Timco Engineering Inc. 849 NW SR 45 Newberry FL 32669 page 1 Mario de Aranzeta Engineer Timco Engineering Inc. To: Andy Leimer Re: FCC ID PT9SDU-2000 Ref # 21335 731 Confirm #: EA102679 1) The BW plots do not appears to be for the maximum data rates. It is not clear as to what the 825 Hz tone represents. Submit new BW plots at the maximum data rates. The plot is marked in error. I’ve looked at the original plot in o ur records. It is marked (o n the reverse side) 9600 baud with an 825 Hz deviatio n (the peak deviatio n). This plot is identical to the plot on the next page but at a different center frequency. I’ve included a revised plot (labeled correctly) as page 5 of this note. 2) The calculations for Authorized BW (2M + 2D) were done with a peak deviation of 0.4 kHz for 25 kHz channel spacing and 0.825 kHz for 12.5 kHz channel spacing. Please explain why this was done. If the deviation is increased any higher it will exceed the allowed bandwidth as per the equatio n. The deviation is set at the factory based on the license of the final customer. I noticed a typographical error o n page 1 of the report in the calculatio n for the 25 kHz BW the 10.4 is incorrect and 0.4 is correct as in the information above the equatio n. A corrected page is enclosed as page 2 of this note. 3) Provide measurement details for radiated spurious emissions. Provide a sample calculation. The radiated spurio us emissio n page sho uld have a statement that the procedure used was the substitution method in TIA/EIA 603-.2.2.12. This line was inadvertently omitted from the page. These are dBc values (below the carrier). A corrected copy is enclosed as page 3. 4) The Tune-up Procedure says to set the power to 2 +- 0.05 Watts. The application is for 4.5 Watts conducted power. Explain this discrepancy. The SD2000 device is the same exact radio as a previo us product except for the change in o utput power from 2 watts to 4.5 watts which was do ne by changing the final RF semiconductor device.. The tune-up procedure submitted by the customer was for this previo us product and failed to reflect the change. A new page reflecting this change is included as page 4.

To: Andy Leimer email: [email protected] Re: FCC ID PT9SDU-2000 Ref # 21490 731 Confirm #: EA102679 1) Explain why their is an identical application Granted under FCC ID: PT9SDU-7000 (TC694638). 1) Originally the applicant was offered to submit this job to a TCB. But the questio n of use in a fixed and/ or mobile applicatio n came up (a TCB only being able to approve a fixed mounted product in this power range). The users manual originally reflects a fixed mo unting for submission to a TCB. The applicant then asked us to not submit it for TCB approval for this reason. Unfortunately, the users manual was not updated to reflect this. Later, the applicant having a customer who wanted a fixed mounted product and seeing a shorter time to market for this customer, changed the FCC ID and asked for approval of a fixed mounted device. The applicant applied for a TCB grant with this stipulatio n on the grant and in the users manual (same as sent to FCC). Attached is page 3 of the users manual that sho uld have been sent with the FCC submission. The applicant wo uld still like an FCC approval for the SD2000 product so their customers may obtain fixed and mobile licenses using this product.

It is marked exhibit 3 and was page two of my last note (I’ve included it again as page 4). I have excerpted both RF exposure statements and included the exposure statements from BOTH users manuals here (page 3). As to antenna specifications, I am under the understanding that at the time TecNet Global’s customer obtains their license to use this radio, compliance with RF exposure will be addressed and that the manufacturer of the radio does not have to address the antenna issue. TecNet Global supplies only the radio and not an entire system to the customer. I am submitting a MPE calculation based on a worst case installation of this radio.
