer on a great many advanced items of products. However, this is certainly the first 775 I've worked well on. Understanding it is definitely a task.
It gets good. And transmits 200 watts, but its transmit indicators are not on appropriate freqs. For example, on 14.2MHz, it's actually sending 14.8Mhz. Additional freqs are usually even further off. Sometimes on 7.2MHz, it appears to work on the correct freq. After that, it goes off freq once again. Have eliminated back the rf collection, checking and would up back at IC8 ón the IF plank.
No 455 KHz on SSB or nothing right now there. CW is 455.9 KHz, AND Have always been and FM are nada darn point as well. I examined the four DDS quests (PLL Board) and they are usually intended to end up being 14.1 MHz out at 2 VP-P. In transmit they are actually 438 Khz, 1.35 VP-P. In receive, they are usually 10,737 Khz, 2.25VP-P (Notice that I taken out the travel to the final amps, loaded the travel cable connection with a dummy load and final out with a dummy weight as I noticed the away put caused problems with with my Times10 range/freq kitchen counter psychic readings.) So I proceeded to go back to the PCK time clock nick on the Primary plank.
It'beds crystal osc is at 9.83039 MHz @ 2.5V P-P and is usually expected to be 9.8304 MHz @ 3 VP-P. Quite close.
Nevertheless the PCK transmission out of the 100 pin IC, pin number 63 is certainly non existent. This PCK signal clocks all fóur DDS My pride retains me functioning on it as I understand I could send it in to an public Icom maintenance, etc. I've determined that as I retire, very shortly, that I feel heading to fix equipment for my day job.as I possess to keep occupied. Been a TV/Radio Fundamental Professional for over 50 decades right now.
Sorry, therefore wordy. A lot to inform. Say thanks to you extremely very much if you(anyone) can assist me. Chad Hardie, W5EUQ, Tampa, FL 813-880-8182 wk 813-477-6786 Mobile Selection 0.

Thanks a lot Chad: Icom 775'beds have been recently out of manufacturing for about 3 decades right now. A few dealers had old stock to market up until Dec of 2002. The highest serial quantity that has been sold had been in the 3000 - 3100 range.

Unlike several radios, the 775 DSP certainly not acquired a ' yr / production operate ', code constructed into the serial number. Icom may of got different runs of serial quantities for various parts of the globe.
I was not certain of that for a fact. It will seem like Icom began the serial numbers at # 1000.

Pretty user helpful radio. Great service monitor record. Excellent sound, both on réc and xmit. Extremely simple to examine display. Lots of power. If you install the Was filter, you can listen to SSB in the wide mode.
It'beds about 4 KC wide and really good if the music group is not really to occupied. I possess all the filters installed, and they all work just excellent. You may or may not need them.

Very first, I feel a experienced tech/engineer on a good many advanced items of products. However, this will be the initial 775 I've proved helpful on. Studying it will be a task. It receives good. And transmits 200 watts, but its transmit signals are not on proper freqs.
