Looking at how I would configure a 7360-type mixer in the front end of a low-band (say 80M and 40M) receiver. Method A: To me, the most obvious way to do it is to feed the RF into the 7360's grid, and feed the deflection plates with balanced local …

The RCA 7360 is a special beam deflection valve for the generation of SSB signals. A carrier suppression of up to 60 dB was possible, a very respectable figure. It is probable that this type of valve was developed from the UHF beam deflection mixer Type 1636 of 1944. The maximum ratings are not close to the typical operating conditions.

The 7360 beam-deflection tube as used in this circuit combines two basic functions - it generates its own 456.85 kc carrier as a crystal-controlled oscillator, and it also functions as a balanced modulator which delivers both sidebands without the carrier to the mechanical filter.

In this article circuits will be described which make use of the 7360 as a balanced modulator, a frequency mixer and a product detector. Balanced modulator circuits will be shown for both the filter and phasing methods of SSB generation.

2021年7月28日 · The architecture of this radio was unique, in that the RCA-7360 beam-deflection mixer was dual-function; receiver front-end, and transmitter balanced modulator. On receive, the preselector output was applied to the grid, and the local oscillator to the deflection plates.

6 天之前 · Various modifications were then made to improve performance: the mixer was changed to a 7360, the VFO to 2SK19*2, the product detector to an SN16913 and the AF amplifier to an LM380.

2012年2月17日 · 7360は非常に優れたバラモジ管であるとされている。 嘗てハムジャーナル誌に連載されたJA1AEA鈴木OMによる「おはなしシングルサイドバンド」記事中にも、7360を使ったバラモジの「なめらかな変調音は特筆に価する」と記されていた。

Tube 7360 or Röhre 7360 ID4067, Electron beam switch tube, Noval, 9 pin miniature (USA pico-9) B9A and shown. Radio tubes are valves.

2021年10月2日 · In the cycle 20 ages, home-brew receivers with the RCA 7360 (sheet-beam tube) mixer were manufactured and used by enthusiastic amateurs of 50MHz. 7360 is not only low-noise and high-gain but also is strong against overload.

Has anyone tried a 6JH8 in place of a 7360 for the first mixer in a homebrew RX? How did they compare? Pete
