The yaesu ftdx3000 transceiver should provide weak signal receiver performance in crowded strong signal environments because of the receiver s down conversion roofing filters.
Ftdx3000 roofing filters.
The first if frequency is 9 mhz.
20 khz ip3.
Crystal roofing filters produce phenomenal multi signal characteristics the down conversion type receiver construction is similar to the ftdx5000.
This new transceiver has crystal roofing filter technology that has been proven in the ftdx 5000.
3 khz crystal roofing filters characteristics of the crystal roofing filter 300 hz center.
The 3 khz roofing filter is very effective in attenuating interfering signals.
For 1 380 and both have a 100 rebate.
With the 300 hz roofing filter it is so much.
The ftdx3000 is selling for 2 300 at hro and the ftdx1200.
The various ftdx3000 functions are displayed on this lcd and provide the operator with easy to read operating information.
The yaesu does have more roofing filters and an lcd screen.
Anyway from what i understand your ftdx3000 has similar if based dsp filtering so i d expect you wouldn t get much use out of the 300 hz crystal filter unless you frequently experience that problem with very strong adjacent frequency signals that you want help suppressing.
Down conversion receiver and powerful narrow bandwidth crystal roofing filters the powerful narrow bandwidth crystal roofing filter enhances the receiver multi signal characteristics.
As previously stated the 300 hz filter can be used on both data and usb.
R flt roofing filters nterference ejection r flt r oofing ilters narrow band roofing filters of 15 khz 6 khz 3 khz 600 hz and 300 hz requires optional xf 127cn cw narrow filter bandwidths are provided in the first if right after the first mixer.
At 600 hz i can just start to understand the person talking.
The usb signal will not be intelligible though.
I have both the 300 hz and 600 hz yaesu receive filters installed.
Note that ft dx 3000 rx filtering is continuously variable and implemented in a dsp sdr if back end.
300 hz cw narrow crystal filter for the ftdx 3000.
106 db sig 126 dbm 20 dbm 14 mhz band cw bw 500 hz ipo on roofing filter 600 hz.
The down conversion 9 mhz 1st if frequency receiver construction can realize narrow 300 hz optional 600 hz and 3 khz bandwidth roofing filters.
Implementing the extra sharp crystal roofing filters provides superior close in dynamic range and affords the best receiver performance possible.
The 300 hz roofing filter has a dedicated slot in the ftdx 3000 chassis and does not preclude any other filters.
The first if frequency is 9 mhz and a low noise figure dual gate mos fet d quad dbm double balanced mixer with excellent intermodulation characteristics is implemented in the mixer section.
