There are several different mods to extend the transmit and receive of this radio; the one you use will depend on the region your radio is designed for. TX Modification. All region TX mods require you to remove the bottom cover and remove diodes D and D After modification, TX range is:. RX Modification. For the Americas version of the radio, no mods are necessary for complete RX coverage. European radios require removal of D and then the key sequence; Asian radios only require the key sequence.

The key sequence is as follows:.

You may find it easier to access the diodes by setting radio up on its right side. The bottom 4 diodes in each column are offset slightly to the right as pictured below. The diodes in the left column must be configured exactly as shown below. This means that you may have to add or remove diodes in the left column depending on where you purchased your IC USA radios are easy to modify as the only change is to remove D If you have to add diodes, try to use the ones that you had to remove and make sure to install them in the correct direction-they ARE Surface Mount Devices :.

Marine Products.CPU Reset Procedures. CPU reset returns the radio to out-of-box condition: all memory channels are erased, all items in the set mode returned to default values, and all VFOs cleared.

CPU reset procedure usually involves turning the radio off, pushing and holding specific buttons, and then turning the radio back on while still holding down the button combination. Some newer radios have a "partial reset" available, as well as a full CPU reset.

Partial reset will clear the VFOs and return the set mode items to default, but it will not erase the memory channels. Release the buttons after the display returns to normal. ICAT - Serial numbers below push the button on the main circuit board next to the lithium battery.

Better X axis tensioning, which is poor on the stock machine or Y axis tensioning which is completely non existent. To summarize the features would be a disservice to the magnitude of benefits but I must keep the article from becoming a complete documentary.

The best way to describe the Bear mod in the ocean of upgrades is this is your one stop full upgrade. As of posting this article Greg has upgraded the following major improvements have been made:. In all this is a well supported upgrade for your already existing system and if assembled with care allows for better overall management of alignment which can produce superior prints, allows for faster printing, and is far easier to service.

There will be a future Bear upgrade list since the platform itself is highly customizable and Greg continues to update all the parts and designs bettering the system each and every iteration. Bondtech is the king of geared extruders in the 3D printing arena and for good reason.

They make a solid product with gearing, use Nylon SLA to keep the extruder mass down and the ease of production up, and work with the community to improve the designs. Specifically the Bondtech extruder for our Prusa printers had a long list of community members involved in the process of making it an excellent upgrade for most users. So who is this for and what exactly does it do?

Prusa used the Bondtech filament gears in their extruder design but left out the best part which is the gearing. A geared extruder reduces printing artifacts by stretching those aberrations out over 3x the area so smoother prints and with the 3x the resolution you can print finer detail than you could with a extruder.

Will you see dramatically better prints? Will you see better prints? In some instances the quality can be the same or worse since this will eliminate one issue uncovering others so be careful when you switch to this extruder or any geared extruder for that matter to make sure everything else is in proper order.

Loose belts, bad hotend assembly, improper cooling, lack of PID tuning of the bed and hotend after install, Z axis alignment, and so on will be more apparent after this since the accuracy is higher. Just to note that the Vecko J carriages will fit on the Bear X axis and vice versa. Geared extruders are my all time most suggested upgrade for any printer be it a Prusa or a Tevo.

Gearing always helps and there reason are plentiful. There are add-ons and full on extruders designed by amazing community members that can vastly improve your print quality vs anything Prusa has to offer. If you need a place to start these are great options and you will see immediate changes to your print quality swapping to a geared extruder.

Some Icoms have a serious problem of ALC overshoot where you set the power to a low level to drive an amplifier, say 20w, but when you first key up the radio peaks at over w before the ALC engages and brings the power down to 20w.


Have you tested your mod to see if it causes an overshoot problem? No I did not. It was not the target of the mod, BUT as far as I know from friends some of them reporting "spikes" in out of box. BTW, signing with a ham call is nothing to be ashamed of ;- Good luck 73!

The Regard my friend. Many thanks, great job!!!! It's just that I wanted. It's horrible to have to shout sticked at the mic in order to get only 30w. I'm trying to do the mod, it seems so simple. Not so much as a peak power put the average seems ok too with my normal speaking voice and not just whistling. Making more test and gathering reports tonight.

This Type of Mod was also popular with other rigs like the TS The Mod doesn't change the maximum output. It changes the average talk power.

It's called the time constant Two different things. Many Hams are tinkers. Of course you're right. And I'll say this is obvious. Modifying radios is not a thing to newbies, so "low SSB power" is kind of mental shortcut.QRZ Forums.

Anyone interested? W2NSAug 17, If so, the exact same radios were carried, and called GE Marine radios. The actual radio is produced in Japan. They are also called Sailor Radios. I have had contact with a few other hams that have TRP transceivers. If you are not familiar with these transceivers, they are very rugged, easy to service, and RS controlable. I used to operate these back when I wend to sea nearly 15 years ago, and recently picked up the equipment second hand.

It appears that ship companies are in the proces of upgrading their ship's radio stations and since these units have been discontinued by Skanti now Thrane and Thranemany of the service shops are promoting newer equipment. W2NSSep 8, Although I have not even seen the radio in question, it is true that a lot of ship lines are getting rid of older, but totally functional, marine radios.

The neat thing about the Marine radios intended for commercial service is that they normally can be programmed for extra frequencies, even the VHF units. Some can even do full-duplex. In the case of HF, this normally means a second receiver that tracks what the transmitter does.

In the case of VHF, there is a diplexer and second receiver. VHF units normally can only go a little bit out of band without retuning, and the diplexer will Not do the 2 meter split! VHF units are also 25 KHz step radios, with the newer ones able to do Other than a power selector switch they are just like any Astro Sabre radio, and even have encryption.

Note that although the radios are digital, it is British maritime digital, extra channels that are in use only in the UK, Australia, and parts of Canada, not something useful in the US without a firmware update. These are good for general Ham Radio use any mode, including FSKas well as experimenting in the meter band now that meter CW has been discontinued by the commercial and government services.

W2NSSep 13, There is really no need to do any mods, they already cover the Amateur bands. The only really bad thing about marine radios is the lack of filter selections and no true VFO operation. Quite a few do KHz to 32 MHz with no gap by just removing the band limits.
