GM   아직도 햄들에게서 극찬받는 드레이크의 명기. <img src="https://t1.daumcdn.net/cfile/cafe/26370E3954A7276502" class="txc-image" style="FLOAT: none; CLEAR: none" actualwidth="640" data-filename="DSCN0769.jpg" exif="{}" border="0" hspace="1" vspace="1" width="640" id="A_26370E3954A7276502E5D5"/>   <img src="https://t1.daumcdn.net/cfile/cafe/2220933354A7277E22" class="txc-image" style="FLOAT: none; CLEAR: none" actualwidth="640" data-filename="DSCN0771.jpg" exif="{}" border="0" hspace="1" vspace="1" width="640" id="A_2220933354A7277E22CC19"/>   <img src="https://t1.daumcdn.net/cfile/cafe/2456F83754A7AE060A" class="txc-image" style="FLOAT: none; CLEAR: none" actualwidth="640" data-filename="DSCN0792.jpg" exif="{}" border="0" hspace="1" vspace="1" width="640" id="A_2456F83754A7AE060A4E2D"/>   <img src="https://t1.daumcdn.net/cfile/cafe/230B453B54A7AE250B" class="txc-image" style="FLOAT: none; CLEAR: none" actualwidth="640" data-filename="DSCN0795.jpg" exif="{}" border="0" hspace="1" vspace="1" width="640" id="A_230B453B54A7AE250B502A"/>   <img src="https://t1.daumcdn.net/cfile/cafe/2256043A54A7AE4203" class="txc-image" style="FLOAT: none; CLEAR: none" actualwidth="640" data-filename="DSCN0797.jpg" exif="{}" border="0" hspace="1" vspace="1" width="640" id="A_2256043A54A7AE420308A4"/>   <img src="https://t1.daumcdn.net/cfile/cafe/2220F73854A7AE7D19" class="txc-image" style="FLOAT: none; CLEAR: none" actualwidth="640" data-filename="DSCN0881.jpg" exif="{}" border="0" hspace="1" vspace="1" width="640" id="A_2220F73854A7AE7D193C97"/>     <TABLE border=0 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD vAlign=top align=middle> Drake 2-B Receiver Performance Test </TD></TR> <TR> <TD height=30></TD></TR> <TR> <TD vAlign=top align=middle><IMG alt="Drake 2-B" src="https://img1.daumcdn.net/relay/cafe/original/?fname=http%3A%2F%2Fwww.w1vd.com%2FDrake2-B.jpg"> </TD></TR> <TR> <TD height=10></TD></TR> <TR> <TD vAlign=top width=600 align=left> Drake 2-B </TD></TR></TBODY></TABLE>         <TABLE border=0 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD vAlign=top align=left>Band <TD>MDS <TD>Blocking <TD>Two-tone D.R. <TD></TD></TR> <TR> <TD vAlign=top align=left> <TD> <TD>(20 kHz) <TD>(20 kHz) <TD></TD> <TR> <TD vAlign=top align=left> <TD> <TD> <TD>  <TD></TD> <TR> <TD vAlign=top align=left>80 meters <TD>-139 dBm <TD>117 dB <TD>83 dB <TD></TD> <TR> <TD vAlign=top align=left>40 meters <TD>-140 dBm <TD>118 dB <TD>84 dB <TD></TD> <TR> <TD vAlign=top align=left>20 meters <TD>-138 dBm <TD>118 dB <TD>87 dB <TD></TD></TR></TBODY></TABLE> <CENTER> <TABLE border=0 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD width=600></TD></TR> <TR> <TD height=50></TD></TR> <TR> <TD vAlign=top width=600 align=left> AM Audio S/N: 33 dB AM Audio Frequency Response: </TD></TR></TBODY></TABLE> <TABLE border=0 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=60></TD></TR> <TR> <TD vAlign=top colSpan=11 align=left> <TD>  <TD></TD> <TR> <TD vAlign=top align=left>100 Hz <TD>200 Hz <TD>400 Hz <TD>600 Hz <TD>800 Hz <TD>1 kHz <TD>2 kHz <TD>3 kHz <TD>4 kHz <TD>5 kHz <TD>6 kHz </TD></TR> <TR> <TD vAlign=top colSpan=11 align=left> <TD>  <TD></TD> <TR> <TD vAlign=top align=left>-16 dB <TD>-3 dB <TD>0 dB <TD>0 dB <TD>0 dB <TD>0 dB <TD>-5 dB <TD>-30 dB <TD>-36 dB <TD>-42 dB <TD>- </TD></TR></TBODY></TABLE> <CENTER> <TABLE border=0 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD height=60></TD></TR> <TR> <TD vAlign=top width=600 align=left> AM Audio Distortion: </TD></TR></TBODY></TABLE> <TABLE border=0 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=54></TD> <TD width=222></TD></TR> <TR> <TD vAlign=top colSpan=11 align=left> <TD>  <TD></TD> <TR> <TD vAlign=top align=left>Mod% <TD>100 Hz <TD>200 Hz <TD>400 Hz <TD>600 Hz <TD>800 Hz <TD>1 kHz <TD>2 kHz </TD></TR> <TR> <TD vAlign=top colSpan=11 align=left> <TD>  <TD></TD> <TR> <TD vAlign=top align=left>30% <TD>63% <TD>16% <TD>5.6% <TD>4.0% <TD>3.5% <TD>3.2% <TD>4.5% </TD> <TR> <TD vAlign=top align=left>50% <TD>71% <TD>13% <TD>5.0% <TD>8.9% <TD>11% <TD>10% <TD>5.0% </TD> <TR> <TD vAlign=top align=left>70% <TD>56% <TD>14% <TD>13% <TD>16% <TD>18% <TD>14% <TD>5.0% </TD> <TR> <TD vAlign=top align=left>90% <TD>63% <TD>22% <TD>18% <TD>20% <TD>20% <TD>18% <TD>5.0% </TD> <TR> <TD vAlign=top align=left>100% <TD>63% <TD>25% <TD>20% <TD>22% <TD>22% <TD>18% <TD>5.0% </TD> <TR> <TD height=30></TD></TR></TR></TBODY></TABLE> <CENTER> <TABLE border=0 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD width=600></TD></TR> <TR> <TD height=30></TD></TR> <TR> <TD vAlign=top width=600 align=left> Notes: AM frequency response was fairly restricted due to the 3.6 kHz maximum i-f bandwidth. AM distortion numbers show the somewhat typical increase at lower audio frequencies - most often caused by the low audio frequencies riding on the AGC line. Also there is the usual increase in audio distortion as the modulation percentage increases. This is due to the detector's inability to cleanly demodulate the higher amplitude levels. Did not have a chance to investigate why the distortion numbers were significantly worse than the Drake 2-A. </TD></TR></TBODY></TABLE></CENTER></CENTER></CENTER>

첫댓글 외양은 라디오 같기도 하고, 무전기 같기도 하고, 미제답지 않고 그져 이쁩니다.
오디오의 영국제 쿼드 같은 느낌이 항상 납니다.

외양이 그래서 책상위에 올려 놓으면 그런대로 이쁩니다. 그리고 수신음도 괜찮구요..

기왕에 보여줄려면 홀딱 벗은 모습을 보여주셔야지....hi

부산은 따뜻하지만 지금 서울 갈현동 무척 춥습니다. 참고로 충주는 영하 14도입니다.
홀딱 벗으면 동태가 되거나 감기 들어요.ㅋㅋ

@HL3IB Drake 2B는 예전부터 명기로 소문이 났지만 전 아직 내부구경을 못했걸랑요?

이것이 동사의 R-4나 하마런드의 최고봉인 SP-600 혹은 콜린스의 75A-4 보다 중요한 스펙에서 우위를 점한다 라는
점을 아시는지요? 저도 W8ZR 홈페이지를 보고 놀랐습니다. 그래서 인기가 있나???.
